220KV Station Class Polymeric Housed Zinc Oxide Lighting Arrestors Made by Metal Oxide Resistor
Description of 69kv arresters:
Surge Arrester is a device to protect electrical equipment from over-voltage transients caused by external (lightning) or internal (switching) events.
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.
Our advantages:
Due to their very high mechanical stability, polymer arresters from YongDe are best suitable for applications up to 550 kV networks as well as for areas with high seismic activity. Even after an arrester failure our polymer arresters will maintain more than 75% of their mechanical stability.
