Scope of Application

The GGD Type AC Low-Voltage Switchgear is suitable for power distribution systems in power plants, substations, factories, mines, and other industrial facilities. It operates on 50Hz AC power with a rated working voltage of 380V and a rated working current up to 3150A. It serves as equipment for power conversion, distribution, and control for power, lighting, and distribution systems.

The GGD AC low-voltage switchgear cabinet is designed in accordance with principles of safety, economy, rationality, and reliability. It features high breaking capacity, excellent dynamic and thermal stability, and flexible electrical configurations.

Operating Environment Conditions

• Ambient air temperature: -50°C to +40°C (24h average ≤ +35°C).
• Installation altitude: Not exceeding 2000 meters.
• Relative humidity: ≤ 50% at +40°C (higher humidity allowed at lower temperatures).
• Inclination angle: Not exceeding 5° from vertical.
• Environment: Free from severe vibration, shock, or corrosive elements.

1. Universal Design: Frame assembled via partial welding of 8MF cold-formed steel sections with 20-module mounting holes for high compatibility.

2. Heat Dissipation: Multiple ventilation slots at top and bottom create a natural cooling pathway for effective thermal management.

3. Aesthetics & Protection: Golden ratio design for a modern appearance. Doors use pivot-type hinges and V-shaped rubber-plastic strips for IP30 protection.

4. Finishing: Polyester orange-baked paint offers strong adhesion, matte texture, and reduced glare.

SC(B) 9-30~2500 epoxy resin cast dry-type transformers are suitable for critical environments such as high-rise buildings, commercial centers, airports, tunnels, chemical plants, and nuclear power stations. They serve as reliable, fire-resistant upgrades for traditional oil-immersed transformers.

• Core: Premium cold-rolled grain-oriented silicon steel sheets.
• Windings: High-quality copper foil for low-voltage; epoxy vacuum resin cast for high-voltage.
• Safety: Fire-resistant, pollution-free, and maintenance-free.
• Intelligence: Equipped with intelligent signal temperature control systems for automatic monitoring and fan control.
• Design: Compact size, lightweight, and low installation costs.
