Latest Electrical Equipment Porcelain Ceramic Zinc Oxide Surge Arrester without Gap 66KV
Porcelain Lightning Arrester Description:
Porcelain Surge Arrester for 35~220kv alternating system
Main features: It adopts double sealing structure, the core
encapsulates by molded silicone rubber which completely solves the
sealing problem of porcelain housed products.
It has a two-way pressure release structure.
Its core component ZnO varistor has good pressure ratio,
consistency, large flow capacity and high reliability.
0.28kV~500kV Surge Arresters' Characteristics:
1. 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.
2. Polymer Housed with silicone rubber, explosion-proof ZnO
varistor as the core component is large
in flow capacity.
3. International standard IEC 60099-4 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.
4. Products with detachment device can provide signals for quitting
operation when failure occurs,
avoiding arrester explosion, and it is maintenance-free.
5. Polymer housed products with a six CTI level, creepage distance
meets the requirements of IV level in heavy pollution areas.
