GCS  LV Withdrawable switchgear




1.General  Description:

 

The product is designed to meet the requirements of the electrical users with high technical performances. It adapts the development and  needs of electricity market and also competes with the existing low-voltage switchgears. At present the product has been used widely in power plants, petroleum, chemicals, metallurgy, textiles and high-rise architecture, and the distribution systems in other industries. The product services in the power system of generation   and supply of rated voltage of 380V (400),(600), rated current of 4000A, below three-phase AC, frequency of 50(60) HZ, and the following of the electricity supply system of distribution, motor centralized control and reactive power compensation. The product meets the standards of GB7251, JB/T9661 and IEC60439-1.

 

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.
