Detailed description

XGN15-12 12kV High voltage eletrical switchgear/sf6 ring main unit switchgear

Product Description

XGN15-12(SF6) Unit AC Metal-enclosed Ring Network Switchgear (hereinafter called rinf network switchgear) adopts foreign advanced technology and accords to the demands of the domestic rural and urban network reconstruction. And it is a new generation of high voltage electrical product through independent design and development. All the technical performance meets the standards of IEC62271-200, 2003 and GB3906.

The main switch, operating mechanism and other components of the ring network switchgear adopt original imported ABB equipments or SFL-12 switch equipment which uses original imported parts to assemble  in China. We can also use original imported ABB equipment: SFL type---SF6, circuit breaker or VD4-S type vacuum circuit breaker. Its operation mode can be divided into two kinds: manual and electric.

Cabinet is processed by numerical control machine tool and connected by rivets. Its protection degree is IP3X. It has reliable mechanical interlock and operation function of error preventing. The product has small volume, light weight, beautiful appearance, easy operation, long life, high parameter, no pollution and less maintenance as its extremely remarkable features.

XGN15-12(SF6) Unit AC Metal-enclosed ring network switchgear is used in the power system of AC 50Hz 12kV to receive and distribute power. The main switch in the cabinet is SF6 switch.

Environmental Conditions

1)Suitable Temperature: -15℃~ +40℃

2)Suitable Altitude:≤1000m

3)Relative Humidity: Daily mean≤95%, monthly mean≤90%

4)Gradation of Earthquake Damage:≤Level 8
