GCK low voltage withdrawable switchgear
GCK low-voltage withdrawable switchgear is suitable for power distribution systems in power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries. In large-scale power plants, petrochemical systems and other places with high degree of automation, requiring interface with computers, as a three-phase AC frequency of 50 (60) Hz, rated voltage of 380V (400V), (660V), rated current of 4000A and below, power generation and power supply system in the power distribution, centralized control of motors, reactive power compensation of the use of low-voltage complete power distribution equipment.
Product Features
-
- Suitable for power distribution systems in power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries.
-
- The main frame assembly is designed in two forms, fully assembled structure and partial (side frame and beam) welded structure, for users to choose.
-
- Each functional room of the device is isolated from each other, and its compartments are divided into functional unit room, busbar room and cable room. The role of each chamber is relatively independent.
-
- The design of the cable compartment makes it easy to enter and exit the cable up and down.
