KEY 5mm (2.9mm²) Twin Core Automotive Cable: Premium 29A Twin Core Wiring for Demanding DC Applications
The KEY 5mm (2.9mm²) Twin Core Automotive Cable acts as the backbone of reliable low-voltage electrical systems. Engineered with 2.9mm² Oxygen Free High Conductivity (OFHC) copper conductors, this 100m roll delivers consistent power transmission for automotive, marine, and off-grid setups. Unlike standard general-purpose wires, this cable is built to resist vibration, temperature extremes, and environmental stress, ensuring your electrical accessories operate at peak performance.
About KEY Tubing & Electrical
KEY Tubing & Electrical (KTE) is an Australian-owned manufacturer with over 60 years of industry experience supplying electrical, cable, tubing, and custom-engineered solutions to industries across Australia and around the world. Based in South Australia, KEY is known for its commitment to quality manufacturing, rigorous quality standards, and reliable products designed for demanding automotive, electrical, industrial, and resource sector applications. KEY continues to support Australian industry with a strong focus on performance, durability, and dependable engineering.
Superior Conductivity with OFHC Copper
At the core of this cable is 99.9% oxygen-free copper. This high-purity material offers superior electrical conductivity compared to recycled or standard tough pitch copper, resulting in lower voltage drop over long cable runs—critical for maintaining the efficiency of fridges, pumps, and DC-DC chargers. Furthermore, OFHC copper resists embrittlement over time, maintaining flexibility and structural integrity even in high-vibration automotive environments.
Engineered for Heat and UV Resistance
Australia’s harsh climate demands insulation that can survive the elements. This cable features V90HT (High Temperature) PVC insulation, rated to 90°C, preventing the jacket from softening or melting in hot engine bays or enclosed canopies. The UV-stabilised black outer sheath provides a durable barrier against sun damage, oil, and grease, making it an excellent choice for external trailer wiring, solar interconnects, and exposed chassis runs.
Safe for 12V, 24V, and 48V Systems
While perfectly suited as 12V automotive cable, the high insulation breakdown voltage allows for safe operation up to 120V DC. This makes the cable highly versatile for 24V commercial vehicle wiring and 48V lithium battery systems found in modern caravans and off-grid homes. By handling higher voltages safely, it ensures future-proof installations for evolving energy needs.
Streamlined Installation
Professional installers and DIY enthusiasts alike value the easy-strip outer sheath and clearly colour-coded Red and Black cores, which minimize polarity errors and speed up termination. The twin-core construction provides a neat, single-cable run, eliminating the mess of taping separate wires together and offering additional mechanical protection against chaffing.
Key Features
- High-Purity OFHC Copper: 2.9mm² conductors ensure maximum conductivity and reduced resistance.
- High Current Capacity: Rated for 29A (subject to de-rating) to support heavy-duty accessories.
- V90HT Insulation: Withstands continuous operating temperatures up to 90°C.
- UV-Stabilised Sheath: Resists cracking and fading in direct sunlight.
- Wide Voltage Range: Suitable for 12V, 24V, and 48V DC applications (Max 120V).
- Compliance: Meets AS/NZS 1125 and AS 3808 standards; RoHS compliant.
*Typical de-rating factors apply based on ambient temperature, bundling, and run length; ensure cable sizing accounts for voltage drop in your specific installation.
Secure Your Electrical Connections
Don't compromise on your wiring infrastructure. Equip your workshop or project with the KEY 5mm (2.9mm²) Twin Core Automotive Cable for a professional, long-lasting finish. Whether outfitting a 4WD for touring or wiring a marine console, this cable delivers the durability and performance required for critical DC circuits.
