SF6 RMU
The isolated gas distribution unit (RG-17.5kV SF6 RMU) is an innovative
and reliable solution for electrical power distribution. It relies on a patented rotary
load switch and a vacuum circuit breaker, ensuring high performance and complete
safety. All primary live parts are hermetically sealed inside a stainless steel tank
filled with SF6 gas, completely isolating them from the external environment. This
design makes maintenance unnecessary, thereby enhancing the reliability of the
power grid and improving safety levels.
Key Features & Benefits
