Short Description:
The GNRMU series gas insulated switchgear (C-GIS) is a new generation of switch products developed by Xidong Electric with independent intellectual property rights. It uses low-pressure SF6 gas as the insulation medium, vacuum circuit breakers, and three position switches as the main primary components, sealed inside the gas filled compartment. The gas chamber is welded with 3mm thick high-quality stainless steel plate, which is not affected by the environment. It has the characteristics of reliable operation, safety guarantee, compact structural design, small space occupation, maintenance free, and long service life.
