6mm (4.59mm²) Twin Core Automotive Cable per Metre

Austech 6mm (4.59mm²) Twin Core Automotive Cable for Reliable Low-Voltage Power

When you’re wiring a vehicle, trailer, caravan or 4WD accessory, cable quality directly affects performance, safety and long-term reliability. This Austech 6mm (4.59mm²) twin core automotive cable is built for demanding Australian conditions, combining high-conductivity copper with a tough, UV-stabilised PVC sheath to help protect against abrasion, heat and day-to-day vibration.

Because it’s twin core, you can run positive and negative together in a neat, protected jacket—ideal for cleaner installs and easier fault-finding. Colour-coded inner cores also help reduce wiring errors, which can be especially valuable when you’re working on tight deadlines or troubleshooting under load.

Engineered to Reduce Voltage Drop and Heat Build-Up

In real-world automotive and recreational setups, voltage drop is a common cause of dim lights, slow charging, nuisance low-voltage cut-outs and underperforming accessories. Using a quality copper conductor helps support efficient current flow so your 12V wiring and accessory circuits operate as intended. For best results, match the cable to your run length and current draw, and follow accepted installation practices for routing and protection.

Built Tough for Outdoor and Under-Bonnet Environments

The UV-stabilised V90HT PVC insulation and sheath are designed to handle harsh sun exposure and elevated temperatures encountered in automotive and outdoor installations. The multi-strand copper construction also improves flexibility, making it easier to route through conduits, behind panels and around tight bends without fighting the cable.

Ideal for Automotive, Marine-Adjacent and Recreational Applications

This cable is well suited to a wide variety of automotive wiring and low-voltage power tasks, including dual battery systems, caravan accessories, trailer wiring, 4WD lighting and accessory circuits such as fridges, LED lighting and water pumps where a robust twin core cable helps keep installations tidy and dependable. It’s also a practical choice when you want a consistent, easy-to-identify polarity layout throughout a build.

Standards-Aligned Materials for Added Confidence

Made with plain annealed copper conductors to AS/NZS1125 and PVC compounds to AS3808, this cable is designed with compliance and consistency in mind. It is also RoHS compliant. Amp ratings shown in the specifications are based on an established automotive test method (JASO) and should be considered alongside your installation environment, bundling, ventilation and duty cycle.
