LV Power Distribution Cabinet

Industrial Enterprises:
Power distribution and motor control (MCC) in industries such as metallurgy, mining, petrochemical, textiles, and machinery manufacturing.

Infrastructure:
Power and lighting distribution in high-rise buildings, shopping malls, stations, ports, and hospitals.

Power Systems:
Low-voltage side of substations, distribution stations, reactive power compensation, and conventional distribution projects.

Special Scenarios:
Wall-mounted/embedded installations (for small loads) and floor-standing installations (for large loads), suitable for indoor dry environments.

Design and Standards
Conforms to national standards GB 7251.1 and IEC 60439-1, passing type testing for safety and reliability.
Designed for indoor wall-mounted installation with a front-opening door, focusing operations and maintenance at the front of the cabinet.

Cabinet Structure
Material: High-quality cold-rolled steel (frame may use C-type profiles), treated with pickling and phosphating, then electrostatically sprayed for corrosion resistance and durability.
Frame: Angle steel welded or C-type profiles assembled, providing a strong and high-strength structure.
Dimensions: Standard floor-mounted size (W × D × H): 600~1000mm × 400~600mm × 1600~2200mm; wall-mounted models are smaller (e.g., 500×300×800mm).
Compartment Design: Independent busbar room (top copper busbar), electrical room (layered component installation), and cable room (bottom entry), with a clear layout.

Electrical Configuration
Main Circuit: Optional frame circuit breakers (e.g., DW15/DW45) or molded case circuit breakers, rated current ≤ 630A.
Control Circuit: Integrated contactors, thermal relays, and fuses, suitable for motor start/stop and protection.
Wiring: Supports top/bottom entry wiring with ample internal space for large-section cables (≤240mm²).
Protection Rating: Standard IP30; some models can reach IP40; sealed models (IP54) can be customized for special environments.

Outstanding Cost-Effectiveness
Simple Structure: No drawer mechanism, low failure rate, and lowest cost, making it ideal for cost-sensitive projects.
Wide Adaptability: Flexible circuit configurations can be assembled into various cabinet types, such as incoming, feeder, motor control, and lighting.
Easy Installation: Wall-mounted design saves space, fast on-site wiring, and commissioning for quick operation.

Convenient Maintenance
Front-Maintenance Design: When the cabinet door is opened, all internal components are fully exposed, making fault diagnosis and replacement efficient and straightforward.
No Fragile Parts: Fixed structure without drawer units, avoiding mechanical failures and ensuring stable long-term operation.
Integrated Control Panel: Includes instruments, buttons, and indicator lights, providing convenient local operation and monitoring.

Safety and Reliability
Separate Busbar and Cable Compartments: Excellent short-circuit fault isolation, enhancing system safety.
Grounding: A dedicated grounding bar for metal components ensures reliable grounding and perfect electric shock protection.
Mechanical Interlock: The circuit breaker is mechanically interlocked with the cabinet door, preventing the door from opening during closing, ensuring maintenance safety.
