Advantages & Features
Working Principle
GCK low voltage draw out switch cabinet: applicable to power plants, substations, industrial and mining enterprises and other power users as the power system with AC 50Hz, maximum working voltage up to 660V and maximum working current up to 4000A. It is used for power distribution, motor control and other power distribution equipment for power conversion and distribution control.
GCS low voltage draw out switchgear: suitable for power distribution system in power plant, petroleum, metallurgy, textile, chemical industry, high-rise building and other industries. In large power plants, petrochemical systems and other places with high degree of automation and requiring computer interface, it is used as a complete set of low-voltage power distribution devices for power generation and supply systems with three-phase AC frequency of 50Hz, rated working voltage of 400V and rated current of 4000A and below, power distribution in motor system, centralized control of electric machines and reactive power compensation.
Xgn2-12 box type: it is suitable for receiving and distributing electric energy in the power system with rated voltage of 3.6 ~ 12kV, three-phase AC 50Hz and rated circuit of 630 ~ 4000A. It is especially suitable for frequent operation.
