  • Number: Transmission and Distribution 02

Overview
XGN15-12/24 cell-type modular sulfur hexafluoride RMU is a kind of compact and open-ended metal-enclosed switchgear equipped with the new generation of sulfur hexafluoride switch as its main switch and the air-insulated entire cabinet suitable for distribution automation. Featured by simple structure, flexible operation, reliable interlock, and easy installation, it can provide satisfactory technical solutions for diverse applications and different user requirements.
It can fully meet the changing market after adoption of sensor technology and latest power protection relay, plus advanced technical performance and lightweight flexible equipment.
ABB original SFG-type SF load switches or domestic FLN48, FLN36 SF load switches are adopted as main switches. And ABB original VD4/S or HD4/S circuit breakers can also be equipped according to user needs.

Main Applications
XGN15-12/24 cell-type sulfur hexafluoride RMU is applied to power systems of AC 50Hz under 12kV, and widely used in the industrial and civil cable ring networks and power supply terminal engineering.
It’s especially suitable for the following places: transformer substations in urban residential areas, small secondary substations, switching stations, industrial and mining enterprises, shopping malls, airports, subways, wind power substations, hospitals, stadiums, railways, tunnels, etc.
