The GGD low-voltage AC switchgear is constructed from cold-rolled steel plates using an epoxy powder electrostatic spraying process. The cabinet frame is assembled from structural steel sections connected by bolts. Featuring a fully enclosed structure, all internal electrical components are permanently mounted.
GGD model AC applies to power plant, substation industrial enterprise, as motive force in AC 50/60Hz, rat ed working voltage 380/400V, rated current 3150A and below distribution system. For transferring power energy, distributing and controlling of lightning and distribution. High breaking capacity, rated short time current will reach 50kA. Flexible circuit scheme, convenient combination, novel structure.
Product feature
● Stability: High breaking capacity, good dynamic thermal stability, and stable power output under various working conditions, ensuring continuous and stable operation of the power system.
● Flexibility: Flexible electrical solutions, convenient combinations, can be connected in series, and can be configured according to different power requirements to meet the needs of various application scenarios.
● Economy: GGD cabinet power distribution solutions are flexible, ensuring safety while providing cost-effective power solutions.
● Design Advantages: Components of the general-purpose cabinet are designed based on a modular principle, with 20mm module installation holes and a high degree of universality. This enables factories to carry out pre-production, shorten production cycles, and improve work efficiency.
● Quality Advantages: The GGD cabinet structure adopts a general-purpose cabinet design, with the frame partially welded from cold-formed steel profiles, making the structure sturdy.
