Product Description
Heavy Duty Waterproof Distribution Box | Dustproof & Corrosion Resistant Power Cabinet
Product Overview

The Heavy Duty Series Power Cabinet is engineered for high-exposure industrial environments where electrical integrity is non-negotiable. This enclosure provides a centralized, high-strength housing solution for power distribution, motor control, and automation components. Designed to withstand mechanical stress, chemical exposure, and extreme weather, it serves as a critical protective barrier for large-scale industrial and utility electrical systems.

Core Technical Features
Advanced Corrosion Resistance

The cabinet undergoes a multi-stage pre-treatment process followed by a high-micron Epoxy Polyester powder coating. This ensures the unit remains rust-free in high-salinity coastal areas or chemical processing plants. For extreme acidity, Grade 316 Stainless Steel options are available to meet ASTM standards.

Heavy-Duty Structural Integrity (IK10)

Unlike standard residential boxes, this power cabinet is constructed with a reinforced frame and thickened panels (up to 2.0mm steel thickness). It is rated IK10 for impact, meaning it can withstand external mechanical shocks common in mining, oil & gas, and heavy manufacturing sites.

Precision Environmental Sealing

The enclosure utilizes a CNC-poured Polyurethane (PU) foam-in-place gasket. This continuous seal ensures that even under high-pressure water jets (IP66) or temporary submersion, no moisture or fine particulate matter (dust/sand) can penetrate the internal chamber.

Thermal Management & Safety
  • Heat Dissipation: Optional integrated louvers or fan-filter units can be installed without compromising the IP rating.
  • Grounding System: Standardized M8 earthing studs are welded to both the body and the door to ensure electrical continuity and operator safety.
Industrial Applications
  • Mining & Quarrying: Protecting heavy-duty switchgear from abrasive dust and vibrations.
  • Water Treatment Plants: Resistance to high humidity and corrosive chlorine-based environments.
  • Renewable Energy Hubs: Large-scale solar combiner cabinets and wind turbine control panels.
  • Marine & Offshore: Withstanding salt spray and heavy sea conditions on docks or vessels.
Installation & Configuration
  • Mounting Options: Supports floor-standing plinths or heavy-duty wall-mount brackets.
  • Internal Layout: Features a galvanized mounting plate (2.5mm thickness) for flexible component arrangement.
  • Cable Entry: Removable gland plates at the bottom, secured with gaskets to maintain the airtight seal.
Frequently Asked Questions
Does this cabinet meet international flame retardancy standards?
Yes, the metal construction is inherently non-combustible, and all powder coatings are formulated to meet UL standards for flame resistance.
Can the cabinet be customized with specific dimensions?
We offer a wide range of standard sizes from 300x200mm up to 2000x1200mm. Custom dimensions and specialized cut-outs for HMI displays can be provided based on technical drawings.
How does the IK10 rating benefit my project?
The IK10 rating confirms the enclosure can withstand a 5kg mass dropped from 40cm. This is essential for preventing equipment failure in public areas or high-traffic industrial zones.
