high-rise buildings and other civil and industrial and mining
enterprises of power distribution system, in large power plants,
petrochemical, telecommunication system, etc. A high degree of
automation, and computer interface, as the motor
centralized-control hair, power supply system of power
distribution, low-voltage distribution of reactive power
compensation device.
Endeavoring to provide customers with best service, AI will make
the mission "Distributing green energy for better world" come true.
Type GCS low-voltage withdrawable type switchgear is a blend of the other advantages of low voltage products and the development of advanced products, applicable to power plants, petrochemical industry, metallurgy, telecommunications, light industry, textile, high-rise buildings and other civil and industrial and mining enterprises of power distribution system, in large power plants, petrochemical, telecommunication system, etc. A high degree of automation, and computer interface, as the motor centralized-control hair, power supply system of power distribution, low-voltage distribution of reactive power compensation device.
GCS switchgear is suitable for power supply and distribution systems with AC 50Hz, rated working voltage 690V or less and rated current of main bus up to 4000A. The product adopts 8MF open section steel, which makes the frame assembly flexible and convenient, and can form standard units such as protection, operation, conversion, control, regulation, measurement and indication. The maximum number of functional units of a single drawer cabinet can be up to 22, which fully takes into account the need of centralized control of motors in large single capacity power plants, petrochemical systems and other industries. The specific heat capacity of the adapter is high, which reduces the additional temperature rise caused by the temperature rise of the adapter to the connectors, cables and partitions. The parallel arrangement of buses makes the equipment have good dynamic and thermal stability, can withstand large short-circuit current impact, and has the characteristics of high insulation strength, good self-extinguishing performance, unique structure and strong adaptability to the bus. The corresponding protection level can be selected according to the different requirements of the working environment.

1. Indoor altitude above sea level: Maximum installation altitude: 2000m
2. Ambient air temperature: -5℃~+40℃ and the average temperature should not
exceed +35℃ in 24h
3. Relative humidity should not exceed 50% at max temperature +40℃. Higher
relative humidity is allowed at lower temperature. Ex. 90% at +20℃. But in view of
the temperature change, it is possible that moderate dews will produce casually.
4. No fire, explosion danger, serious pollution, chemical corrosion and severe vibration
5. Installation gradient not exceed 5°
6. This product is suitable for the following temperature transportation storage: -25℃ ~+55℃ 24h, in a short period of time (no more than 24hours) not more than+70℃.
