Superior Oxygen-Free High Conductivity (OFHC) Copper

At 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.

Furthermore, 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.

Versatile Voltage Handling: 12V, 24V, and 48V Ready

While 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.

Industrial-Grade Durability and Insulation

The 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&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.

Key Features

• High Conductivity: OFHC copper construction minimises voltage drop and power loss.
• Temperature Resistant: V90HT insulation rated for high-temperature environments.
• Voltage Versatility: Rated up to 120V DC, suitable for 12V, 24V, and 48V configurations.
• Compliance: Manufactured to AS/NZS 1125 and AS/NZS 3191 standards.
• Easy Identification: Industry-standard black colour coding for simplified polarity identification.

Safe and Reliable Installation

This single-core cable is ideal for looming into custom harnesses or running through conduit for protected installations. While perfect for extra-low voltage applications, please note that this cable is not suitable for mains connection. Whether you are a professional auto-electrician or a DIY enthusiast outfitting a camper trailer, choosing this premium 100m Roll of 8B&S Black Single Core Automotive Cable ensures your electrical system performs safely and efficiently for years to come.
