▸ Product Introduction

Product Summary

XGN15-24(SF6) Unit AC Metal-enclosed Ring Network Switchgear (hereinafter referred to as ring network switchgear) adopts advanced foreign technology and meets the demands of domestic and urban network reconstruction. It is a new generation of high-voltage electrical products developed through independent design and development. All the technical performance meets the standards of IEC 62271-200:2003 and GB 3006.

The main switch, operating mechanism, and other components of the ring network switchgear use original ABB equipment or SF1-12 switchgear, which is assembled in China using imported parts. We can also use original imported ABB equipment: SF1 type SF6 circuit breaker or VD4-S type vacuum circuit breaker. Its operation mode can be divided into two types: manual and electric. The cabinet is processed using numerical control machine tools and connected by rivets. Its protection degree is IP3X. It has a reliable mechanical interlock and an operation function for error prevention.

The product has a small volume, light weight, beautiful appearance, easy operation, long life, high parameters, no pollution, and requires minimal maintenance, making it an extremely remarkable product.

XGN15-24(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 an SF6 switch.
