Product Description
A complete low-voltage switchgear with withdrawable elements of the GCK type (hereinafter referred to as the “switching device”) is intended for use in electrical systems with a rated operating voltage of 380 V, in three-phase four-wire and three-phase five-wire AC systems for receiving electricity, its distribution, reactive power compensation, electricity metering, lighting and centralized control of electric motors at power plants, substations, industrial and mining enterprises and in high-rise buildings.
GCK low-voltage withdrawable cabinet is a low-voltage switchgear, widely used in power plants, substations, industrial and mining plants, high-rise buildings and other fields. Designed for operation in AC electrical networks with a frequency of 50 (60) Hz, rated operating voltage up to 660 V and rated current up to 4000 A for power distribution, centralized control of electric motors, reactive power compensation and other functions.
Features
1.High reliability and safety: Meets the requirements of the state standard GB/T7251.12-2013, international standard IEC439 and others. Has high breaking capacity and dynamic resistance. The housing is divided by metal partitions into a busbar compartment, a functional block compartment and a cable compartment. The degree of protection can reach from IP30 to IP54, which effectively prevents the spread of short circuit arc and ensures safe operation.
2.Modularity and flexibility: The frame is made of G-section profiles, weldless design, modular design (E = 20 mm or 25 mm). Various standard sizes of withdrawable units are supported: 1/2 unit, 1 unit, 3/2 unit and others. One cabinet can accommodate up to 18 circuits. Provides flexible combination of power distribution (PC) and motor control (MCC) functions.
Ease of maintenance and operation: Withdrawable units are equipped with a four-position control mechanism (“working”, “testing”, “disconnected”, “isolated”), which has a mechanical interlock with a circuit breaker handle that prevents erroneous operations. High-strength nylon guides provide smooth insertion and removal, allowing for quick maintenance and replacement of units.
3.Highly adaptable to environmental conditions: The body is made of galvanized steel and flame-retardant engineering plastic. The surface is treated with an anti-corrosion coating, which allows the device to be used in conditions of high temperature, high humidity and aggressive industrial environments. Internal air channels are optimized to ensure controlled temperature rise during long-term operation.
4. Excellent technical parameters: The short-circuit current of horizontal busbars can reach 100 kA, the peak short-circuit current of vertical busbars can reach 176 kA. The maximum power of controlled electric motors is up to 320 kW. Meets the requirements of industrial power distribution with high loads and demanding requirements.
5. In general, GCK low voltage cabinet, with its advantages such as advanced design, flexible layout, safety, reliability and easy maintenance, has become the main choice in modern industrial power distribution systems.
