GGD Modular Low-Voltage Switchgear Cabinet
The GGD adopts an 8MF cold-formed steel modular frame, with “standardized interfaces + customized layouts” as its core design principle. It adapts to different spaces, loads, and industry requirements, offering easy installation and maintenance, as well as low expansion costs.
GGD Modular Low-Voltage Switchgear Cabinet
Advantages & Features
Modular Combination Design: Functional units (incoming, outgoing, capacitor compensation, motor control) can be independently removed and replaced. Supports front and rear doors, wall-mounted or free-standing installation, and flexible cable entry from top, bottom, or side.
Wide Capacity Coverage: Rated current ranges from 200A to 3150A, with modular stacking allowing capacity expansion to meet dynamic power distribution needs from small workshops to large factories.
Cross-Brand Component Compatibility: Cabinets feature pre-installed E = 20 mm / 100 mm modular mounting holes, compatible with mainstream domestic and imported circuit breakers and contactors. Component upgrades or replacements can be made without altering the cabinet structure.
Customized Structural Optimization: Cabinet dimensions can be tailored to the site, including wall-mounted, floor-standing, or embedded types. In an automotive plant case, three standard cabinets were integrated into two customized cabinets, saving 30% of floor space.
Tool-Free, Rapid Assembly and Commissioning: On-site modification cycle reduced by 50%.
Offline Maintenance for Faulty Modules: Reduces system downtime.
Supports Extended Functions: Can integrate with PLCs, UPS dual power switching, and other expanded functionalities.
