Product Description

Product Overview

Introducing the HCM-40.5 SF6 Fully Insulated Ring Main Unit (RMU)

 

The HCM-40.5 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 efficiency and safety. 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, offering flexibility in configuration. The explosion-proof channel at the bottom of the gas tank features an explosion-proof diaphragm, effectively protecting against high-pressure gas damage to individuals, cables, and other switchgear in the substation.
