SF6 Gas Insulated Ring Main Unit 12 KV Metal - Enclosure Switchgear
Overview
HXGT6 (XGN58)-12 SF6 Ring Main Unit Switchgear (hereinafter referred to as “RMU”) is designed and developed by our company based on actual power supply situation of our nation. It is a new generation indoor 10kV MV electric appliance, and can be applied in city grid transformation and construction, the product is subjected to type test and commissioning examination, the performance indexes meet the requirements of IEC 298 “AC Metal Closed Switchgear”. It processes the advantages of small volume, low weight, simple operation, safe use, high reliability without influencing by environment and weather and maintenance-free.
The switchgear is a kind of composite apparatus which seals all main circuits in a metal enclosure and take SF6 gas as arc extinguishing and insulation medium. It is suitable for ring network power supply and double radiates power supply in 10kV MV power supply network. It is also used in terminal power supply. Due to the use of ring network power supply increases the reliability of power supply, it is specially used in mineral plants, residence area, schools, parks, and so on for power distribution and controlling. In addition, because of its convenient connection and installation, small volume, it is also used in the substation as high voltage equipment on primary side.
