Top 7 Electrical Harness Manufacturers and Suppliers

A wiring harness is an electrical wire sheath that protects and organizes several different types of cables. Wire harnesses are typically made from thermoset or thermoplastic materials and can protect cables from environmental hazards. Materials including polyvinyl chloride, vinyl, TPE, polyurethane (PU), and PE all yield a variety of colors and sizes that find use in industries such as forklifts, the military, and the aviation industry.

A wiring loom is the best option when a bundle of wires with separate connectors would take up too much room. Wires are more resilient in the form of bundles. Therefore wire harnesses find applications in places where vibration might ordinarily affect the performance of individual wires. The suppliers of electric wiring loom and wire harness assembly are the subject of this article.
