XGN15-12 AC metal ring network switchgear

• Expandable SF6 ring main unit can be combined freely, with a small volume, safe and reliable.

• Using SF6 gas insulation and arc extinguishing medium, the constant magnetic field rotary arc extinguishing method makes it have strong arc extinguishing ability, good breaking performance, low overvoltage, long electrical life, and maintenance free arc extinguishing chamber.

• Adopting SFG load switch and load switch fuse combination electrical device, it has three station function, perfect sealing, reliable operation machinery and locking..

• Grounding switch has short-circuit closing capability.

• Cabinet is formed by stamping and bending aluminum zinc coated plates, and assembled in a plug-in manner, which is sturdy and reliable.

Product Introduction

XGN15-12 AC metal ring main switch cabinet is a metal enclosed ring main switch equipment with SF6 load switch as the core component and air insulation throughout the cabinet. This device is suitable for power systems with three-phase AC 50Hz and rated voltage of 12kV. It is widely used in urban residential areas, small secondary substations, switch stations, box type substations, shopping malls, airports, subways, wind power generation, hospitals, sports venues, railways, bridges, tunnels and other places.
