How do you prevent water ingress at cable entry points?

Cable entries use sealed glands with rubber grommets positioned at the bottom or side as specified, combined with internal drip channels to route condensation away from equipment.

Product Overview

1. Product Overview

Our power distribution cabinets and control boxes are high-standard sheet metal products designed for electrical power systems, industrial control, and renewable energy applications. Unlike ordinary electrical enclosures, our cabinets feature reinforced structural design, strict safety standards, and customized internal layouts to accommodate complex electrical components. We specialize in manufacturing complete control distribution panels, grid-tie cabinets, and base enclosures, providing reliable mechanical protection, electromagnetic shielding, and environmental isolation for core power equipment.

2. Key Advantages

✅ High Structural Rigidity & Durability

Thickened industrial-grade steel plates and reinforced frame design ensure strong load-bearing capacity and deformation resistance, suitable for long-term stable operation in harsh industrial environments.

✅ Customizable IP Protection Levels

IP54/IP55/IP65 ratings available, with anti-corrosion powder coating treatment to resist dust, moisture, and chemical corrosion, extending service life in outdoor and high-humidity scenarios.

✅ Precision Manufacturing & Perfect Assembly

Adopt laser cutting, CNC bending, and precision welding processes, with strict tolerance control to ensure accurate hole positions and consistent assembly gaps, perfectly matching electrical components and wiring systems.

✅ Full OEM/ODM Customization Support

Custom sizes, special-shaped structures, internal mounting brackets, hole layouts, surface colors, and logo engraving are available. Our engineering team can optimize designs based on customer drawings to improve heat dissipation and structural stability.

3. Manufacturing Process

Laser Cutting: Burr-free cutting and precise hole positioning for complex outlines and mounting holes
CNC Bending: Accurate angle control to ensure uniform cabinet structure and assembly fit
Welding & Polishing: Seamless welding and grinding to enhance structural strength and tightness
Surface Treatment: Degreasing, phosphating, and electrostatic powder coating for durable anti-corrosion protection
Assembly & Testing: Full inspection of dimensions, protection level, and structural integrity before delivery

4. Applications

Power distribution systems and low/high voltage power control
Industrial automation equipment and control panels
Renewable energy grid-tie cabinets and energy storage systems
Factory workshops, outdoor power stations, and industrial facilities
Complete electrical distribution panels and base enclosures

😩 Typical Buyer Pain Points

MOQ is 1 piece. We welcome prototype and small-batch orders so you can validate the design before scaling up.

Can you design the cabinet if we don't have drawings?

Yes. Free production-ready CAD drawing design is our core service. Provide your power module dimensions, weight and layout requirements, and our engineers will produce manufacturable drawings for your confirmation.

What drawing formats do you accept?

We accept STEP, IGS, DWG, DXF and PDF sketches. Even a hand sketch with key dimensions is enough to start.

How do you quote? What are the payment terms?

Factory-direct quotation within 24 hours of receiving your requirements. Payment by T/T (30% deposit, 70% before shipment). FOB, CIF and DDP shipping terms supported.

What is the typical lead time?

Samples take 7–10 days; mass production takes 15–25 days depending on quantity and surface treatment requirements.

Can the cabinet achieve IP55 or higher protection?

Yes. Our standard sealing design reaches IP54–IP55, and we can upgrade gaskets, cable glands and door structures for harsher environments.

Do you ship internationally?
