GCK series switchgear is suitable for primary power distribution in industrial and mining enterprises, three-phase AC frequency 50HZ (rated voltage 380V to 600V) power system and secondary power distribution or control equipment with asynchronous motors as the main control objects.

The GCS type AC low-voltage complete switchgear produced by Dingkai Electric Equipment Co., Ltd. is suitable for power distribution systems in power plants, petroleum, chemical industry, metallurgy, textiles, high-rise buildings and other industries. In large power plants, petrochemical systems and other places with a high degree of automation that require computer interfaces, it is used as a power generation and power supply system with a three-phase AC frequency of 50 (60) Hz, a rated operating voltage of 400V, 660V, and a rated current of 5000A and below. A complete set of low-voltage power distribution devices used in power distribution, motor centralized control, and reactive power compensation. The design of the device complies with the following standards: IEC439-1 "Low-voltage complete switchgear and control equipment" GB7251 "Low-voltage complete switchgear".

Electric box-type substations (hereinafter referred to as box-type substations) absorb the advantages of foreign box-type substations and adopt new processes, advanced electrical components and high- and low-voltage automation technologies to meet the requirements of my country's power grid automation and power departments. Box-type substations are composed of high-voltage switchgear, distribution transformers, low-voltage switchgear, energy metering equipment and power compensation devices assembled in one or several boxes. Intelligent modules are installed on the high-voltage and low-voltage sides to meet the automation requirements in the distribution network and realize remote control, telemetry, remote signaling, remote adjustment, and computer system management.
