XGN15-12/24 SF6 Ring Main Unit, Compact Metal-Enclosed Switchgear, 12kV 24kV

Product Description

1. Product Overview

The JRH XGN15-12/24 SF6 Ring Main Unit (RMU) is a new generation of air-insulated, compact metal-enclosed switchgear centered around an SF6 load break switch. Designed for 3-phase AC 50Hz power distribution systems with rated voltages of 12kV and 24kV, this switchgear is built for receiving and distributing electricity in industrial/civil cable ring networks and terminal power supply systems. Engineered for modern distribution automation, the XGN15 cabinet features a sleek appearance, simple architecture, compact footprint, flexible operation, and reliable interlocking mechanisms. It is ideal for urban residential distribution, secondary substations, switching stations, industrial enterprises, commercial complexes, airports, subways, tunnels, and wind power installations.
