It\'s the largest manufacture for LV switchgear enclosure all over China. At present, Wecome has a total asset of around RMB 1.7 billion Yuan, 210,000 Square meters factory buildings, over 3000 staff and has separately sets up hi-tech industrial parks in Wenzhou, Lishui, Tianjin and Chengdu. It has 10 wholly-funded subsidiaries, more than 1200 cooperative enterprises and 60 sales agencies.
We are pursuing to be the leader of electrical enclosures in China and striving for the development of electric power industry!

XGN2-12 series cubicle is with several new designs and awarded patent. It\'s suitable for single busbar,double busbar and bypass busbar system.It\'s used for power acceptance and distribution, circuit control, protection and detection in power plants,transfomer substations, industrial and mining establishments, etc..

Main characteristics:
 

• Width for 1100mm,1200mm,different size cubicle for option.
• Meterial optional with galvanized steel or Alu-zinc coated steel.
• Reliable five-safety interlock device with national utility model patents.More enhanced personnel protection.
• CB compartment is installed with pressure release channel in case of internal arc.
• Compatible with PT handcart,metering handcart,fusing handcart,isolating handcart,etc..
• Inside is mounted with heater to avoid condensation and corrosion.
• Earthing switch can work with electric operating mechanism to make the remote control.
• Enclosure protection degree is P3X,when handcart door open,each compartment pretection degree is IP2X.

Applicable Standards:
 

• GB3906-97 “AC metal closed switchgear 3-35kV”
