Product Introduction

General

This RMU switchgear using SF6 as an arc extinguishing medium with double open contacts, 3 working-position and rotating contact which placed in an epoxy resin shell of a reinforced structure. Each gas box must pass helium leak detection before being filled with 0.045Mpa SF6 (Inspect any leakage to ensure can be installed vertically or horizontally). The classic installation is "horizontal", that is, install steel partitions between the cable compartment and the busbar compartment. That makes the interval between the busbar and the cable joint the most stringent safety requirements.
