HXGN15-12 Medium Voltage AC Metal Enclosed RMU Ring Main Unit Switchgear panels 10KV 11KV 12KV 630A 1250A with VCB Breaker 

The HXGN15 AC Metal-enclosed Ring Main Unit Switchgear (hereinafter referred to as "ring main unit") is a new product designed and developed by Denggao Electric co. from overseas with advanced latest techniques. The technical indicators of the product reach standards of  IEC62271-200 and  GB3906. The product is characterized by small volume, light weight, operation flexibility, maintenance convenience, and quality stability & reliability, and it comes out with perfect interlock protection functions and IP3X protection grade, so it is an ideal product for mains grid reconstruction. The product is mainly applicable to a 50Hz three-phase AC network for receiving and distributing energy.

Mainly applicable in urban power grid construction and renovation project. industrial and mining enterprises.high-rise buildings and communal facilities. For power distribution controlling and protecting electric equipment as the loop power supply unit or terminal equipment. It also can be installed in a preloaded substation
 

Feature:

Uses the SF6 load switch and load switch-fuse combination as the main switch. Equipped with vacuum load switch and spring operating mechanism which can be operated by hand or electric. Earthing switches and insulating switches are equipped with a hand operating mechanism. With small volume and high security

1. Many years ring main unit manufacturer 
2. Easy installation 
3. Less maintenance 
4. Safe and upgradeable
