Product Description

Summary:

HXGN15-12 series of products is consist of standard functional units, which are completed by the factory processing, using technologically advanced FLN36-12 load 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 24 kv power supply system.

Convenient installation: small cabinet volume and light weight, so that users can more easily checked and installed, the device can be based on user requirements knot to form a complete line of solutions, also can be optional intelligent control unit, to realize intelligent control unit. Standardized design makes this product be the most ideal choice for user to modify and extend the substation program.

Simple operation: each cabinet is equipped with a circuit line diagram and analog display( show switch internal components ). The operating mechanism has chain board, can ensure the rota-tion direction of handle and the correct operation of device, to prevent misoper ation. Moreover, provide the safe simple operation of step instructions on the door.
