Type GCS low-voltage withdrawable switchgear is by the national electric power industry, machinery industry according to the department in charge of industry, the majority of power users and design units developed in accordance with the requirements of design conditions, with high technical performance indicators and can meet the need of electric power market development and can compete with the introduction of existing product draw-out switch cabinet, the use of power by manufacturing units and departments of recognition and affirmation.
It can be used in power plants, substations, petrochemical departments, industrial and mining enterprises, metallurgical and textile enterprises, high-rise buildings and other places with high degree of automation and requiring computer interface. It is a complete set of low-voltage supporting devices for distribution, centralized control of motors and reactive power compensation in power supply system with three-phase ac frequency of 50Hz, rated working voltage of 380V, rated working current of 4000A and below.
The protection level reaches IP30.
The cabinet structure is assembled by KS profile (KB profile can also be used), the standard modulus is 20mm, the cabinet body after acid washing phosphating electrostatic spraying. Internal partition, drawer galvanized passivation treatment. The function rooms are separated from each other, which are divided into function unit room, bus room and cable room. The function of each chamber is relatively independent, which can prevent touching live parts of adjacent functional units and limit the expansion of faults.
