Product Description

Summary:

HXGN15-12/24 series of products is consist of standard functional units, which are completed by the factory processing, using technologically advanced FLN36-12/24 load break switch, using superior performance of SF6 gas as the arc extinction insulating medium. The cabinet has advantages of small volume, reasonable and compact, convenient installation, simple operation, safe and stable operation,which has been widely recognized in the 10KV or 24KV power supply system.

Load switch and earthing switch adopts obstacles chain, between of grounding switch and the door adopts mandatory chain. Follow these steps can realize the automatic chain: shut the doors, open the grounding switch, close load switch, the separate operation mode effectively avoid misoperation.
