Product Description

 

HXGN17-12 (F) Cubicle (fixed type) AC Metal-enclosed Ring Switchgear

Product Overview

HXGN17-12 (F) cubicle (fixed type) alternating-current metal-enclosed ring main unit (hereinafter referred to as ring main unit) is a new generation of HV product designed and developed independently by our company by adopting overseas advanced technologies combined with the power requirements of our country. It is applicable for three-phase distribution systems of 50Hz and rated voltage 10kV, used for electric energy receiving and distribution in factories and mine, residential districts, high-rise buildings, schools, parks and so on, also can be applied to ring network power supply and terminal power supply. 

All internal components are national advanced products with excellent performances complying with relevant standards, are featured with small size, light weight, simple operation, small operation force, safe operation, convenient maintenance, reliable quality, less floor space, installation against wall is available, free of fire or explosion hazard, etc. Through data analysis and expert appraisal, the technical parameters of our products have reached international advanced level among the similar products.
