Product Introduction

XGN2-12 cubicle fixed metal-enclosed switchgear (hereinafter referred to as switchgear) is used in three-phase AC 50Hz system with rated voltage of 3.6KV, 7.2KV and 12KV for receiving and distributing electric power. The switchgear is particularly suitable for indoor occasions of frequent operation. Its busbar system is single busbar, from which the single busbar with bypass and double busbar structure are derived.

The switchgear complies with the national standards, such as GB 3906 “3.6~40.5KV AC Metal-enclosed Switchgear and Control Equipment” and DL 404-1997 “Ordering Technical Requirements for Indoor AC HV Switchgear”.


Product Features

1. Its housing is assembled with C-shaped steel, and the cabinet is divided into four parts, namely main busbar compartment, instrument compartment, circuit breaker compartment and cable compartment. Those compartments are separated by metal partitions.

2. The master switch uses ZN28-12 or VS1-12 series vacuum circuit breaker(VCB), and disconnector adopts GN30S-12 or GN22-12 series VCB. The transformer is fully insulated with higher safety margin.

3. The switchgear has reliable five-anti interlocking device.
