The Oxygen-Free Copper Advantage

Not all copper cables are created equal. This series utilises OFHC copper, which is refined to remove oxygen and impurities that typically impede electron flow. In standard "tough pitch" copper, impurities can lead to increased resistance and heat generation under load.

Furthermore, OFHC copper exhibits exceptional resistance to hydrogen embrittlement. In high-temperature environments or specific atmospheric conditions, standard copper can become brittle and prone to cracking, leading to circuit failure. By choosing OFHC, you are investing in a conductor that maintains its mechanical integrity and flexibility, ensuring long-term reliability even in vibrating vehicle chassis or engine bays. This high purity also makes it an excellent choice for high-fidelity car audio installations where signal integrity and power stability are paramount.

Engineered for High-Current 12V, 24V, and 48V Systems

While commonly used for 12V automotive applications, the specifications of this cable allow for much greater versatility. Rated for a maximum DC voltage of 120V, this cable is fully compatible with modern 24V truck systems and emerging 48V lithium battery banks. The substantial 190A current rating (at 30°C) allows it to handle significant power surges from starter motors and sustained loads from inverters or DC-DC chargers. Using an undersized cable for these applications can result in dangerous overheating and significant power loss.

*Typical de-rating factors apply relative to ambient temperature and installation grouping.

Australian Standards Compliance and Durability

Safety and compliance are non-negotiable in professional installations. This cable is manufactured to AS/NZS 1125 for the conductor and AS/NZS 3808:2000 for the insulation material. The V90 grade insulation is capable of withstanding operating temperatures up to 90°C, providing a critical safety margin in hot engine compartments.

The outer sheath is durable yet flexible, with a nominal outer diameter of 10.7mm. It resists abrasion, oil, and common automotive chemicals. The internal conductor consists of 455 strands of 0.30mm wire, a configuration that offers the perfect balance between flexibility for routing through tight grommets and the density required for heavy current carrying capacity.
