XGN75-12 gas insulated metal enclosed switchgear

XGN75-12 indoor gas-insulated metal-enclosed switchgear (hereinafter referred to as XGN75-12 inflatable cabinet) is a high-tech product independently developed by Tianan Electric that adopts vacuum arc extinguishing and SF6 gas insulation technology. The technical level has reached the leading domestic and international level. Advanced level. All high-voltage live components of the product 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-operated vacuum circuit breaker with three stations. The isolation grounding switch of the product 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.
