Whether you are wiring a dual battery system in a 4x4, installing solar panels on a caravan, or upgrading marine electronics, the quality of your cabling dictates the safety and performance of your entire setup. Manufactured to strict Australian Standards (AS\/NZS 1125 and AS\/NZS 3191), this cable ensures optimal electrical flow and long-term durability in harsh environments.\u003c\/p\u003e\n\u003ch3\u003eAbout KEY Tubing \u0026amp; Electrical\u003c\/h3\u003e\n\u003cp\u003eKEY Tubing \u0026amp; 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.\u003c\/p\u003e\n\u003ch3\u003eSuperior Oxygen-Free High Conductivity (OFHC) Copper\u003c\/h3\u003e\n\u003cp\u003eAt the core of this cable lies Oxygen-Free High Conductivity (OFHC) copper. Unlike standard tough pitch copper, OFHC contains minimal oxygen and impurities, resulting in significantly higher electrical and thermal conductivity. This reduction in internal resistance helps minimise voltage drop—a critical factor when running power to sensitive equipment like DC-DC chargers, inverters, and 12V fridges over long distances.\u003c\/p\u003e\n\u003cp\u003eFurthermore, the OFHC manufacturing process provides excellent resistance to hydrogen embrittlement. Standard copper can become brittle when heated in certain atmospheres, but the high purity of this 7.92mm² conductor ensures it remains flexible and robust, resisting vibration and thermal fatigue common in automotive and marine applications.\u003c\/p\u003e\n\u003ch3\u003eVersatile Voltage Handling: 12V, 24V, and 48V Ready\u003c\/h3\u003e\n\u003cp\u003eWhile often categorised as automotive cable, this product is designed with a maximum DC voltage rating of 120V. This makes it an excellent choice not just for standard 12V systems, but also for 24V truck systems and modern 48V off-grid solar or traction setups. By supporting higher voltage thresholds, it offers a versatile solution for a wide range of DC power distribution needs without the risk of insulation breakdown common in lower-grade wires.\u003c\/p\u003e\n\u003ch3\u003eIndustrial-Grade Durability and Insulation\u003c\/h3\u003e\n\u003cp\u003eThe conductor is protected by V90HT insulation, designed to withstand the rigours of the Australian climate. This high-temperature insulation ensures the cable maintains its integrity even in engine bays or hot roof cavities where temperatures fluctuate. With a substantial current rating of 74A at 30°C, this 8B\u0026amp;S cable provides ample overhead for heavy loads. Users should always consider typical de-rating factors for bundling and ambient temperature to ensure the 74A maximum current capacity meets the specific installation requirements.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Conductivity:\u003c\/strong\u003e OFHC copper construction minimises voltage drop and power loss.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Resistant:\u003c\/strong\u003e V90HT insulation rated for high-temperature environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Versatility:\u003c\/strong\u003e Rated up to 120V DC, suitable for 12V, 24V, and 48V configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompliance:\u003c\/strong\u003e Manufactured to AS\/NZS 1125 and AS\/NZS 3191 standards.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy Identification:\u003c\/strong\u003e Industry-standard black colour coding for simplified polarity identification.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSafe and Reliable Installation\u003c\/h3\u003e\n\u003cp\u003eThis single-core cable is ideal for looming into custom harnesses or running through conduit for protected installations.
