Low Voltage Withdraw-type switchgear [ Power Control System ]
Introduction - GCS Low Voltage switchgear (Withdraw-Type)GCS Low Voltage Withdraw-Type switchgear applies to power generation and supply system of three-phase 50Hz AC , rated voltage is 400V(690V), rated current is 4000A and below for the power, power distribution, motor centralized control and electric capacity compensation. It is widely used in power plants, petroleum, chemical industries, metallurgy, textile and high-rise constructions as well as large-scale power plants and petrochemical system which high automation degree and computer interfaces are required. GCS Low Voltage Withdraw-Type switchgear (hereinafter refers to the equipment) is a competitive advanced Switchgear which is designed by two design unions in accordance with the industry authorities, majority of the electricity users and the design department.
GCS Low Voltage switchgear had passed the two departments’ co-chaired identification in July, 1996, Shanghai. It was valued and approved by the manufacturer as well as electricity application departments. Power industries and mechanical industries have jointly issued the Notice About Promotion and Application Related Problems of GCS Low Voltage Withdraw-Type switchgear as safe manufacturing (1997) NO.1 document and heavy machine (1997) NO.1 document. At present, GCS Low Voltage Withdraw-Type switchgear has been widely used by electricity users.
Low Voltage switchgear is widely used in power plants, petroleum, chemical industries, metallurgy, textile and high-rise constructions as well as large-scale power plants and petrochemical system which high automation degree and computer interfaces are required. It is applied to power generation and supply system of three-phase 50(60)Hz AC , rated voltage is 380V(400V), rated current is 4000A and below for the power, power distribution, motor centralized control and electric capacity compensation.
The design of this equipment meets the standards of IEC439-1 Low Voltage Series Switch and Control Equipment , GB7251 Low Voltage Series Switchgear and ZBK36001 Low Voltage Withdraw-type Series Switchgear and so on.
GCS Low Voltage Withdraw-Type switchgear of our company had passed national mandatory product identification.
