Product Overview
Medium Voltage Switchgear
The series fully gas-insulated metal-enclosed switchgear (hereinafter referred to as “GIS”) is a new generation of modular, highly reliable, compact and maintenance-free gas-insulated switchgear. It is mainly used in power stations, subways, high-rise buildings, industrial and mining enterprises and other power distribution systems to control, protect and monitor the power supply system and load.
