Metal oxide arrester provides best protection against over-voltage to HV equipment,for instance,transformers,cables and switcher
These arresters belong to the Series 1,namely Polymer Housed Metal-Oxide Surge Arrester.Micro ampere level current flows while MOA is operating under normal voltage,but the amount of the current will be thousands amperes when MOA is subjected under over-voltage,because of MOA has a good non-linear characteristic.
Series 1 Polymer Housed Metal-Oxide Surge Arrester without gap,Voltage class 6-36kV, all ratings are available from 5kA to 10kA.
Series 2 Polymer Housed with Different diameter sheds Metal-Oxide Surge Arresterwithout gap,Voltage class 6.3kV-36kV,all ratings are available from 5kA to 10kA.
Series 3 0. 28~36KV porcelain housed zinc oxide surge arrester without gap,allratings are available from 5kA to 10kA.
Series 4 Station Class Surge Arrester, 54~258kV,all ratings are available from 5kA to 10kA, polymer housing and porcelain housing.
