GCS 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 power plants, petrochemical systems and other places with a high degree of automation and requiring interface with computers, the three-phase AC frequency is 50(60)Hz, the rated working voltage is 380V(400V), (660V), and the rated current is 4000A and below. It is a low-voltage complete power distribution device used for power distribution in power generation and power supply systems, centralized control of motors, and reactive power compensation.
