CDMNS1 low-voltage draw-out type switch cabinet

CDMNS1 low-voltage draw-out type switch cabinet("Switch Cabinet") is developed by our company with reference to the MNS low-volgage switch cabinet produced by Swiss ABB company. The switch cabinet,composed of standardized,serialized modules,is mosrt advanced in China.the secure mechanic inerlock mechanism for drawer ensures safety and reiliability.

The Switch Cabinet, applicable to three-phase five-wire power supply system whose fequency ,rated insulation voltage,working voltage,and rated current are respectively50(60)Hz,380(400)V, 660V,5000A or weaker, may be used in power stations substations,factories,mines,building,hotels, airports ,harbors, broadcast televisions to control the aquipments generating, transmitting, distribution, exchanging or consuming power, and to offer reactive compensation,by means of capacitance compensation cabinet, for main bus-bar.
