OFHC Copper for Maximum Efficiency and Performance

This 26mm² single core automotive cable features premium OFHC copper conductors that minimise resistance and maximise current flow. Compared to standard copper cable, OFHC copper contains fewer impurities, resulting in improved electrical efficiency, reduced heat generation, and lower voltage loss across long cable runs. This makes it an ideal choice for applications where stable voltage and reliable power transfer are essential.

The high-purity copper construction also improves flexibility and resistance to fatigue, helping the cable maintain its integrity in environments exposed to vibration, movement, and temperature fluctuations. From engine bays and battery compartments to marine vessels and industrial equipment, this cable is built for long-term performance.

Suitable for High-Current Power Distribution Applications

With a substantial 26mm² conductor size (3B&S) and a typical current rating of 170A, this cable is designed to handle significant electrical loads while maintaining efficient power delivery. Suitable for systems up to 120V DC, it supports a wide range of modern electrical installations including 12V automotive systems, 24V truck applications, and 48V lithium battery setups.

Popular Applications Include:

• Dual battery systems in 4WDs, caravans and camper trailers
• Positive battery interconnect and auxiliary battery wiring
• DC-DC charger installations and lithium battery banks
• High-current inverter and solar power systems
• Marine electrical systems and vessel battery banks
• Commercial vehicle, fleet and industrial power distribution

Manufactured to Australian Standards

Safety and reliability are critical for every electrical installation. This cable is manufactured in accordance with AS/NZS 1125 conductor standards and AS/NZS 3808:2000 insulation requirements. The durable V90 insulation is rated for operating temperatures up to 90°C and provides excellent resistance to abrasion, oils, fuels, and common automotive chemicals.

The flexible multi-strand construction allows easier routing through engine bays, chassis rails, conduits, and switchboards while maintaining excellent current-carrying performance. The red outer sheath provides clear identification for positive power circuits, simplifying installation and maintenance.
