51kv Ploymer Housed Moa Surge Arrester With DisconnectProduct's Characteristics:The Core column applied winding structure, Polymer Housed core pillar molded on the core column, with almost no internal air gap, and outstanding sealing performance
Simple in structure, small in size and light in weight
Polymer Housed with flexible silicone rubber, explosion-proof
ZnO varistor as the core component is large in flow capacity which is much higher than that of the national standard GB11032, and with high reliability.
With fully insulated tops, the product can be applied to the complete cabinet installation, which can reduce the designing size of cabinet.
Products with detachment device can provide signals for quitting operation when failure occurs, avoiding arrester explosion, and it is maintenance-free.
Polymer housed products with a six CTI level, creepage distance meets the requirements of IV level in heavy pollution areas.
