GGD AC Low Voltage Distribution Cabinet

The GGD AC low-voltage distribution cabinet is a safe, economical, and professional solution for power distribution in electrical systems with a rated frequency of 50Hz and operating voltages up to 380V. It is widely used in power plants, substations, and industrial enterprises to serve as a high-reliability power, lighting, and distribution unit. This product is designed in full compliance with IEC60439-1 and GB7251.1 standards.

Product Overview

The GDF cabinet structure is built with a focus on internal compartmentalization. Unlike traditional fixed cabinets, the GDF uses fixed partitions to separate the busbar, functional units, and cable zones. This design prevents fault propagation and enhances operator safety during maintenance. It combines the structural stability of the GGD series with the safety-first approach of the GCS/GCK series, making it an ideal choice for modern industrial power distribution.

Product Features

  • Advanced Structural Frame: The 8MF steel frame is designed with modular mounting holes (E=20mm), allowing for versatile internal component layouts and high structural precision.
  • Superior Thermal Design: The cabinet features integrated cooling vents at both the top and bottom. Heat generated by components creates a natural chimney effect, ensuring efficient heat dissipation.
  • High-Quality Enclosure: The cabinet door is connected to the frame via galvanized swivel hinges, providing easy access and preventing paint peeling. The entire enclosure is treated with electrostatic powder coating for maximum durability.
  • Safety & Grounding: Features a comprehensive grounding system where the door and the frame are connected through multiple strands of flexible copper wire, ensuring a reliable protective circuit.
  • Standardized Protection: Offers a standard protection rating of IP30, which can be customized between IP20 and IP40 based on specific environmental requirements.

Technical & Artistic Details

The GGD system combines robust engineering with a clean, industrial aesthetic for long-term reliability.

  • Breaking Capacity: Designed to handle rated short-time withstand currents up to 50kA, ensuring system stability during faults.
  • Compact Footprint: Available in various widths (600mm to 1200mm) to accommodate different circuit densities while optimizing space in the distribution room.
  • Ease of Installation: Supports both top and bottom cable entry, with a spacious internal layout for easy field wiring and routine maintenance.
