1.Models:6kV~500kV 2.Silicone rubber housing 3.Good protective properties 4.ISO9001-2008 certification

Production:

Cable surge voltage limiter is mounted between cable metal security layer and ground, under normal circumstances, the current through the cable protective is very small, in microamps level ,when overvoltage appears, protective layer protector quickly put into operation, discharge the cable protecting layer and ensure the safe operation of the cable.

 

Product feature:

ZnO varistor as a protective element,without the series gaphas excellent nonlinear volt-ampere characteristic curve.good electrical insulation properties.High dielectric strength,Electrical erosion resistanceexplosion-proof and with good chemical stability.hydrophobic, sealing performance.
