ELECTRICAL WIRING HARNESS SERVICE

What is a Cable Harness?

A cable harness, also known as a wire harness, cable assembly, wiring assembly or wiring loom, is an assembly of electrical cables or wires. The cables are bound together by a durable material such as rubber, vinyl, electrical tape, conduit, a weave of extruded string, or a combination of these.

   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.

Our Testimonials

Hear what our customers have to say.

Great service. The team really know what they are doing I take a number of cars to them.

Jordan Clemence

HM Auto Electrical have done almost all our auto electrical work from Utes to trucks. Michael’s work is second to none, expertly completed and never had failures to any installations or work undertaken. He is a perfectionist and thorough where reliability is always been a mark of his. From professional wiring to compliant and safe electrical work, I am always happy to bring something over when we need it.

I had a WOF done on a small trailer today. The staff member I dealt with could not have been more pleasant. The WOF was very reasonably priced as well. I will go back and have no hesitation recommending them.

Brilliant service.I was in the area, plant shopping, after failing a WOF for a blown headlight bulb in central ChCh.I rang them... 'Any chance you could have a look at it now for me, please ?' They said they could. I rocked up and 5 minutes and $10 later including bulb and fitting, I was done.Lovely chap. Bringing old school customer service back to our chaotic world.They deserve to do well.
