GGD GGJ
Fixed low-voltage switchgear
The GGD/GGJ series AC switchgear is designed for use in three-phase four-wire or three-phase five-wire power systems with a frequency of 50 Hz and a rated operating voltage of 400 V, for power distribution, motor control, and capacitor compensation.
Features
● Rated voltage: 400V
● Rated current: 400~2500A
● Rated frequency: 50 Hz
● Rated insulation voltage: 690V
● Insulation voltage of auxiliary circuit: 400V
● Rated impulse withstand current (grounding circuit): 6kV
Strength
● The cabinet has multiple ventilation slots at both the upper and lower ends, creating a natural airflow path from bottom to top within the sealed cabinet to address heat dissipation issues.
● The instrument door with electrical components and internal installation parts form a complete grounding protection circuit, ensuring continuity of grounding.
● The main busbars are arranged at the upper rear of the cabinet, using AMJ-type busbar clamps made from high-strength unsaturated polyester DMC/SMC materials, which provide high mechanical and insulation strength.The top cover of the cabinet is removable, facilitating on-site assembly and adjustment of the main busbars.
● The cabinet is coated with electrostatic powder paint, offering strong adhesion, while internal components are galvanized and passivated to enhance “three-proof” performance (moisture-proof, dust-proof, and anti-corrosion).
● The cabinet supports various cable entry options, including top, bottom, and rear entry, to meet different projectrequirements.
