Enerswit+ 40.5kV Series SF6 Gas-Insulated Switchgear

Description

The core unit of the Enerswit+ 40.5kV Series SF6 Gas-Insulated Switchgear integrates an original self-energy load switch (combining pressure-blown arc extinction and gas-generating arc extinction) and an ultra-low resistance vacuum circuit breaker, both based on mature high-voltage GIS technology. Primary live components are enclosed in a stainless steel gas tank filled with SF6 gas, isolated from the external environment. This ensures that the switchgear and all primary live parts inside the gas tank are not affected by changes in the external environment, achieving maintenance-free operation of the equipment, improving power supply reliability, enhancing personnel safety, and meeting the requirements of economical and stable operation.

The compact and efficient structural design of the Enerswit+ 40.5kV Series is protected by utility model patents and invention patents, perfectly integrating compactness, performance, and economy.
