Distribution Box ggd Power Distribution Level
GGD low-voltage distribution cabinets are designed for AC systems up to 380–660V with rated currents up to 3150A, suitable for industrial and commercial power distribution.
Overview
GGD cabinets are fixed-type low-voltage switchgear assemblies used for power distribution, control, and protection in industrial, commercial, and utility environments. They operate on AC 50/60 Hz systems and are designed to safely manage electricity from the main supply to multiple sub-circuits, ensuring reliable energy flow and system protection .
Power Distribution Level
- Rated Voltage: Typically 380V–415V, with some models supporting up to 660V .
- Rated Current: Up to 3150A, suitable for distribution transformers of 2000 kVA and below .
- Short-Circuit Capacity: High breaking capacity to handle overloads and short circuits, ensuring system stability .
Structural and Functional Features
- Fixed-frame design: Constructed from heavy-duty steel for rigidity, thermal dissipation, and short-circuit resistance .
- Internal Components: Includes main circuit breakers (MCCBs/ACBs), fuse switch disconnectors, isolator switches, and a copper busbar matrix for efficient power distribution .
- Protection Systems: Provides overload, short-circuit, leakage, and lightning surge protection to prevent equipment damage and downtime .
- Modular Assembly: Flexible configurations allow adaptation to different industrial layouts and single-line diagrams .
Applications
GGD cabinets are widely used in:
- Power plants and substations for energy conversion and distribution .
- Industrial enterprises and factories to supply machinery, production lines, and auxiliary facilities .
- Commercial buildings for lighting and general power distribution .
Standards Compliance
GGD cabinets comply with international and national standards, including IEC 439, GB 7251, and JB/T9661, ensuring safety, reliability, and compatibility with modern electrical systems .
Summary
GGD low-voltage distribution boxes provide a robust, high-capacity solution for industrial and commercial power distribution, combining high current handling, structural strength, and advanced protection features. They are ideal for environments requiring safe, reliable, and flexible electrical distribution.
