Types of High Voltage Switch Cabinet

HXGN-12 Ring network switchgear equipment

HXGN-12 fixed AC metal closed ring network switchgear (Also name as ring network cabinet switchgear), suitable for industrial and mining enterprises, residential quarters, high-rise buildings and school parks and other power distribution systems. as an indoor AC three-phase 12KV, 50HZ ring network power supply unit and terminal power distribution equipment. It can open or close the rated load current and the no-load current of the transformer. and open or close the overhead line, cable line or capacitive current of a certain distance. The load switch fuse combination electrical cabinet can break the rated short-circuit current at one time. In the power system. it is used for the protection of power distribution equipment, the distribution and control of electric energy, and has a perfect "five prevention" locking function.

XGN-12 box type fixed AC metal enclosed switchgear

XGN-12 box-type fixed-type AC metal-enclosed switchgear (hereinafter referred to as switchgear), used in 12KV and below three-phase AC 50Hz system to receive and distribute electric energy. especially suitable for frequent operations. The system is a single bus (single bus with bypass and double bus structure can be derived).

XGN-12 box-type fixed metal-enclosed switchgear is a prototype product derived from ordinary switchgear suitable for use in high-altitude areas. and has a complete "five-proof" locking function.

GG-1A (F) type fixed high voltage switch cabinet
