Specially designed for 130 Volt networksLightning and overvoltage protectionunits for BrazilOBO can now offer a wholerange of lightning protectorsand overvoltage conductorsfor the Brazilian market.All products are TOV-tested to thefuture IEC standard 61643-2 andspecially designed for 130 V networks.The lightning conductor units are: V25-B/0-130 V25-B/2+NPE-130 V25-B/3+NPE-130 V25-B/3+NPE-130-FSAll units share the advantage thatthe protection function is retainedeven in the event of a networkfailure.Lightning conductor CLA 25-Boffers the benefit of an encapsulated,non-arcing spark gap. Furtherfeatures of this unit are the highdischarge capacity of 25 kA(10/350 µs) and the low responsevoltage of 1.5 kV. The conductorcan be plugged into the V20-Cbase part.Four class C surge arresters toE-DIN VDE 0675 Part 6/A1 arealso designed for the Brazilian130 V network. These units too;retain their protective functioneven in the event of a networkfailure. The types are as follows: V20-C/0-130 V20-C/2+NPE-130 V20-C/3+NPE-130 V20-C/3+NPE-130-FSThe surge voltage fine protectorKNS-D was developed for use insocket and switch combinations.This unit, specially designed forthe 130 V nominal voltage, fitsunder every commercial blank orunit cover with standard 22.5 mmopening and can therefore be integratedsmoothly into an existingelectrical installation.The protective circuits of theprotection unit are thermallymonitored at all times. Any faultis signalled both visually andaudibly.Overvoltageprotection approvedfor the US marketNew markets are openingup for the OBO V20-C surgearrester. The unit has receivedUL approval, which isessential for sales on the Americanand New Zealand markets.The UL certificate confirms thatthe OBO product can safely beused as a surge arrester. This certificateis issued on the basis ofsafety tests including fire testing.16Screws? No thanks!OBO completesthe plug terminal rangeWith some new productintroductions, OBO hascompleted its tried andtested range of plug terminals.Further informationwill be found in theVBS catalogueNewcomers to the range are plugterminals for two, three, five oreight single-cored conductors witha cross-section of 1-2.5 mm 2 or0.75-1.5 mm 2 .The plug terminals are made ofpolyamide and are designed fornominal voltages up to 450 V.
Tested components are vital in lightning protection systemsEvery protection system isonly as good as its weakestlink. This principle applies inparticular to lightning protectionsystems. Tests by the LightningProtection & EMC TechnologyCentre (BET) in Menden haveshown that all householders mustbe urgently advised to ensure thatall components in such systemshave the proper test and qualitycertificates.A lightning protection systemusually consists of the followingfunctional units: receiver rod: part of the outerlightning protection used toattract the lightning conductor: part of the outerlightning protection intended toconduct the lightning from therod to the earthing unit earth rod: part of the outerlightning protection systemwhich discharges the lightningto earth for distribution lightning protection equipotentialbar: part of the inner lightningprotection system used to reducethe potential differencescaused by lightning currentThe various functional units of thelightning protection system arelinked together by special connectingelements. These components,which take various forms,play an important role in the functionof the entire system.And they must survive difficultconditions: changing weather conditionssuch as rain, storm, frostand heat, and in the case of adownpipe, the extreme loads fromthe high lightning current.The Lightning Protection & EMCTechnology Centre (BET) has testedconnectors of various forms andmaterials thoroughly and foundconsiderable differences. Oneresult of the tests was that dependingon the material used, evennormal weather-induced corrosioncan threaten the functionalreliability of a lightning protectionsystem.Hence the clear recommendation:when buying lightning protectionsystems, ensure they have therequired test and quality certificates.The RAL Quality Association forLightning Protection Systems hasshown the way. This associationgroups together around 30 qualityawarespecialist companies, andwith its ”Quality and test conditionsfor the installation of lightningprotection systems” supportsthe objective of supplyingstate-of-the-art systems andawards these the RAL qualitymark from independent testers.All OBO lightning protection unitsalso carry the test mark of theLightning Protection and EMCTechnology Centre (BET).17
