Product Description

High Voltage Equipments 220kV Polymer Lightning Arrester

specification

1. Lightning 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.
• E creepage distance of porcelain housed products is wide which is suitable for IV level heavy pollution areas.
