8MF Steel Frame Commercial Low Voltage Distribution Cabinet GGD IEC LV Switchgear

The GGD Low Voltage Fixed-Type Switchgear is a globally recognized solution for power distribution, lighting, and motor control in AC 50Hz/60Hz systems. Optimized for operating voltages of 380V, 400V, and 415V, the GGD series is the industry standard for facilities that prioritize structural durability and ease of maintenance.

Constructed from a combination of high-strength cold-rolled steel and aluminum-zinc plates, these cabinets are engineered to house Air Circuit Breakers (ACB) and Moulded Case Circuit Breakers (MCCB) in a fixed-panel arrangement. Unlike more complex withdrawable units, the GGD design provides a spacious internal layout and superior thermal stability, making it the most cost-effective and reliable choice for substations, industrial plants, and commercial infrastructure.

• High Breaking Capacity: Engineered to withstand significant electrical stress with a short-circuit breaking capacity (Icu) of up to 50kA, ensuring system safety during fault events.

• Rugged 8MF Frame Construction: The cabinet frame is built using 8MF cold-formed steel sections, providing exceptional rigidity and precision for mounting heavy busbars and breakers.

• Superior Busbar Engineering: Features high-conductivity T2 Copper or Aluminum busbars with silver-plated contact points to minimize resistance and heat generation.

• Enhanced Natural Ventilation: Strategically placed cooling louvers on the top and bottom of the cabinet door facilitate natural air convection, maintaining optimal internal temperatures without high-energy cooling systems.

• B2B Customization: Fully compatible with international component brands (Schneider, ABB, Siemens) or high-performance domestic series, allowing for tailored single-line diagram (SLD) integration.

1. Industrial Manufacturing: Main power feed for factories, textile mills, and chemical processing plants.

2. Power Substations: Reliable low-voltage side control for 10kV/0.4kV step-down transformers.

3. Mining & Extraction: Heavy-duty power hubs for remote mining sites requiring mechanical durability.

4. Commercial Real Estate: Centralized power distribution for hospitals, hotels, and large office complexes.

• Maintenance Accessibility: The fixed-panel design allows technicians to access all components easily from the front and rear, simplifying routine inspections and cleaning.

• Lower Total Cost of Ownership: By eliminating the complex mechanical parts of withdrawable units, GGD switchgear offers a lower initial investment and reduced long-term maintenance costs.

• Corrosion Resistance: Our cabinets undergo a multi-stage pickling and phosphating process followed by a UV-resistant epoxy powder coating (RAL 7035/7032), ensuring a 20-year service life.

• Safety First: Includes a dedicated grounding busbar system and mechanical interlocks to prevent unauthorized entry and ensure operator safety during manual switching.

Q: Can this cabinet be used as a Motor Control Center (MCC)?

A: Yes. We can customize the GGD cabinet to include soft starters, VFDs, or Star-Delta starters for centralized motor management.

Q: What is the benefit of the Al-Zn coating over traditional painted steel?

A: Aluminum-Zinc coating provides superior self-healing properties against scratches and significantly better resistance to high-humidity environments.

Q: Do you offer pre-assembled units?

A: We offer both "empty enclosures" for local panel builders and "fully populated, wired, and tested" switchgear cabinets ready for on-site commissioning.

GCS low voltage withdrawable switchgear assembly (hereinafter referred to as device) is the former state Ministry of Machinery, the Ministry of Electric power joint design group according to the industry authorities, the majority of power users and design units developed in line with the national conditions, with high technical performance indicators, can adapt to the development of the power market needs and can compete with the existing introduced products. In July 1996, the device passed the appraisal jointly presided over by two departments in Shanghai, and received the attention and affirmation of the production and manufacturing units and power use departments.

The device is suitable for power plant, petroleum, chemical, metallurgy, textile, high-rise building and other industries of power distribution system. In large power plants, petrochemical systems and other places with a high degree of automation, requiring computer interface, as a three-phase AC 50(60)Hz, rated working voltage 380V, rated current 4000A and below the distribution, centralized control of the motor, reactive power compensation of the low-voltage distribution device.

The device conforms to IEC439-1 and GB7251.1 standards.

1. The ambient air temperature is not higher than +40℃, not lower than -5℃, and the average temperature within 24 hours is not higher than +35℃.

2. The relative humidity at high temperature is not more than 50%, in the lower temperature is allowed to have a high relative humidity, such as +20℃ at 90%, but should take into account the temperature change, may occasionally produce moderate condensation.

3. The altitude does not exceed 2000 meters.

4. Installation tilt shall not exceed 5°.

5. No dust, corrosive gas and rain immersion indoors.

The body of GGD AC LV fixed type switchgear adopts universal cabinet type. Framework is assembled with BMF cold bending bar steel through part welding. Framework components and special mating elements are matched by bar steel pointed manufactory for ensuring the precision and quality of cabinet. Components of universal cabinet is designed according to module principle, and with 20 modulus mounting hole and high universal coefficient; Completely in view of the heat rejection during cabinet running. Heat rejection slots of different quantities are installed in upper and underside both ends of cabinet; According to the requirements on mold design for modern industry products, adopting the method of golden mean ratio to design cabinet outline and parting dimensions of each part, to make the whole cabinet beautiful and decent: Cabinet gate is connected with framework with rotation axis type movable hinge, With convenient installation and disassembly.
