4. The inclination angle between the equipment installation and the vertical plane shall not exceed 5 °;
5. The equipment should be installed in places without severe vibration and impact, as well as in places where electrical components are not susceptible to corrosion;
6. When users have special requirements, they can negotiate with the manufacturer to resolve them.
III. Structural characteristics
The cabinet body of GGD type AC low-voltage distribution cabinet adopts the form of a universal cabinet, and the frame is assembled by local welding of 8MF cold-formed steel. The frame parts and special supporting parts are supplied by designated steel production factories to ensure the accuracy and quality of the cabinet body. The components of the universal cabinet are designed according to the modular principle and have 20 installation holes. The high universal coefficient enables factories to achieve pre production, shortening the production cycle and improving work efficiency.
The design of GGD cabinets fully considers the heat dissipation issues during cabinet operation. There are different numbers of heat dissipation slots on both ends of the cabinet. When the electrical components inside the cabinet heat up, the hot air rises and is discharged through the upper slot, while the cold air is continuously replenished into the cabinet through the lower slot, forming a natural ventilation channel from bottom to top in the sealed cabinet, achieving the purpose of heat dissipation.
According to the requirements of modern industrial product design, the GGD cabinet adopts the golden ratio method to design the cabinet body shape and the division dimensions of each part, making the whole cabinet beautiful and elegant, with a new look. The cabinet door is connected to the frame with a pivot type movable hinge, which is easy to install and disassemble. The folded edge of the door is embedded with a mountain shaped rubber strip. When closing the door, the strip between the door and the frame has a certain compression stroke, which can prevent direct collision between the door and the cabinet, and also improve the protection level of the door.
The instrument door equipped with electrical components is connected to the frame with multiple strands of soft copper wire, and the installation parts inside the cabinet are connected to the frame with rolling screws, forming a complete grounding protection system for the entire cabinet.
The cabinet is coated with polyester orange baked paint, which has strong adhesion and good texture. The entire cabinet has a matte color tone, avoiding glare effects and creating a comfortable visual environment for the on duty personnel.
The top cover of the cabinet can be removed when needed to facilitate the assembly and adjustment of the main busbar on site. The four corners of the cabinet top are equipped with lifting rings for lifting and shipping.
The protection level of the cabinet is IP30, and users can also choose between IP20-IP40 according to the requirements of the usage environment.

Our High Quality GGD Series Low Voltage Switchgear 2500A 380V is developed for customers who need safe and efficient low-voltage power distribution solutions. It is widely used in factories, commercial buildings, renewable energy projects, industrial parks, and public infrastructure.
The GGD series low voltage switchgear combines a strong cabinet structure, reliable electrical components, and practical design concepts. It helps users control, distribute, and protect electrical power systems while making operation and maintenance easier.
As a manufacturer specializing in medium and low voltage power equipment up to 35kV, we provide not only standard products but also customized solutions according to different project requirements.
High Quality GGD Series Low Voltage Switchgear 2500A 380V is a low-voltage electrical distribution cabinet designed for receiving, controlling, and distributing electrical energy in power systems.
The "GGD" series represents a fixed-type low-voltage switchgear structure commonly used in industrial power distribution applications. The equipment is designed for AC low-voltage systems and provides reliable protection and control for electrical circuits.
The rated current of 2500A means that this switchgear can handle electrical systems requiring high current distribution capacity. The 380V voltage level makes it suitable for many industrial and commercial power systems.
In daily applications, our customers use GGD low voltage switchgear for:
Power distribution in manufacturing factories
Electrical control systems in industrial plants
Energy management projects
Commercial building power supply
Infrastructure electrical systems
Compared with simple distribution cabinets, professional low voltage switchgear provides better protection, clearer electrical management, and stronger adaptability for complex working conditions.
The working principle of GGD low voltage switchgear is simple: it receives electrical power from the main power source and safely distributes electricity to different loads.
When electricity enters the switchgear, the incoming unit first receives power through the main circuit. The internal busbar system then transfers electrical energy to different outgoing circuits.
Each outgoing circuit can supply power to different equipment, such as motors, production machines, lighting systems, or other electrical devices.
Inside the cabinet, protection components monitor the electrical conditions. If abnormal situations occur, such as overload or short circuit, protective devices can disconnect the circuit to help prevent equipment damage.
This working method allows users to manage electricity safely while improving system reliability.
During our manufacturing process, we pay close attention to every structural detail because a switchgear cabinet must remain stable under long-term operation.
The cabinet frame is the basic structure of the equipment. It provides mechanical support and protects internal electrical components from external impact.
The busbar system is responsible for electrical energy transmission inside the cabinet. High-quality conductive materials and proper installation methods help improve electrical performance.
The cabinet can include circuit breakers, contactors, meters, protection devices, and control components according to customer requirements.
The protection system helps monitor electrical conditions and improves operation safety during daily use.
