Electrical Enclosure
Electrical Enclosure Manufacturer | Custom Prefabricated Cabin & E-House Enclosures
We manufacture custom electrical enclosures, prefabricated cabin enclosures, and E-Houses for power distribution, renewable energy storage, and industrial control systems. Using CNC laser cutting, robotic welding, and automated powder coating lines, we fabricate enclosures to client engineering drawings. Every enclosure undergoes dimensional checks, IP sealing tests, and coating thickness verification before dispatch.

Drawing Submission: Send 3D models (STEP / IGES) or 2D CAD files (DWG / PDF) showing dimensions, cutout locations, door swing direction, and gland plate details.
Design for Manufacturability (DFM): We review sheet metal bend radii, weld seam locations, weight distribution, and door hinge tolerances. We issue approval production drawings within 24 to 48 hours.
CNC Laser Cutting and Punching: CNC laser cutters process sheet metal with a tolerance of +/-0.1 mm, ensuring accurate cutouts for meters, displays, air conditioners, and cable glands.
CNC Bending and Jig Assembly: Multi-axis CNC press brakes form panels. Dedicated assembly jigs align frame posts and doors to maintain squareness within +/-1.0 mm.
Pre-Assembly and Inspection: We assemble doors, locks, gland plates, and internal mounting rails to verify fitment before paint application.
Manufacturing Process and Quality Control
Precision Laser Cutting and Punching
CNC fiber laser cutters slice steel sheets up to 20 mm thick. Edges remain clean and smooth, so no extra manual grinding is needed.
Robotic and Manual Welding
Workers and robots use MIG or TIG welding to connect frame parts. We fully weld and grind outer corner seams to stop water leaks.
Multi-Stage Surface Pre-Treatment
Steel parts pass through a 7-stage chemical washing line. This process removes oil and rust, which helps paint stick tightly to the metal.
Automated Powder Coating
Automatic spray guns apply outdoor polyester powder evenly on all sides. Then, baking ovens cure the powder at 180 to 200 deg C to make a hard outer coat.
Automated Gasket Foaming
CNC foaming machines apply continuous liquid polyurethane gaskets directly onto door frames. This creates a seamless joint for IP65 water protection.
100% Quality Inspection
We check box dimensions, paint film thickness, paint sticking strength, ground safety, and water spray sealing (IPX5/IPX6 tests) before packing.
Applications
Power Transmission and Distribution
Prefabricated E-Houses and outdoor control enclosures for 11kV to 110kV substations, ring main units, and sectionalizer switchgear.
Renewable Energy Systems
Weatherproof cabin enclosures for solar central inverters, wind turbine base controllers, and battery energy storage container systems (BESS).
Industrial Automation and Manufacturing
Heavy-duty floor-standing cabinets for motor control centers (MCC), variable frequency drives (VFD), and factory power hubs.
Infrastructure and Transportation
Outdoor IP65 control enclosures for railway signaling, highway lighting distribution, traffic monitoring, and EV charging stations.
Packaging & Delivery
Surface and Edge Protection
All painted surfaces are covered with PE protective film. Cardboard corner guards protect enclosure edges from impact during handling.
Moisture Control
Desiccant bags are placed inside the enclosure, and the entire unit is wrapped in VCI anti-rust stretch film or vacuum plastic film.
Heavy-Duty Skids and Crating
Large cabins are mounted on heavy channel-steel transport frames. Smaller enclosures are packed into solid fumigated wooden crates (ISPM-15 compliant).
Container Lashing
Enclosures are secured inside containers using steel cables, turnbuckles, and wood blocking to prevent shift during ocean transport.
