Eco-Friendly Gas-Insulated RMU (Lower Isolator)

The Eco-friendly Gas Insulated Ring Main Unit (Lower Isolator) uses high-purity dry air as the insulating gas. All live parts and switches are fully sealed inside a stainless steel welded enclosure, ensuring that internal components are not affected by external environmental conditions. The operating mechanism is treated with a ZnNi alloy surface finish, delivering high reliability, personnel safety, and virtually maintenance-free operation. Standardization and modular design further enhance interchangeability and scalability, facilitating future upgrades and retrofits.
