Audited Supplier HCM-40.5 SF6 Fully Insulated Ring Main Unit
Introducing the HCM-40.5 SF6 fully insulated, fully enclosed ring main unit (RMU) from Guang Dong Hao Cheng Electric Co., Ltd. This compact medium voltage series RMU features a switchgear and main bus sealed in a shell filled with SF6 gas. The SF6 gas is fully insulated, fully sealed, expandable, and easy to combine. Each SF6 insulated gas box can be expanded on both the left and right sides, providing flexibility in configuration. The explosion-proof channel at the bottom of the gas tank is equipped with an explosion-proof diaphragm, effectively preventing damage from high-pressure gas to individuals, cables, and other switchgear in the substation.
