Audited Supplier Product Description:
The HCM-40.5 SF6 Ring Main Unit (RMU) by Guang Dong Hao Cheng Electric Co., Ltd is a fully insulated and enclosed medium voltage switchgear solution. The switchgear and main bus are 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. The bottom of the gas tank features an explosion-proof channel with a diaphragm to effectively prevent high-pressure gas damage to individuals, cables, and other switchgear in the substation.
