Product Overview

This High-voltage Metal Cable Cubby Enclosure is protected by a uniform, gloss black E-coating (electrophoresis). The precision-engineered chassis features numerous cutouts and mounting points, designed for the secure installation of power electronics, connectors, and cable glands. The advanced E-coating finish ensures comprehensive coverage, even on complex internal surfaces, providing exceptional resistance to corrosion, humidity, and chemical exposure. Its robust, heavy-gauge steel construction guarantees durability and reliable protection for sensitive high-voltage components in demanding industrial or automotive environments.

Key Features & Advantages

 

Superior E-Coating Finish: Utilizes an automotive-grade cathodic electrophoresis process. This finish offers exceptional adhesion and provides a uniform coating that covers every surface, including internal cavities, sharp edges, and complex geometries, delivering best-in-class resistance to corrosion, salt spray, and chemicals.

High-Precision Fabrication: Relies on advanced laser cutting, CNC punching, and CNC bending to guarantee the precise dimensions of all apertures, mounting holes, and assembly points. This dimensional accuracy is critical for the proper installation of internal high-voltage components and harnesses.

Excellent Insulation & Protection: The E-coating layer itself provides excellent electrical insulation properties. Combined with the robust metal structure, it effectively prevents current leakage and protects internal components from environmental interference, ensuring safe system operation.

One-Stop Custom Fabrication Service: A complete sheet metal fabrication service is offered, from rapid prototyping to high-volume production. Clients provide a drawing or requirements to receive a complete, finished product solution, including cutting, bending, welding, e-coating, and silk-screening.
