1.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
2. national standard GB11032 and ANSI 62.22, 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.
3.Products with detachment device can provide signals for quitting operation when failure occurs,
avoiding arrester explosion, and it is maintenance-free.
4.Polymer housed products with a six CTI level,creepage distance meets the requirements of IV level in
heavy pollution areas.
