GGD  AC Low Voltage switchgear




1.General  Description:

 

GGD Low-voltage combination switchgear is assembled with modules in the factory and is used in the powering system of AC 50-60Hz and rated working voltage 380V. It meets the relative technical requirement of international standard IEC439-1 and national standard GB7251. The device is applied for power supply system, power plants, substations, industrial mining enterprises, high buildings, airports, stations, terminals, etc, where use AC of 50-60HZ and voltage of 380V, needing functions such as distribution, motors and electrical equipment’s control, start-up, lighting, power conversion, power compensation, and so on.

 

2.Working condition:

1.Ambient temperature;-5----+40

2.Altitude:≤2000m(indoor use)

3.Relative humidity≤95%(when temperature is +20),Maybe there will  be condensation influence because of temperature change,user must consider it.

   4.Switchgear and vertical surface’s gradient is no more than 5%, and whole switchgear must be put parallel and level.

   5.Service environmentshould be avoided fire, explosion risk, serious  pollution, chemical corrosion and violent vibration.User should discuss with supplier while they have special requirements.
