Distribution Surge Arrester

Description:

Distribution type surge arrester is designed to serve in distribution system and provide over-voltage protection. The varistor used in the arrester is subjected to a series of physical and electrical tests to ensure the protective ability, and the high-level housing verifies the insulating properties. The arrester has been designed and type tested according to IEC60099-4:2004 standard.

Features:

Excellent protective performance.

KEMA tested quality assurance.

High level of reliability and durability.
