III. Structural characteristics
The basic cabinet frame of this series of products is a combination assembly structure. All structural components of the cabinet frame are connected to each other by screws to form a basic frame. Then, doors, baffles, partitions, drawers, installation brackets, busbars, and electrical components are added as needed to assemble a complete switchgear. This cabinet has the following characteristics:
The frame is made of shaped steel, positioned using three-dimensional angle plates, and bolted to a non welded structure to avoid welding deformation and stress, thereby improving installation accuracy.
The installation holes of the frame and components vary according to the modulus E=20mm.
The internal structural components are treated with galvanizing. After external acid washing and phosphating treatment, electrostatic epoxy powder coating is used.

At Jihui Electric Group Co., Ltd., we focus on developing and manufacturing reliable medium and Low voltage power distribution equipment for global customers. Our GCK low-voltage withdrawable switchgear is one of our widely used low voltage solutions, designed for safe power distribution, motor control, and electrical management in industrial and commercial applications.
With years of experience in the electrical equipment industry, we understand that customers need more than just a standard cabinet. They need stable operation, easy maintenance, flexible configuration, and long service life. That is why our GCK low voltage switchgear combines practical design, proven manufacturing processes, and strict quality control to meet different project requirements.
Our GCK series low voltage withdrawable switchgear is designed according to modern power distribution needs. It provides a safe and organized solution for receiving power, distributing electricity, controlling motors, and protecting electrical systems. The withdrawable structure allows operators to quickly remove and replace functional units, reducing maintenance time and improving system availability.
As a manufacturer located in Yueqing Economic Development Zone, China, we provide complete services including product design, production, inspection, export packaging, and technical support. Our factory follows ISO9001 quality management standards, ISO14001 environmental management requirements, and ISO45001 occupational health and safety systems to ensure consistent product quality.
GCK low-voltage withdrawable switchgear is a type of low voltage electrical distribution cabinet used in power distribution systems up to 400V or 690V class applications. It integrates circuit breakers, contactors, protection devices, control components, and busbar systems inside a metal enclosure.
The main feature of this switchgear is the withdrawable design. Unlike fixed electrical cabinets where components are permanently installed, the functional units inside GCK cabinets can be pulled out, inspected, repaired, or replaced without completely dismantling the entire system.
For factories, power plants, infrastructure projects, and commercial buildings, this design brings practical benefits. When a single unit needs maintenance, engineers can handle the work faster while keeping other parts of the electrical system operating normally.
Our GCK low voltage withdrawable switchgear is commonly used as:
Main low voltage distribution equipment
Motor control center (MCC) switchgear
Power distribution cabinet for industrial plants
Electrical control cabinet for automation systems
Low voltage power management equipment for infrastructure projects
The working principle of our GCK withdrawable switchgear is based on safe power receiving, distribution, control, and protection. Electrical power enters the cabinet through the incoming unit and is transferred through copper busbars to different functional compartments.
Each withdrawable unit contains electrical components according to customer requirements. These units can include molded case circuit breakers, contactors, thermal overload relays, control modules, measurement devices, and protection equipment.
During normal operation, the withdrawable unit is connected to the main power system through reliable plug-in contacts. When maintenance is required, operators can move the unit to an isolated position, disconnecting the electrical connection while maintaining safe working conditions.
The cabinet structure normally includes separate areas for:
Busbar compartment for power transmission
Functional unit compartment for control equipment
Cable connection compartment
Control wiring area
This separated structure improves electrical safety and reduces the risk of accidental contact between operators and live components.
The withdrawable design is one of the most important advantages of GCK low voltage switchgear. Different functional units can be configured according to project requirements. Customers can select different drawer sizes, protection devices, and control functions based on their electrical systems.
For large industrial projects, this flexibility makes future expansion easier. When production capacity increases, additional withdrawable units can be added without replacing the complete switchgear system.
Safety is always the first consideration in power distribution equipment. Our GCK switchgear uses a metal enclosed structure and reliable insulation design to improve protection performance.
The cabinet provides protection against electrical faults such as overload, short circuit, and abnormal current conditions. Proper internal separation helps reduce operational risks and supports safer maintenance work.
In many industrial environments, stopping production because of electrical maintenance can create significant losses. The withdrawable structure helps reduce downtime because maintenance personnel can quickly replace or inspect individual units.
Compared with traditional fixed cabinets, GCK low-voltage withdrawable switchgear offers better convenience for daily operation and equipment management.
Every project has different requirements. Some customers need motor control functions, while others need power distribution and monitoring systems. Our GCK low voltage switchgear can be customized according to voltage level, current rating, installation environment, and control requirements.
We provide solutions for:
Industrial production lines
Manufacturing facilities
Energy projects
Commercial buildings
Transportation infrastructure
Public utility facilities
When selecting low voltage distribution equipment, customers usually care about safety, reliability, operating cost, and long-term performance. Based on our manufacturing experience, we focus on several important technical areas.
The internal layout of our GCK switchgear is designed to provide clear separation between power circuits and control circuits. A well-organized structure makes installation easier and helps engineers identify components quickly during inspection.
Copper busbars are widely used in our switchgear systems because copper provides good electrical conductivity and stable performance. Proper surface treatment and insulation protection help improve corrosion resistance and electrical reliability.
The cabinet frame is manufactured with precision processing technology to ensure accurate assembly. A strong structure helps the equipment maintain stable performance during long-term operation.
