GGD Type AC Low Voltage Distribution Cabinet
GGD type AC low voltage distribution cabinet
Introduction and usage
GGD type AC low voltage distribution cabinet is suitable for power plants, substations,factories,mine enterprises whose distribution system is with 50HZ AC,to 3150A rated working current, used for power change,distribution and control of power, lighting and power distribution equipments.
GGD AC low voltage distribution cabinet is a kind of new type low-voltage distribution cabinet, designed based on the requirements of the Department of Energy in charge of the higher level, the majority of electricity users and design department, and with principles of safe, economic, rational and reliable. It is with these characteristics of high breaking capacity, good dynamic thermal stability, flexible electrical program, convenient combination methods, series, practical, novel structure, high level of protection, can be treated as a replacement product of low voltage switchgear assemblies.
GGD type AC low voltage distribution cabinet meets the standard of IEC43Low-voltage switchgear and control gear, GB7251Low-voltage switchgear assembliesOperational conditions
1, surrounding air temperature not more than +40°C, not less than -5°C, average temperature over 24hs cannot more than +35°C
2, installed in indoor, altitude not higher than 2000m
3, surrounding air relative humidity at the highest temperature of + 40 ℃ not more than 50%, at a lower temperature allows a greater relatively humidity( for example, temperature is + 20 ℃, humidity can be 90%), should consider the influence of condensation caused occasionally due to the temperature change.
4,the inclination between cabinet and vertical plane not exceed 5%
5, cabinet need be installed in the place without severe vibration and shock and where is insufficient to corrode electrical components.
6,users can consult with manufacturers if have special request.
