V B STotally metric, totally practical:The OBO V-TEC VM cable glandsThe quickest and most convenientway of providing strain relief andtightness with cable glands onjunction boxes is with the newV-TEC VM cable glands from OBO.With the integrated sealing lip andthe special OBO lamella technology,protection class IP 68 isachieved. Strain relief andtightness have been tested toDIN EN 50262.The connecting threads of thecable glands are metric and aretherefore suitable for universal use.Once screwed in place the fitting isthere for ever, as the optimumthread adjustment with the rightpitch ensures permanent resistanceto shaking.The cable glands are available inlight grey, silver grey and black –ideal for labelling and distinguishingof different functions.OBO also offer more top-classfeatures in the material: the cableglands are made of high-quality,halogen-free polyamide 6.Well protected: modern cap nutconstructionThe self-locking thread makesthe screw connection shakeproof.Snapping on, not snapping off:The OBO locking clipSomething new for individual cablefixing, too: the OBO locking clip isan example of this, and means thatan entirely new method of fixingand laying is now possible.The locking clip is particularly suitablefor hard, problem surfacessuch as concrete, tiles/full brickand sand-lime brick.All operations can now be carriedout very simply:1. Drill all holes2. Insert all locking clips3. Insert cable and lock at thesame timeOBO’s patented system is as simpleas it could be – errors are virtuallyexcluded. And the locking clipcan be opened again at any timewith a screwdriver.The locking clip makes electricalinstallation just that bitsimpler and quicker – typical ofOBO.Usability StudySimultaneously: insertion andlocking in.The locking clip makes anew, faster installationsequence possible: drill allthe holes, insert all the lockingclips, then lay in the cableand lock it in quicksuccession.6 | OBOBlick 1/2002

V B SNew design and new sizes:The Junior-Quick clipsReady for use: the new Junior-Quick clips type 2950 in sizes M40,M50 and M63. They are presentedin an improved design, with thesame load capacity as the Quickclips of type 2955. Another advantageis that they can be used inconjunction with all the otherJunior-Quick clips, Multi-Quickclips and in future also with thestarQuick clips.A real innovation of the new Junior-Quick clips are the round edges onthe clip opening. These not onlymake for an attractive design, butalso guide the clip into the rightposition when the pipe is pushedin.Particularly pleasing: the price ofthe clip will remain stable, in linewith that of the existing Junior-Quick clips.One for all:The OBO multi-purpose anchorAnchors have been around fordecades, and to be honest theyhaven’t changed very much in allthose years – until now. The newOBO multi-purpose anchor is trulya real innovation – it is manyanchors in one.The difference from traditionalanchors is evident even at firstsight: the body of the anchor has avariety of sizes of shank sections.The top one corresponds to themaximum anchor diameter, thebottom one to the minimum diameter.There is only one anchor for thestandard fixings for drill hole diameters6 mm, 7 mm and 8 mm. If a6 mm hole has been drilled thelowest anchor shank fits into it perfectly.When the anchor is pushedfurther into the drill hole, the upperanchor shank contracts and fitsitself to the smaller hole diameter –in that case, for example, a 4 mmscrew can be used. In an 8 mmhole the entire anchor fits in exactly.In that case a 6 mm screw is used,which expands the lower anchorshank.This means that one anchor can beused for different hole diameters.This is not only an advantage inpractice, say if a hole has openedup and a thicker screw is suddenlyneeded for fixing. It also rationalisessupplies: you need fewer differentpacks.The new OBO multi-purposeanchor is available in two differentsizes. They are made from highqualityhalogen-free polyamide andare an example of how even smallthings can improve efficiency.Usability StudyTypical: The anchor body with differentsizes of shank sections – fitsall standard drill hole diametersOBOBlick 1/2002 | 7

