General planning aidProcessing materials with the correct toolDifferent materials must be processeddifferently. Chop saws haveproved to be very useful when layingdevice installation trunking.This allows exact cutting.Trunking made of PVC andPC/ABS:• Hand saw, fine-tooth (iron saw)• Piercing saw with iron or plasticsaw blade with fine teeth• Circular saw with plastic sawblade, 350 mm diameter,80–108 teeth/inch and 2,800rpmSheet steel and aluminium trunking:• Ribbon saw with saw ribbonfor hard metals• Circular saw with saw bladefor hard metals, 350 mm diameter,80–108 teeth/inch and2,800 rpm• Angle grinder with metal separatingdiscTake the length expansion ofthe materials into accountDifferent materials expand differentlyand this must be taken intoaccount. The expansion of the materialsPVC, steel and aluminiumcan be calculated using the formulabelow.ΔL = L · α · ΔTL = Length mα = Thermal expansion co-efficientΔT = Temperature change• Steel: 14 x 10 -6 /1 K• Aluminium: 23.1 x 10 -6 /1 K• Hard PVC: 71 x 10 -6 /1 KExamplesAt a temperature difference ∆T of20°, the 2,000 mm standardlength changes as follows:• For hard PVC, 2.84 mm• For steel, 0.56 mm• For aluminium, 0.924 mmPerfect interplay for more efficientworkingFaster and better installation sequences– this is the aim of bothourselves and the manufacturersof electrical devices. Previouslyused bolt-firing devices have thusbecome modern nail guns. With itsPulsa 700E, Spit can offer devicesof the highest quality for this areaof the electrical industry. ManyOBO products can be processedparticularly efficiently using the devices.This is proved by testsfor mounting cable and device installationtrunking, carried out withSpit devices.Thermal expansion coefficient:Properties of the hard PVC usedProperty Value DINMaterial designation PVC-U-E-D-08-04-28 to DIN 7748Tensile strength min. 40 N/mm² to DIN 53 455Crack expansion min. 85% to DIN 53 455Breakdown voltage min. 20 KV/mm to DIN 53 481Surface resistance min. 1,010 Ohm to DIN 53 455Shape heat resistance min. 75 °C to DIN 53 400/BTemperature resistance in the application max. 65 °CFlammability Level V0 to UL 94Glow wire test 960 °C to DIN IEC 695You can find more details in the chapter "Chemical resistance of hard PVC" in the "Additional information" part.06 LFS_Katalog_2010_Neuer_Stand / en / 25/02/2010 (LLExport_00995)10 OBO LFS
ColoursGeneral planning aid06 LFS_Katalog_2010_Neuer_Stand / en / 25/02/2010 (LLExport_00995)RAL, NCS, DBThe wide range of standard coloursand the many possible specialcolours mean that it is possibleto integrate the colour of thecable routing systems into any officelandscape. The plastic cabletrunking and device installationtrunking systems are available inthe RAL colours pure white (RAL9010), light grey (RAL 7035), grey(RAL 7030) and cream (RAL9001) as standard. The device installationtrunking systems andservice poles are made of sheetsteel or aluminium and are availablein the standard colours purewhite, light grey and cream. Powdercoating means that all the otherRAL colours are possible onsheet-steel and aluminium trunking.Alternatively to the RAL standard,both NCS and DB colours canbe applied on request.LFSOBO11
