Audited Supplier Introducing the HCM-12 (24) SF6 fully insulated, fully enclosed, common box compact medium voltage series ring main unit (RMU) by Guang Dong Hao Cheng Electric Co., Ltd. This RMU features switchgear and main bus sealed in a shell filled with SF6 gas, providing complete insulation, sealing, expandability, and ease of combination. Each SF6 insulated gas box can be expanded on both the left and right sides, offering flexibility in configuration. The explosion-proof channel at the bottom of the gas tank is equipped with an explosion-proof diaphragm to effectively prevent high-pressure gas damage to individuals, cables, and other switchgear in the substation.