V B SOBO’s top stars:starQuickOBO 3OBO 4OBO 5OBO2A33A44A55AstarQuick is a comprehensiverange of high-quality clips, whichare particularly suitable for use outdoors,in public areas and in multistoreycar parks or under bridgesand on exposed steel structures.They are unaffected by environmentalinfluences. The clips aremade of a UV and weatherresistantpolyamide.The series, with a total of 13 differentsizes and a clamping rangeof 10 – 65 mm, makes possibleproblem-free support of all kinds ofpipe systems. starQuick can holdboth plastic and metal pipes, so issuitable for electrical and for sanitarysystems. The clips can be fittedon the wall or on the ceiling.Fitting is amazingly quick anduncomplicated – even withouttools.8 | OBOBlick 1/2002

V B S6OBO 7OBO 8OBO 9OBO66A77A88A9Installation of several pipes is verysimple: by stringing together individualclips, by using the double holder, toguarantee secure holding andspacing under a high load, by attaching rails for a free choiceof distances and number ofclips.starQuick is reliable and can withstandhigh loads. A patented safetysystem ensures that the pipesremain permanently in their place.The pipe is held securely by theencircling closed clip.Another big hit:The OBO pressure clipThe quicker, the better – this alsoapplies to the installation of intermediateceilings and partition walls.That is why we have not onlychanged the design of our pressureclip, but also its function. As before,assembly is very simple usingthe M6 hammerfix. A new feature isthe striking surface on the top,which guarantees high strikingaccuracy in the hammer-drivescrew. After assembly the cablesare passed under the clips in a“lasso technique” hand movement– and that’s all there is to it.Of course the pressure clip is madefrom high-grade polyamide – afterall, you can always expect only thebest from OBO.OBOBlick 1/2002 | 9

V B SIngenious locking system:The OBO Quick-PipesystemQuick-Pipe combines the advantagesof cable duct and installationpipe in an intelligent system. Itallows clean and reliable surfaceinstallation of all kinds of cables onthe wall and ceiling, including 230V cables, data cables, fibre-opticcables, coax cables and telephonecables.Quick-Pipe offers a whole range ofconvincing advantages over theinstallation pipe and cable duct.Insertion of the cable is definitelyeasier: laborious threading in is eliminated.Retrofitting is always possiblewithout problems – in fact it iseven simpler than the first installation.Data cables can be fed in veryeasily, as can pre-assembledcables with plugs fitted. Unlike thecable duct, the Quick-Pipe has onlya few support points, so it is ideallysuited for uneven surfaces. It consistsof only one part, which ismade up from two materials: a rigid10 | OBOBlick 1/2002

V B SMulti-Quick ME:The OBO clip forall purposesPVC for floor and cover and aflexible component for the hinge(2-component technology). Sothe cover is integrated and cannotbe lost.It is as easy as can be to use: fitthe Junior-Quick clip, cut Quick-Pipe to length, clip in then insertthe cable, turn backwards –ready. With the intelligent constructionthe Quick-Pipe closesautomatically. Suitable fittingsallow flexible alignment. Thetwo-part fittings are simply clippedtogether and can be reopenedeasily again with ascrewdriver.This is a clip for all purposes: theOBO Multi-Quick ME covers thewhole range of pipe diametersfrom 16 to 32 mm with only threesizes. Until now this range requiredseven different clip sizes. And thebest bit: it doesn’t matter whetheryou are still using the existing Pgpipes or whether metric dimensionsare already in use – the OBOMulti-Quick is always right!But in view of the conversion fromPg to metric sizes, the name of theproduct has been changed. Theformer Multi-Quick is now calledMulti-Quick ME.It retains the product advantages ofthe OBO Multi-Quick, such as lightningfast release and automaticlocking, practical slotted holes forA comparsion of allOBO Multi-Quick MEsizes.OBO Multi-Quick typeOBO Multi-Quick ME 16/20OBO Multi-Quick ME 20/25OBO Multi-Quick ME 25/32problem-free alignment of the clipwhen mounted on the wall orceiling and also ease of insertionand adjustment of the pipes thanksto the optimally shaped holdingarms.

