An overview of the

GCS low-voltage withdrawable switchgear is suitable for the power plant, petroleum, chemical industry, metallurgy, textile, high-rise building distribution system. In large power plants, petrochemical system, such as high degree of automation, and computer interface, a three-phase ac frequency 50 Hz (60), rated voltage is 380 v, 660 v), rated current 4000 a, power supply system of power distribution and motor under centralized control, reactive power compensation using low-voltage power distribution equipment. Products comply with it - 1 "low-voltage complete switch equipment and control equipment", GB7251 "low-voltage complete switch equipment", ZBK36001 standards such as the "low voltage draw-out switchgear.
