Product Introduction

HXGN-12 AC high voltage fixed metal enclosed ring network switchgear is a ring network switchgear that can be configured with vacuum load switches, circuit breakers, fuses, and disconnectors.

The fully air-insulated structure makes the product more stable and reliable; the visible isolation break and the complete "five-protection" mechanical interlocking settings make the product safer to use.

The cabinet has a compact and simple structure, flexible operation, easy installation, and multiple interlocks, which can improve power supply parameters and performance as well as power supply safety.

It is particularly suitable for power distribution in urban residential areas, small secondary distribution stations, small switch stations, industrial and mining enterprises, shopping malls, airports, subways, power stations, hospitals, stadiums, railways, tunnels and other places for receiving and distributing electric energy.
