GGD Type
// Product Advantages
By adopting composite insulation methods, optimizing electrode shapes, and improving electric field distribution, the entire cabinet structure is compact, effectively reducing the occupied area.
When designing, full consideration is given to the heat dissipation problem during the operation of the cabinet. There are different numbers of heat dissipation holes at the upper and lower ends of the cabinet. When the cabinet components heat up. the heat rises and is discharged through the upper slot holes, while cold air continuously replenishes through the lower slot holes, forming a natural ventilation duct from bottom to top of the sealed cabinet, achieving the purpose of heat dissipation.
The cabinet surface paint has good adhesion and texture. The entire cabinet is in a matte color scheme, avoiding dazzling effects and creating a comfortable visual environment for the on duty personnel.
The top cover of the cabinet can be removed as needed to facilitate the installation and adjustment of the main busbar on site.
Using the golden ratio method to design the segmentation dimensions of each part, making the entire cabinet aesthetically pleasing and refreshing.
The protection level of the cabinet is Ip30, and it can also be selected between IP20 to IP40 according to user needs.

// The following are the common application scenarios of the GGD Type Low-voltage Switchgear:
I. Industrial Production Field
1. Factory Power Distribution System
As the core low-voltage power distribution equipment in industrial plants, it is used for centralized control and protection of power distribution (such as motor control and power supply for production line equipment), lighting distribution, and auxiliary equipment (ventilation and refrigeration systems). It is suitable for various industrial scenarios such as machinery manufacturing, chemical industry, metallurgy, textile, and food processing. It supports stable power distribution and meets the needs of multiple loads operating simultaneously.
2. Workshop and Power Control
It integrates motor control units and directly drives power equipment such as water pumps, fans, and compressors. Together with protection devices (such as circuit breakers and fuses), it realizes fault protection against overload, short circuit, etc.
II. Commercial and Public Building Field
1. Commercial Complexes and Office Buildings
It provides power distribution support for the lighting systems, air conditioning units, elevators, and fire protection equipment (such as sprinkler pumps and smoke exhaust fans) in shopping malls and office buildings, ensuring the stable power supply of large buildings. Smart monitoring modules can be configured to achieve digital management of the power distribution system and energy consumption monitoring.
2. Hotels and Public Facilities
It meets the power distribution needs of areas such as hotel guest rooms, banquet halls, and kitchens. At the same time, it supports the safe power supply of public facilities (such as medical equipment in hospitals and teaching power consumption in schools), and adapts to complex scenarios with multiple circuits and multiple loads.
III. Residential and Community Power Distribution
1. Community Power Distribution Rooms and Apartment Buildings
As the low-voltage main power distribution device in residential communities, it converts the high-voltage power grid into 220/380V low-voltage electricity and distributes it to each residential building, shops, and public areas (such as street lamps, landscape lighting, and charging piles). It has a modular design and can flexibly expand the number of circuits to adapt to the growth of residential electricity loads.
2. Villas and Multi-story Buildings
In small and medium-sized buildings, it serves as the main power distribution box for households or the floor distribution box, realizing household metering, leakage protection, and circuit sub-control to ensure the safety of household electricity use.
IV. Power System and Infrastructure
1. Substations and Power Distribution Stations
As the low-voltage side power distribution equipment of substations, it receives the low-voltage electrical energy output by transformers and distributes the power to surrounding users or lower-level power distribution networks, supporting the ring network power supply or radial power supply mode.
2. Transportation Hubs and Municipal Engineering
It is applied to the power distribution systems of airports, subways, and railway stations, supplying power to lighting, security inspection equipment, escalators, signal systems, etc., and meeting the requirements of high reliability and protection levels (such as IP30/IP40). In sewage treatment plants, water supply pumping stations, and urban lighting projects, it adapts to environments such as humidity and dust to ensure the continuous operation of municipal facilities.
V. New Energy and Special Scenarios
1. Power Distribution of New Energy Power Generation
On the low-voltage side of photovoltaic power plants and wind power generation projects, it is used to collect the electrical energy of power generation units and connect to the power grid, supporting the distribution and protection of the electrical energy output by inverters.
2. Temporary Power Usage and Construction Sites
As a temporary power distribution device for construction sites, temporary exhibition halls, and outdoor operations, it has the characteristics of convenient installation and strong protection, meeting the safety and flexibility requirements of temporary power usage.
3. Special Environment Scenarios
Through customized design (such as moisture-proof, dust-proof, and anti-corrosion treatment), it is suitable for humid and rainy areas, dusty environments (such as mines and granaries), or industrial sites with mildly corrosive gases.
VI. Emergency and Backup Power Supply Systems
It is equipped with backup power supply equipment such as generators and UPS to form an emergency power distribution system. It can quickly switch to the backup power supply during a power outage to ensure the continuous power supply of key loads (such as data centers, hospital operating rooms, and fire protection systems).
// FAQ
Q: Does the GGD equipment support on-site installation and expansion?
A: Yes, it does. The cabinet body adopts a modular structure. On-site, a single-row or multi-row arrangement can be selected according to the spatial conditions. In the later stage, the circuit capacity can be expanded by adding drawer units or expansion cabinets. It should be noted that enough maintenance space needs to be reserved.
Q: How does the protection level of the equipment correspond to different environments?
A: The conventional IP30 is suitable for dry and clean indoor environments. IP40 adds a dust-proof design and is suitable for dusty scenarios (such as factories and construction sites). IP54 has the ability to prevent dust and water and can be used outdoors or in humid environments (a rain canopy needs to be equipped). For customized protection, the environmental parameters need to be explained in advance.
Q: Does the equipment provide customized design?
A: Yes, it does. The cabinet body material, surface treatment, internal layout, and even explosion-proof modification can be customized according to special requirements. Detailed technical drawings or working condition descriptions need to be provided.
