The GGD Fixed Type Low Voltage Switchgear is an industry-standard solution for power distribution, lighting, and motor control in AC 50Hz/60Hz systems. Rated for operating voltages up to 380V/400V/415V, the GGD cabinet is renowned for its high breaking capacity, excellent thermal stability, and flexible circuit arrangements.
Constructed with a reinforced frame using cold-rolled steel or aluminum-zinc coated plates, this switchgear provides a rugged and durable housing for main incoming feeders and branch circuits. As a fixed-panel assembly, the GGD series offers a more cost-effective and easier-to-maintain alternative to withdrawable units, making it the primary choice for power substations, industrial mining enterprises, and high-rise infrastructures.
High Breaking Capacity: Engineered to handle high short-circuit currents (up to 50kA), ensuring the safety of the entire electrical network during fault conditions.
Modular Fixed-Panel Design: The "Fixed-Type" architecture simplifies maintenance and provides a clear, organized layout for circuit breakers, busbars, and measuring instruments.
Superior Material Integrity: The cabinet frame is assembled using 8MF cold-formed steel. This provides high precision and structural rigidity, allowing the cabinet to support heavy internal components without deformation.
Optimized Thermal Management: Features integrated ventilation louvers on the top and bottom of the cabinet door, creating a natural convection cooling path to prevent heat buildup during high-load operation.
Universal Component Compatibility: Designed to house a wide variety of international and domestic brands of MCCBs, ACBs, and fuse switches, allowing for total project customization.