V B SStrike power:Holds in any kind of masonryThe OBO NailfixTo help you to fix cables in wallchannels and to masonry moreconveniently and securely prior toplastering, we have remodelled andoptimised the OBO Nailfix.The OBO Nailfix is suitable foralmost all backgrounds except forconcrete, including hard sand-limebrick and tiles. To ensure betteradhesion of plaster, the plasticcover has “plaster holes”. An optimumratio between bending angleand hardness ensures that the nailsdo not break.The Nailfix is variable and adapts tothe cable. Laying in narrow passagesis no problem with OBO-Nailfix,as it can be turned through 90°.Fixing pins make it easy to guidethe cable under the cover, evenafter the OBO Nailfix has beenhammered in.The OBO Nailfix: another qualityproduct from OBO to simplify electricalinstallation – and naturallyhalogen-free.Full adhesion:The holes in the fixing coverensure optimum adhesion ofplaster.Junction box OBO B9/T:Unlimited applicationsA universal problem-solver, whichcan be used virtually anywhere.Even in permanently wet positions.B9/T is the unspectacular name ofthis all-purpose junction box fromOBO, which can claim protectionclass IP 67.The B9/T junction box consists oftwo plastic components, a soft onefor the seal and a hard one for thehousing. The result of this dual plastictechnology is perfect tightnessand stability.But there are even more advantagesto this junction box. They include,for example, the soft membrane,which can be perforated directlyby the cable without any othertool and seals automatically, as wellas the anti-rotation cams, whichensure precise positioning and facilitateaccurate and secure fitting toall backgrounds.The fixing holes in the junction boxare provided with a soft component,which holds the fixing screwsto achieve the protection class.Maximum stability and distortionresistance is guaranteed by thelower section in fibreglass-reinforcedpolypropylene with its doubleouter wall.Other features of the B9/T are theterminal strip which can be rotatedthrough 360° and the smooth outerwalls, which allow several boxes tobe lined up without spaces betweenthem – even with retrofitting.The OBO junction box has of coursebeen thoroughly tested, as canbe seen at a glance from the lid.Here you will find test marks suchas VDE, CEBEC and KEMA KEUR.

V B SPG becomes “metric”:OBO facilitates conversion with clear labelling andtype listThe Europe-wide standardisation ofdimensions and sizes has not passedthe electrical industry by. Themost important changes in thisarea include the conversion of thePg system, which is mainly used inGermany, to the internationallystandard metric system.It must be said that the conversionimplemented last year has led to aconsiderable simplification. Fromnow on, instead of working with tenPg sizes, the user only has eightmetric sizes to think about. And thelabelling also has advantages: theexternal diameter of rigid and flexiblepipes and also the accessoriesnow correspond to the systemsizes of the metric size standardDIN EN 60423 – the external diameteris evident even from the typename.OBO Bettermannhasimplementedthe changequickly andconsistently:all productsare alreadyavailable inmetric sizes. The clear labelling ofmetric products with the characteristicM-logo provides an instantoverview, while a glance at the clearOBO type table will providedetailed information.OBOBlick 1/2002 | 13

V B SAll in white:The OBO WhiteLine.Pure Joy: ECO Series and Quick-Pipe in pure whiteWhite is increasingly in demand forelectrical installations. Particularly inwhite environments such as cellarsor garages, the colour purity shouldnot be disturbed in any way. That iswhy there is now the WhiteLine fromOBO: The whole ECO range and theQuick-Pipe system will in future alsobe available in pure white. But ofcourse Quick-Pipe and ECO are notonly attractive on the outside: itgoes right through.The refined, streamlined housing ofthe ECO junction boxes concealsmany intelligent details, which enablethem to be installed faster,more conveniently and thereforemore cost efficiently – and at nohigher price than for other products.Quick-Pipe combines the avantagesof cable duct and installationpipe in an innovative, intelligentsystem.

