Wiring harnesses tough enough to withstand even the most extreme mine site conditions

Need a custom-made wiring harness, or a quality OEM alternative solution?

Repeated exposure to dirt, moisture and high vibrations are a real challenge for heavy mining equipment. Our wiring harnesses are built to endure the harshest conditions our planet has to offer. Our custom-made wiring harnesses are the best in the business. Let’s take a look at why…

Quality is key

We use only the highest quality connectors and specifically engineered cabling. This ensures our wiring systems are durable and have longevity. In the long run, this saves both time and money – your operation will remain on-time and on-budget.

We’ve been supplying the mining industry for a long time and we understand how important this is to you. (It’s important to us, too!)

You may be wondering what the secret is to making our products so robust. The answer?


We use high performance yarns sourced from the industry leaders to manufacture our harnesses. Our yarns are proven to be exceptional performers at withstanding repeated use while also being moisture- and abrasion-resistant. They are:

  • Rated to 138°C
  • Fire retardant
  • Self-extinguishing
  • Halogen-free
  • Flexible in cold conditions
  • Resilient against engine fluids


The premium wire we use is made from bare copper (or tinned copper for highly corrosive conditions) and is rated from as cold as -40˚c right up to 125˚c.


Our wiring systems are constructed using genuine high quality connectors and terminals including Deutsch, Tyco, Amphenol, ITT Cannon.
