Profile of this metal enclosed switchgear:
C-GIS -40.5 indoor gas insulated metal-enclosed switchgear (C-GIS), hereinafter referred to as C-GIS-40.5 inflatable cabinet.
All high-voltage live components of the C-GIS inflatable cabinet are sealed in a stainless steel box (IP67) filled with SF6 gas of lower pressure (0.03～0.05MPa gauge pressure, 20℃).
The main switch adopts a spring operating mechanism vacuum circuit breaker with three
The isolation grounding switch of the workstation has stable insulation performance,
and is especially suitable for harsh environments such as high altitude, severe cold, humidity, and pollution.
Due to the small footprint of the product, it can be used in places with tight land (such as rail transit).
