Product Details

Combination type metal-oxide surge arresters for the three-phase

Product Description

PRODUCT DESCRIPTION

The introduction of function:
3 phases over voltage protecter(also called Combination type metal-oxide surge arresters without gaps for the three-phase) is an over-voltage protective device developed by our company. It is mainly used for the power supply system of power supply enterprises and electric power users, especially suitable for protecting the high-voltage motor, switch cabinet, power transformer, electric reactor etc.

Features of product:

1.This product is featured with unique structure, good looking, superior performance .It improves the safety level of the equipment protected.

2. It can protect the high-voltage motor well.
