Case

XGN49 series indoor gas insulated metal-enclosed switchgear (C-GIS), hereinafter referred to as XGN49-40.5(24) inflatable cabinet, is a high-tech product independently developed by Tianan Electric that uses vacuum arc extinguishing and SF6 gas insulation technology. The level has reached the domestic leading and international advanced level.
All high-voltage live components of the XGN49 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).
