OEX ACX0799L 2mm Twin Core Automotive Cable, Red/Black, With Black Sheath - 100m Roll

OEX ACX0799L Australian Made 2mm Twin Core Automotive Cable Red and Black in One Sheath 100m Roll OFHC Copper 5A V90

The OEX ACX0799L is a 100m roll of 2mm twin core automotive cable, featuring two separately insulated conductors (red positive and black negative) enclosed in a single black outer sheath. Running both supply and return in one cable simplifies wiring for trailer lighting harnesses, automotive accessory circuits, auxiliary lighting runs and any application where a single neat cable run is preferable to routing two separate singles. Made from oxygen free high conductivity (OFHC) copper, rated to V90 (90°C), UV stabilised and RoHS compliant. Rated at 5A at 30°C, suited to low to moderate current loads including trailer lighting, LED strip runs and general purpose automotive signalling circuits.

Product overview

Twin core cable contains two separately insulated conductors inside a single outer sheath, delivering a complete circuit in one cable run. The ACX0799L uses red for the positive conductor and black for the negative or earth conductor, following the standard automotive wiring colour convention. Routing one twin core cable instead of two separate singles reduces installation time, simplifies cable management and produces a neater, more professional finished wiring run. This makes the ACX0799L particularly well suited to trailer lighting harnesses, caravan wiring runs, LED accessory feeds and low-current sensor and signalling applications.

The OFHC copper conductors use less than 0.001% oxygen content, minimising resistance and reducing oxidation over time for consistent current transfer across the full 100m roll. The UV stabilised black outer sheath resists cracking, hardening and degradation from prolonged sun exposure, important for cable runs on trailer chassis, caravan exteriors and any exposed routing in Australian outdoor environments. The 100m roll format suits trade workshop supply, fleet wiring projects and large-scale trailer harness builds where consistent cable specification across the entire job is required.

Features and benefits

Twin core configuration, red and black in one sheath: Two separately insulated conductors enclosed in a single black outer sheath. One cable run delivers a complete circuit, eliminating the need to route and secure two separate single-core cables and significantly reducing installation time on trailer harnesses and accessory wiring runs.

OFHC copper conductors: Less than 0.001% oxygen content minimises resistance, reduces oxidation over time and ensures consistent current transfer across the full 100m roll.

5A rated at 30°C: Confirmed current carrying capacity at 30°C ambient temperature, suited to trailer lighting circuits, LED accessory feeds, signalling wiring and low to moderate current automotive applications. Current carrying capacity reduces at ambient temperatures above 30°C.

V90 temperature rating (90°C): The insulation is rated to the Australian V90 standard, withstanding sustained temperatures of 90°C, suited to vehicle tray and trailer installations where ambient heat can be significant.

UV stabilised outer sheath: The black outer sheath resists cracking, hardening and degradation from prolonged sun exposure, suited to exposed cable runs on trailer chassis, caravan bodies and vehicle trays in Australian conditions.

RoHS compliant: Confirms the cable is free from restricted hazardous substances including lead, cadmium and mercury.

Australian owned and made: Manufactured in Australia to local quality standards, ensuring material traceability for professional auto electricians and fleet operators.

100m roll: Trade format suited to workshop supply, fleet wiring projects and large-scale trailer harness builds. Consistent cable specification across the entire job from a single roll.

Frequently asked questions

What does twin core cable mean and why use it instead of two separate singles? Twin core cable contains two separately insulated conductors inside a single outer sheath. Running one twin core cable instead of two separate single-core cables simplifies installation, reduces the number of cable management steps and results in a neater, more professional finished wiring run. The ACX0799L uses red for positive and black for negative, following standard automotive colour convention.

What current can the ACX0799L carry and is it suitable for trailer lighting? The ACX0799L is rated at 5A at 30°C ambient temperature, suited to trailer lighting circuits, LED strip feeds and low-current accessory wiring. Confirm that the total current draw of your circuit does not exceed 5A, and note that carrying capacity reduces at higher ambient temperatures.

Is this cable suitable for outdoor, exposed caravan and trailer wiring? Yes. The UV stabilised black outer sheath and V90 rated insulation make the ACX0799L well suited to outdoor, exposed cable runs on trailer chassis, caravan bodies and vehicle trays, resisting UV degradation and sustained heat common in Australian outdoor environments.

Why does the current rating specify 30°C specifically? Current carrying capacity is temperature dependent. At higher ambient temperatures, cables carry less current safely before the insulation reaches its rated limit. The 5A rating at 30°C is the confirmed baseline. For installations in hotter environments such as underbonnet applications, confirm the appropriate current limit with OEX or a licensed auto electrician before use.

Can this cable be used alongside the OEX single-core battery cables in the same installation? Yes. The ACX0799L suits low-current signalling and lighting circuits at 5A. The OEX single-core cable range covers higher-current battery and primary power feeds at larger gauges. Using both in the same installation allows cable gauge to be matched precisely to each circuit's current requirements.
