Product Overview

Product Description:

 

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 is designed for efficient and safe power distribution. The switchgear and main bus are sealed in a shell filled with SF6 gas, providing complete insulation and sealing. This RMU is expandable and easy to combine, with each SF6 insulated gas box allowing for arbitrary expansion on both sides. The explosion-proof channel at the bottom of the gas tank is equipped with an explosion-proof diaphragm to effectively prevent damage from high-pressure gas to individuals, cables, and other switchgear in the substation.
