GCS

Product Description

GCS/GCK low-voltage withdrawable switchgear is widely used in power station, substation, industrial and mining enterprises and high-rise building power distribution center PC and motor control center GCS, as a low voltage complete power distribution equipment for AC 50-60HZ, rated voltage under 660V and rated current under 4000A, power distribution in the power supply system, centralized control of motors and reactive power compensation. Low voltage power distribution unit for reactive power compensation. It is used as a transformer, feeder or motor for low-voltage distribution system in three-phase three-wire or three-phase four-wire system. GCS/GCK low-voltage withdrawable switchgear has increased capacity and mechanical strength on the basis of keeping the electrical performance higher than similar products, and has advanced structure, beautiful appearance, high protection level, safety and reliablility, easy for maintenance and other characteristics. It can be used as the replacement product of low-voltage switchgear.

Features

1. The whole cabinet adopts assembly type combination structure, modular hole installation, strong generality of parts, good applicability and high degree of standardization. 2. The upper part of the cabinet is the busbar room, the front part is the electrical room, and the rear part is the cable incoming and outgoing room. Each room is isolated by a steel plate or an insulating board to ensure safety. 3. The door of the drawer compartment of the GCS cabinet is equipped with a mechanically interlocked with the operating handle of the circuit breaker or disconnection switch, so that the door can only be opened when the handle is in the breaking position. 4. The incoming switch, contact switch and the drawer of the GCS cabinet have three positions: on position, test position and off position. 5. The top of the switch cabinet can be equipped with a busbar bridge according to the power needs.
