Selling Points and Advantages
The design breaks with the conventional structural configuration of previous products, adopting a modular, prefabricated assembly structure with screw-fastened connections. The frame, doors, and panels are all phosphated and then coated with polyester powder in an orange-peel finish; non-coated components are galvanized and passivated. The enclosure has an IP30 protection rating. The GGD switchgear typically features top-and-bottom cable entry, but can also be configured for side-entry, offering flexible electrical scheme design and a well-optimized structural layout.