T B SNew Combi Controllerand Surge Controller:Effectivesurge protection„Made by OBO“Small in size, big in performance:The new OBO Combi Controllertype V 25-B+C is a compact lightningand surge arrester of requirementclass B and C to DIN VDE0675 Part 6 (A1/A2). The devicewas developed specially for use indwellings (to VDS 2031). If the buildinghas an external lightning protectionsystem (to DIN VDE 0185Part 100), the Combi Controllerensures effective and safe lightningprotection potential equalisation.The V 25-B+C is also capable ofprotecting buildings connected toan overhead power line. The deviceis designed to dissipate the highlightning energies that may occuron an overhead line in the event ofa direct lightning strike.Because of its low protection level(< 900 V) and its varistor-baseddesign,the Combi Controlleris also well suited to filtering anddiverting transients (short-term voltagesurges) from power supplylines.A significant advantage of the deviceis its compact design. This isthe result of the fact that only a17.5 mm housing is needed foreach arrester element.The OBO SurgeControllerV 20-C is apowerful surgearrester ofrequirementclass C. Withits nominaldischarge currentIn of 20kA (8/20), itcan protectbuildings fromdamage dueto energy-richvoltage surgesinjected galvanically,inductivelyor capacitively.The Surge Controller is usuallyused in distribution boards, whereit can be quickly and easily mountedon top-hat rails (DIN EN50022). Correct installation is madeeasier by a pre-wired base and clearlymarked terminals.With TN-S, TT and IT mainssystems, the 3+1 connection variantshould be used: The new OBOCombi Controller C 25-B+C withnon-reversible connections, combinedwith arrester elements V 25-B+C and V 20-C, ensures a highdegree of security against voltagesurges.The C 25-B+C (NPE spark gaparrester) is equipped with a newtype of protection against incorrectconnection which reliably preventsconfusion of the arrester elementsand ensures technically correctinstallation of the protection devices.OBOBlick 1/2002 | 15

T B SSurge protectionwith greater coordination:OBO presents two specialLightningControllersWhen combined with surge arrestersconnected in series immediatelydownstream, the new lightningarresters type MCD 50-B and MCD125-B/NPE ensure a coordinatedresponse, without the need foradditional decoupling elements.The fundamental advantages of theinnovative multi-carbon technologyof OBO LightningControllers arefully preserved.The low protection level of ≤ 1.3kV makes it unnecessary to installdecoupling inductances or to provideadditional lengths of conductorbetween lightning arresters(requirement class B) and surgearresters (requirement class C).This results in a space saving oninstallation of up to 45 percent, aOBO LSA-PLUS technology:The “plus” for more surge protection in data,measurement & control and communications networksOBO’s LSA-PLUS surge protectionis generally used in multi-wirewiring systems such as those thatoccur, for example, in measurementand control technology and intelephone exchanges.For example, with only one surgeprotection magazine type LSA-B-MAG (basic protection), ten twowiresystems can be protected.Module LSA-BF is used to protecta single two-wire circuit.It is important to distinguish between: Basic and precision protectionLSA-BF 180 (180 V version) fortelephone exchanges in analogand ISDN telecommunicationinstallations.

T B Sgreat advantage where compactEMC concepts are concerned. Inaddition, the separate NPE sparkgap at the surge arrester (requirementclass C) with compact TTand TN-S systems can be omitted.Preferred fields of application forthe new OBO devices are compactsurge protection concepts in separatehousings and the installation ofarresters of requirement classes Band C in a distribution board. Typicalapplications: Compact mobileradio transmittersThe advantages at a glance: Low protection level < 1.3 kV No need for a decoupling inductance or a length of conductorbetween arresters of requirementclasses B and C. Up to 45 percent space savingwith compact EMC concepts. Proven multi-carbon technologyin the LightningControllers .Surges don’tstand a chance:New protectiondevices for mobilesystems anddirectionalradio linksA new coaxial surge protectionadapter for mobile systems anddirectional radio links has beenadded to OBO’s TBS range. Thenew adapter has a 7/16 male connector(DIN) and is designed for thefrequency ranges 800 to 900 MHz(type LP 7/16-850 MF-C) or 1700to 1900 MHz (type LP 7/16-1800MF-C).The new surge arresters act as narrow-bandfilters. Only a narrow rangeof frequencies is passed by thedevices; other frequencies areshort-circuited and diverted. Withsurge arresters of this design, adirect short circuit is establishedbetween the inner and outer conductors.This short circuit takes theform of a coaxial line of preciselydefined length, an electrical wavelengthof one-quarter of the wavelength(l/4) of the frequency to betransmitted.surement and control engineeringsectors.Basic and precision protectiondevices with OBO LSA-PLUS technologyare fitted with fail-safe technology,which bridges the arresterin the event of a thermal overload,thus protecting it.Simply by mounting the LSA-PRO-FIL connection or isolator strip onthe PROFIL mounting tray, the surgearresters can be mounted onalmost any wall. The LSA-Plus simplewiring tool is all you need toinstall the wires without cutters,solder, screws or stripping. No sensitive trigger electronicsinside the lightning arresters. With compact TT and TN-Ssystems there is no need for theadditional NPE sum spark gapwith surge arresters of requirementclass C.The technology of the devices inoutline:MCD 50-B:The specially doped insulatingrings, which determine the preciselydefined spacing of the nine sparkgaps, guarantee the low protectionlevel (Up) < 1.3 kV. As with the provenMC 50-B/VDE, the modulararrester makes it possible to removethe upper part without interruptingthe mains voltage, in order tomeasure the insulation resistance inaccordance with TAB2000.MCD 125-B/NPE:The type MCD 125-B/NPE versionis an NPE spark gap intended tobe installed between the neutralconductor (N) and the protectiveearth conductor (PE). The low protectionlevel (< 1.3 kV) is achievedby a specially coordinated protectioncircuit.OBOBlick 1/2002 | 17

