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

Core Unique Advantage

Zero drawing threshold for buyers: No need to prepare CAD drafts. Our structural engineers complete full production-grade drawings for free, unlimited revisions at zero cost, cutting your pre-sourcing engineering cost & waiting period.
Professional outdoor IP65 waterproof & dustproof construction: Integrated rain eaves + double EPDM sealing groove design, stop rainwater, fog and dust penetrating cabinet; anti-condensation internal layout avoids short circuit caused by temperature difference.
High precision sheet metal fabrication: ±0.1mm dimensional tolerance, reinforced anti-deformation ribs, eliminate cabinet sagging, hole misalignment and assembly gap defects common in cheap enclosures.
All-in-house full production chain: Laser cutting, CNC bending, full penetration welding, salt-spray resistant powder coating and finished assembly, no outsourced processes, consistent quality control.
Wide material customization: Cold rolled steel, SS304/316 stainless steel, aluminum alloy optional; customized size, lock structure, ventilation holes, cable ports and internal DIN rail layout.

Pain Points We Solve

Most overseas buyers face frustrating issues when sourcing outdoor power cabinets:

Unable to find suppliers offering free structural design, forced to hire expensive third-party drafters
Cheap cabinets deform easily after installation, leading to messy internal wiring
Ordinary single-layer sealing causes water leakage & rust in coastal, rainy or high-dust areas
Scattered processing vendors lead to inconsistent quality and delayed delivery Our one-stop customized enclosure service fixes all these pain points at once.

Frequently Asked Questions

What is the minimum order quantity?

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?

Yes, we export worldwide with export-grade plywood packaging, and we support FOB, CIF and DDP shipping terms.
