Product Description

Product Overview

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

 

The HCM-40.5 SF6 RMU from Guang Dong Hao Cheng Electric Co., Ltd is a compact medium voltage series designed for efficient power distribution. This RMU features a fully insulated and enclosed design, with the switchgear and main bus sealed in a shell filled with SF6 gas. The SF6 gas provides complete insulation, sealing, expandability, and ease of combination.

 

Each SF6 insulated gas box can be easily expanded on both the left and right sides, allowing for flexible configurations. The bottom of the gas tank is equipped with an explosion-proof channel and diaphragm to effectively prevent damage from high-pressure gas to personnel, cables, and other switchgear in the substation.