K T Ssurface of aDouble Dipcoatingball impact test:individuallygalvanisedDouble Dip:Innovative coating process for cable supportsystems offers many advantagesSteel is a material which is moreindispensable than ever in moderncable supports. Its outstanding useand processing properties and theexceptional value for money makesteel an irreplaceable constructionmaterial in almost every area.Modern steel materials are constantlybeing further developed,with particular attention to corrosionprotection. Hot dip galvanisinghas proved an excellent methodsince 1860. Since 1959 strip galvanisedsheet has been producedcontinuously in Germany. Zinc-aluminiumalloys have been used sincethe early 80s, while in 1998OBO supplied the first componentsfor cable support systems fromGalfan.A further development of this coatingprocess was achieved twoyears ago by a subsidiary in theThyssen/Krupp Group. By contrastwith the previous coating systems,in this “Double Dip” process thestrip to be galvanised passesthrough two zinc baths in successionwith different contents. Thefirst bath contains pure zinc, thesecond a zinc-aluminium alloy.With this innovative process Zn-Alcoatings of 70µ per side or 1000g/m2 on both sides are achieved,with at the same time excellent plasticityand high adhesion of thecoating. The coating produced inthis way is made up from a eutecticzinc-aluminium structure and azinc-aluminium-iron alloy coat.Zinc coat (in µ)605040302010Industrial airSea airCountry air5 10 15 20 25 30 35 40 45 50Protection duration in years (average values)Tests on sample components ofcable support systems in the DortmundSurface Coating Centre andinternally in the BET Institute confirmthe outstanding corrosion protectionproperties as comparedwith conventional zinc coatings.After 552 hours in a salt spray mistthe Sendzimir and also the hot dipgalvanised samples showed clearsigns of corrosion, while no red rustformation could be detected evenafter over 1600 hours in the DoubleDip samples in spite of bare cutedges.

