GGD Low-Voltage Switchgear (also known as the GGD fixed-mounted switch cabinet) is a standardized AC low-voltage power distribution cabinet. It is primarily used for energy conversion, distribution, and control in power systems operating at 50/60 Hz with a rated voltage of 380V (up to 660V) and rated currents up to 3150A (with some variants up to 5000A

Key Features & Construction
Fixed-Mounted Design: Unlike withdrawable (drawer-type) units like GCK or MNS, components in GGD are fixed in place, making it a cost-effective choice for stable, long-term installations.
Modular Frame: Constructed from 8MF cold-formed steel with a modular 20mm mounting hole pattern, allowing for flexible component layout and high structural precision.
Effective Heat Dissipation: The cabinet features ventilation slots at the top and bottom, creating a natural chimney effect to cool internal components during operation.
Ease of Maintenance: Includes a removable top cover for easy main busbar adjustment on-site and doors connected by pivot hinges for simple removal.
Safety: Features a complete grounding protection circuit where all internal components and doors are bonded to the frame.
Common Applications
GGD switchgear is a "workhorse" in various sectors:
Power Plants & Substations: Serving as the primary low-voltage distribution point.
Industrial & Mining: Controlling heavy machinery, production lines, and motors.
Commercial Buildings: Powering HVAC systems, lighting, elevators, and shopping malls.
Infrastructure: Used in airports, rail transit, and public utility projects.
