GDF fixed partition low-voltage switchgear

The GDF series is a fixed partition low-voltage switchgear designed for power distribution and motor control in systems with a rated frequency of 50Hz and operating voltages up to 660V. It is specifically engineered to bridge the gap between fixed cabinets and withdrawable units, offering high reliability and safety in a cost-effective fixed-partition design. The system is widely used in power plants, substations, and industrial enterprises, fully complying 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

  • Enhanced Safety Partitioning: Features a clear separation between the busbar room, functional unit room, and cable room to ensure maximum isolation.
  • Robust Fixed Design: Utilizes high-quality profiles to ensure the cabinet has excellent mechanical strength and short-circuit withstand capabilities.
  • Flexible Functional Units: Each functional unit is independent, allowing for safer inspection and maintenance of individual circuits without affecting the entire system.
  • Efficient Cable Management: A dedicated cable compartment is provided at the side or rear, facilitating easy installation and organized wiring for both power and control cables.
  • Anti-Corrosion Durability: All metal parts undergo rigorous surface treatment, including galvanization and electrostatic powder coating, for long-term reliability.

Technical & Artistic Details

The GDF system is engineered to provide a professional and clean appearance while maintaining heavy-duty performance.

  • Thermal Stability: Designed with optimized air vents to ensure natural convection and efficient heat dissipation under full load.
  • High Breaking Capacity: The main busbar is designed to handle rated currents up to 4000A, ensuring stability in large-scale power applications.
  • Maintenance Accessibility: Front and rear access options allow for easy routine inspections and quick troubleshooting.
