Multi-Chamber Arc Blowing Type 10kv Fixed Gap Line Protection Device

https://jecsany.en.made-in-china.com/SpecificationHighest voltage for equipment can be up to 13.2 kV.Protects from Induced OvervoltageNo maintenance is requiredNo special grounding requiredThe outer air gap has been fixed before installation, and the components have been pre-assembledProtection against: IOVOnly 1 product per pole is requiredProducts are installed with phase alternation (А -> B -> C)Definitely great use and the highest possible reliabilityLine Protection Device has been designed to ensure the most effective protection from indirect strokes. This device is able to perform as highly effective lightning protection system, providing secure power network operation in 80% of such issues.In order to protect sensitive equipment, such as pole-mounted transformers (PMT), conventional metal oxide surge arresters still must be usedOperational PrincipleEnsuring a high ability to discharge excessive energy of an overvoltage in the surrounding atmosphereThe induced overvoltage will create an electrical power arc between the terminal electrode of a MLPD and the conductor clamp on a line. First, the arc will be divided into a series of small arcs by a series of discharge chambers, and then quickly extinguished when the oscillating current of the grid exceeds zero.Make full use of the grounding resistance between two towers, each tower only needs to install one productIt is used for the protection of overhead line induced lightning overvoltage, which is more cost-effective than traditional solutions.ParametersDescriptionUnitValueElectrical line parameters  Highest voltage for equipment kV13.2Maximum prospective fault currentkA1,5External air gapmm50±1050% flashover voltagekV85Power frequency withstand voltage kV (wet/dry)20/30Lightning parameters  Lightning discharge capability  (200 μs) C1.0High current impulse (4/10 μs)kA65Nominal discharge currentkA20General Parameters  Additional power losses on the line%0Average expected lifespanyears20UV resistance h1000Weightkg2.5Maintenance 1 visual verification per yearAccording to IEC 60038, According to IEC 60071-1, According to  IEC 60099-8, According to ISO 4892-2, method A, IEC 62217   SizeInstallation/* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
