380V Low Voltage Main Electrical Distribution Cabinet Galvanized Steel 63A 100A

Our Low Voltage Main Electrical Distribution Cabinets (MDB) are the backbone of industrial and commercial power systems. Engineered for the safe and efficient distribution of electricity, these 380V cabinets receive power from a transformer and distribute it to various sub-circuits across the facility.

Manufactured from high-strength Galvanized Steel, these cabinets are designed to house circuit breakers, busbars, and monitoring equipment while protecting them from dust, moisture, and mechanical impact. Each unit is custom-configurable to meet specific project load requirements, ensuring a turnkey solution for factories, data centers, and high-rise infrastructures.

• Heavy-Duty Galvanized Construction: The frame and panels are made from high-quality galvanized steel, offering superior corrosion resistance and structural rigidity compared to standard cold-rolled steel.

• Modular Interior Design: Features adjustable mounting rails and universal busbar supports, allowing for the easy integration of various brands of MCBs, MCCBs, and AC contactors.

• Superior Thermal Management: Equipped with natural ventilation louvers or optional forced-air cooling fans to ensure that high-current components operate within their thermal limits, preventing nuisance tripping.

• IP-Rated Environmental Sealing: Available in IP54 or IP65 configurations, featuring high-quality polyurethane foam gaskets to protect sensitive electronics in damp, dusty, or outdoor environments.

• Enhanced Operator Safety: Includes internal dead-front covers, mechanical interlocks, and ground-fault protection to minimize the risk of accidental contact with live components during maintenance.

1. Industrial Manufacturing: Centralized power management for production lines, heavy machinery, and workshop lighting.

2. Commercial Real Estate: Main distribution boards for shopping malls, office complexes, and hotels.

3. Infrastructure Projects: Reliable power hubs for subway stations, airports, and water treatment facilities.

4. Renewable Energy: Main AC combiner cabinets for large-scale solar farms and wind power installations.

• Turnkey Customization: We provide full CAD design support, allowing you to specify exact component layouts, entry/exit cable locations, and integrated digital metering.

• Maintenance-Friendly Layout: Spacious interior allows for easy cable termination and generous bending radii, significantly reducing installation time for field electricians.

• High-Strength Busbar Systems: Tinned copper busbars are used to ensure maximum conductivity and resistance to short-circuit electromagnetic forces.

• Factory Tested: Every cabinet undergoes rigorous insulation resistance, grounding continuity, and functional power tests before dispatch.

Q: Can the cabinet be customized for outdoor use?

A: Yes. For outdoor installations, we provide a "weatherproof" package which includes an IP65 rating, a sloped rain hood, and a specialized outdoor-grade UV-resistant powder coating.

Q: Does the cabinet come with components installed?

A: We offer both options. We can supply the "empty" galvanized enclosure with mounting plates, or a "fully wired" cabinet integrated with specified brands like CHINT, Schneider, or ABB.

Q: What is the typical lead time for a custom distribution cabinet?

A: Standard enclosures are usually ready in 7-10 days. Fully integrated and wired custom cabinets typically take 3-4 weeks depending on the complexity and component availability.

XL-21 Low-voltage power distribution cabinet is suitable for power distribution of three-phase four-wire or three-phase five-wire system with AC voltage of 500 volts and below in power plants and industrial and mining enterprises. XL-21 low-voltage power distribution cabinet is installed against the wall of the indoor device, and inspected in front of the screen. The shell IS made of steel plate bending, and the knife switch handle is on the upper part of the right column in front of the box, which can be used for switching power supply. According to the needs of users, different types of circuit breakers with different current levels can be selected to meet the needs of different users.
