1. Product Features

GGD low voltage switchgear adopts a robust fixed modular frame structure with high mechanical strength and strong overall stability. The cabinet body features anti-corrosion electrostatic spraying, ensuring rust resistance and durability for long-term indoor operation. Reasonable independent compartment layout effectively isolates busbar, instrument, cable and operating areas, greatly improving operation and maintenance safety. Natural ventilation heat dissipation structure reduces internal temperature rise and ensures stable continuous load operation.

Equipped with high-quality copper busbars, the switchgear achieves low power loss, excellent electrical conductivity and strong overload capacity. It supports various circuit schemes including incoming power, outgoing feeder, metering, lighting distribution and reactive power compensation. Multiple cabinets can be combined side by side to expand the power distribution system flexibly. Compared with withdrawable switchgear, GGD fixed-type design has fewer movable parts, lower failure rate and more cost-effective performance, making it highly suitable for stable and long-term industrial power distribution projects.
