Low-Voltage Draw-out Switchgear

Core low-voltage assembly for efficient power distribution and motor control.

Product Description

GCK low-voltage draw-out switchgear is a low-voltage power distribution assembly used as a power distribution center (PC) and motor control center (MCC) in power plants, substations, industrial plants, high-rise buildings, and similar applications. It is designed for AC 50-60Hz power systems with a rated operating voltage up to 660V and a rated current up to 4000A, enabling power distribution, centralized motor control, and reactive power compensation.

Product Advantages

Highlight

Diverse Functional Units

Drawer units of the same type offer good interchangeability. The door of the functional unit compartment and the operating mechanism of the main circuit switch are interlocked to ensure operational safety.

Highlight

Reliable busbar system

A three-phase five-wire system is adopted. The horizontal busbar is installed at the top of the cabinet. The neutral conductor (N) can be installed either at the top or at the bottom of the cabinet, while the protective earth conductor (PE) is installed at the bottom. The busbar is made of copper, offering high mechanical strength and good heat dissipation.

Highlight

High safety

A mechanical interlock is provided, allowing the door to be opened only when the handle is in the disconnection position, preventing misoperation. Functional unit compartments are separated by metal plates to effectively prevent accident propagation.

Highlight

Reasonable structural design

The basic frame is a modular assembly structure, connected by screws to avoid welding deformation and stress, improving installation accuracy. The mounting holes for the frame and components are modularized, allowing flexible and convenient assembly. Internal structural parts are galvanized, while the external structure is phosphated and then coated with electrostatic epoxy powder, providing corrosion resistance and an attractive appearance.
