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.


Product Details

GGD Modular Low-Voltage Switchgear Cabinet

The GGD-Type AC Low-Voltage Switchgear Cabinet is a fixed low-voltage distribution device designed with the principles of safety, economy, rationality, and reliability. It complies with GB/T 7251.12-2013 and IEC 60439-1 standards and is widely used in indoor low-voltage distribution systems of power plants, substations, industrial and mining enterprises, and commercial buildings. It performs the core functions of power conversion, distribution, and control for motors, lighting, and other distribution equipment.

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.
