The production's switchgear assemblies is made up of center of power distributioin of electricity(PC) and center of control electromotor(MCC) etc. it is the same with place which alternating 50, 60Hz and rated work-voltage 380V, rated insulation-voltage 660V, such as power plant, transformer substation, industry and mining, pile and etc. It is the same with low-voltage distribution of indoor, center of controlling electromotor, lighting and compensate. The production had passed authentication of CCC, measure up GB7251.1, IEC439-1 and etc.
Features of production:
The production has stronger capability of disjunction, its rated short-time withstand current is 50KA(GGD3). It has strongpoint of flexible scheme of circuit, ease to fix, practicality, original configuration and so on. It is one of classical works in China. It makes figure of armor plate, deal surface with static-plastic sprayer, goodlooking, durable goods, good defend performance(IP20, IP30); component of main circuit in cabinet is fixture, run it in front, safety and credibility, can maintenance in front or at back