K T Sconfirmed these outstandingresults.The wear rates forDouble Dip wiresball impact test: have already beenDouble Dip extrapolated to 15years. They werelower by a ratio of1 : 5 than for thick galvanised(330 g/m2) surfaces.Zinc-aluminium alloys have been inuse for over 20 years. The DoubleDip process for sheet metal is stillso new that it has not yet beendescribed in standards. The standardEN 10244-2 (2:2001) containsrequirements for wire coatingsin ZnAl. All standards for hotdip galvanised steel strip are beingrevised at international level. A newcombined standard will be producedfrom the three existing ones. Itwill also contain higher zinc-aluminiumcoat thicknesses, as are alreadyoffered by the Double Dip process.The DIN ISO 12944 seriescontains in six parts topics on thecoating systems for steel structuresand can also be applied tocable support systems. It recordsdifferent types of surface, environmentalconditions, service life,structural features and laboratorytests.In respect of the features describedin this series of standards, DoubleDip can be classified in the highestcorrosion class. In the still valid productstandard DIN VDE 0639 acorrosion protection classification isdescribed, while a revised classificationwill follow in the newlypublished IEC / EN 61537 (9:2001).New in the OBO range:Wide span cable traywith 160 mm high sidesCompleting the upper end of theOBO KTS range, the new widespan cable tray stands out with itsextremely high load-bearing capacityand low deflection. The widespan cable tray can withstand aload of 125 kilograms per metre,with a support spacing of 7,000mm. It is equipped with a 160 mmhigh, continuously perforated siderail and a base plate with transversebeads.Wherever extreme corrosion protectionis needed, cable supportsystems with Double Dip coatingsare an economical and ecologicallyconvincing solution. The mainadvantages: Ease of installation – no materialdistortion. No risk of injury to the fitters andno more cable damage fromburrs and zinc projections. No after-treatment needed onsite. Greater corrosion protection –longer service life for the sameprice. Very good adhesion of the zinccoat – no flaking under impactstress.

With its expandedrange OBO offers a selection ofsystems for comprehensive fireprotection.Cable insulationFor fire-resistant sealing of wall andceiling routings. These systemsprevent transmission of the fire toother sections via the cable andline network.Fire protection ductsFor securing and isolation of cablesystems in escape and rescue routes.FunctionmaintenanceThe use of special lines and layingsystems guarantees that all powercircuits with a safety function continueto operate in the event of fire.The grouped support OBO Grip Mcould always be used for functionmaintenance in combination witha long trough. But now it alsoworks without one. Correspondingtests have certified that groupedsupport OBO Grip M, type 2031M/15 achieves function maintenanceclass E30 even without along trough. It can bear a cableweight of up to 1.1 kg/m, correspondingto up to 16 telecommunicationcables.was bis zu 16Fernmeldekabeln entspricht.Suspension without threaded rodawarded classification E30One of the biggest problems withfunction maintenance in cable lineshas always been securing the brakkettips with threaded rods. Duringthe next cable laying at the latest eitherall threaded rods must be removedagain or the additional cablemust be laboriously threaded in.Now for the first time OBO Bettermannhas had a suspension with abracket without threaded rod protectiontested by a materials testinginstitute. With outstanding results: ata spacing of 1.5 m and a cableoccupation of 20 kg/m the systemon an OBO cable ladder achievedfunction maintenance class E30.Function maintenance alsopossible with mesh trayOBO can now also supply a meshcable tray for function maintenance.In corresponding tests the OBOmesh tray achieved function maintenanceclass E90 with supportspacing of 1.5 m and cable occupationof up to 20 kg/m. With itslow own weight and simple assemblythis system represents an interestingalternative to the functionmaintenance systems used previously.OBOBlick 1/2002 | 25

L F SWDK duct with new productadvantages:continuouslyadjustable cover clipProduct care for OBO‘s WDK ducts: incombination with the new cover clip,the line routing ducts allow continuousadjustment of the clips over the wholelength of the duct. To facilitate cable fitting,the clips are locked in on one sideand project forwards. This gives a 30°opening, so that the cables can be laidin quickly and without problems.The cover clip is placed on the ductfloor as it is supplied.Above a duct width of 100 mm the clipcan also be used as a connector in thefitting of line routing ducts.New device socketfor Switzerland added to the rangeFor Switzerland OBO Bettermannhas added a new, versatile devicesocket to its range. The socket islockable and is intended for use inskirting ducts made from plastic(GEK), steel (GES) and aluminium(GEA). The main advantage of thedevice socket is the variable possibilityfor fitting into the different ductsystems. Direct lining up of thesockets is not possible.LKM duct:special contour forpotential equalisationOBO designers have succeeded indevising a particularly intelligentsolution in the development of thenew LKM duct. The newly developedlocking contour of the ductensures that potential equalisationand a protective conductor functionare created between the upperand lower sections – entirelywithout accessories.The newly developed cover clampalso simplifies the overhead fittingof the cables in the line routingducts.26 | OBOBlick 1/2002
