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

Austech 6mm (4.59mm²) Twin Core Automotive Cable per Metre – Built for Dependable 12V/24V/48V Wiring

When you’re running low-voltage power in a 4WD, caravan, trailer or canopy build, the cable you choose can directly affect voltage drop, heat build-up and long-term reliability. The Austech 6mm (4.59mm²) Twin Core Automotive Cable per Metre is a professional-grade twin core automotive cable designed for demanding Australian conditions, with a tough UV-stabilised PVC sheath and high-conductivity copper to support stable power delivery.

The twin core (twin sheathed) design keeps positive and negative together inside one outer jacket, helping you achieve a cleaner install, faster routing and simpler fault-finding. With red and black colour-coded cores, polarity identification is straightforward during installation and maintenance—particularly useful when you’re working under time pressure or tracing a circuit in tight spaces.

Designed to Help Reduce Voltage Drop in Real-World 12V Circuits

In touring and recreational setups, voltage drop is a common cause of dim lights, low-voltage cut-outs, poor fridge performance and slow charging at the load. Using quality copper conductors and selecting an appropriate cable size for your run length and current draw helps minimise losses so accessories operate as intended. This cable is suited to 12V wiring and is also commonly used in 24V and 48V systems where the voltage remains within the product’s low-voltage rating (refer to specifications and applicable wiring standards for your application).

Durability for Vehicles, Trailers and Outdoor Installations

Austech uses UV-stabilised V90HT PVC for the insulation and outer sheath to better handle sun exposure, elevated temperatures and day-to-day abrasion. The flexible multi-strand copper construction makes it easier to pull through conduit, route behind trims, and follow chassis or cabinetry runs—without fighting the cable on tight bends. This can reduce installation time and help lower the risk of insulation damage that may occur with stiffer, lower-quality conductors.

Standards-Aligned Materials for Added Confidence

The conductors are made from plain annealed copper to AS/NZS 1125, with PVC compounds to AS 3808, and the cable is RoHS compliant. Amp ratings shown in the specifications are based on an established automotive test method; in practice, current capacity can be affected by installation conditions such as bundling, ambient temperature, ventilation, duty cycle and how the cable is routed. Where relevant, treat the listed amp rating as a maximum and apply appropriate de-rating and circuit protection.
