The core unit of Enerswit+ 40.5kV series SF6 gas insulated RMU uses patented self-energized load switch, vacuum circuit breaker with ultra-low resistance and primary live parts, which are sealed in a stainless steel air tank fully filled with SF6 to isolate with the outside, ensuring that the switchgear and all live parts in the air tank will not be affected by the outside environment. This exempts the unit from maintenance, improves the reliability of power supply, enhances personal safety and meets the needs of economic and reliable operation.
