Harness Braiding

Electrical wire Braiding Service

Braid is composed of PVC coated nylon threads woven tightly around an electrical harness/loom. Braiding is important for electrical harnesses as it extends the service life of harnesses by providing a protective layer from chafing, heat, oil, antifreeze, hydraulic fluid, cold flexibility, fire resistance, moisture and other wear and tear to electrical harnesses. It also provides a uniform surface.

We stock two High-Performance ranges of yarn: VN-4400S & VN-4000S. Vinyl coated nylon yarn performs at higher temperatures for extended periods while retaining the properties of high fire retardancy, abrasion and oil resistance. Meets MVSS 302, SAE J369, UL94 V-0 at 125 mL.
