Audited Supplier Introducing the HCM-40.5 SF6 Fully Insulated Ring Main Unit (RMU)
The HCM-40.5 SF6 RMU from Guang Dong Hao Cheng Electric Co., Ltd is a compact medium voltage series designed for efficiency and safety. The switchgear and main bus are enclosed in a fully insulated SF6 gas-filled shell, providing complete insulation and sealing. This RMU is expandable and easy to combine, with each SF6 insulated gas box allowing for flexible expansion on both sides.
For added safety, an explosion-proof channel at the bottom of the gas tank features an explosion-proof diaphragm, effectively preventing high-pressure gas damage to individuals, cables, and other switchgear in the substation.
