100 Metre Roll of KEY 6B&S Twin Core Automotive Cable for Reliable 12V, 24V, and 48V Power Distribution

High-Performance 13.5mm² Twin Sheath Cable for Caravans, 4WDs, Marine, and Off-Grid Systems

This 100-metre roll of KEY 6B&S (13.5mm²) twin core automotive cable delivers a professional-grade wiring solution for demanding low-voltage installations. Engineered with plain annealed oxygen-free copper conductors, it provides superior conductivity and minimal voltage drop over long cable runs, making it an excellent choice for caravan solar setups, 4WD dual battery systems, marine electronics, and off-grid power distribution. The twin core configuration, with red and black inner insulation, simplifies polarity identification and reduces installation time compared to running two separate single core cables.

Unlike generic automotive cable that may use copper-clad aluminium or lower-grade PVC, this cable features V90HT PVC insulation rated for continuous operation up to 90°C. The durable black outer sheath is UV-stabilised to resist degradation from prolonged sun exposure, ensuring long-term reliability in engine bays, under-vehicle routing, and outdoor environments. With a nominal current rating of 103A at 30°C (per JASO D609), it handles high-demand circuits such as inverters, battery chargers, and DC-DC converters with confidence. *Note typical de-rating factors apply for bundling and elevated ambient temperatures.

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.

Why This Cable Outperforms Standard Options

Selecting the right cable is critical for safety and system efficiency. This 6B&S twin core cable addresses common pain points that installers face with inferior products:

  • Reduced Voltage Drop: The 13.5mm² cross-sectional area and high-purity copper minimise resistive losses, preserving battery voltage for sensitive electronics and maximising charging efficiency from solar panels or alternators.
  • Enhanced Thermal Resilience: V90HT insulation withstands engine bay heat without softening or melting, reducing the risk of short circuits in high-temperature zones.
  • UV and Moisture Resistance: The UV-stabilised outer sheath prevents cracking and embrittlement from sunlight, while the robust construction resists moisture ingress, making it suitable for marine and outdoor use.
  • Compliance and Safety: Manufactured to meet Australian and New Zealand safety standards and RoHS compliant, this cable provides peace of mind for professional installers and DIY enthusiasts alike.

Key Features at a Glance

  • 100-metre continuous roll for large installations or multiple projects, reducing waste and splice points
  • Oxygen-free plain annealed copper conductors (168 strands of 0.32mm) for excellent flexibility and current flow
  • Twin core design with red and black inner insulation for easy circuit identification
  • V90HT PVC insulation rated to 90°C, suitable for engine bay and high-temperature environments
  • UV-stabilised black outer sheath for long-term outdoor durability
  • 103A nominal rating at 30°C (JASO D609), with derating factors for bundled or higher-temperature installations
  • Maximum DC voltage: 120V, suitable for 12V, 24V, and 48V systems
  • Nominal outer diameter: 7.2mm, compact enough for tight conduits and cable runs

Ideal Applications for 6B&S Twin Core Cable

This versatile cable is engineered for a wide range of low-voltage DC applications where reliability and performance are non-negotiable:

  • Caravan and RV Solar Systems: Connect solar panels to charge controllers and batteries with minimal power loss, even on longer roof-to-battery runs.
  • 4WD Dual Battery Setups: Link auxiliary batteries to isolators, fridges, and camping accessories with a cable that handles high current and harsh under-bonnet conditions.
  • Marine Wiring: Power navigation lights, bilge pumps, and onboard electronics with a moisture-resistant cable that withstands salt-laden air.
  • Off-Grid Cabins and Sheds: Distribute power from battery banks to inverters, lighting, and pumps in remote installations.
  • Automotive Lighting and Accessories: Upgrade headlight looms, driving light harnesses, or power inverters with a cable that exceeds standard OEM specifications.

Installation Considerations for Optimal Performance

To achieve the full 103A rating, install this cable in free air at an ambient temperature of 30°C. When bundling multiple cables or operating in hotter environments, apply the appropriate derating factors as outlined in JASO D609. For example, a bundle of three cables reduces the effective current rating to 70% of the nominal value, while an ambient temperature of 50°C requires a 0.76 multiplier. Always select the correct cable size based on your specific load, run length, and installation conditions. Consult a qualified auto electrician for complex installations to ensure compliance with relevant wiring standards.

Upgrade Your Power System with Confidence

Whether you're wiring a new caravan, upgrading a 4WD electrical system, or building an off-grid power setup, this 100-metre roll of KEY 6B&S twin core automotive cable provides the quality and performance needed for a safe, efficient installation. Add it to your cart today and power your next adventure with a cable built for Australian conditions.

Incredible reading
Format: Hardcover
I bought this just before Christmas when a guest speaker talked about it in our church. I immediately looked up and bought it right away. This is a quality book. Hard bound with heavy gloss paper and nice art inside and out. But the real value is inside. I couldn't put it down. If you've ever wanted to know more indepth details about the Christmas story, a detailed and true explanation of the birth of Jesus, this is the book to buy. It's worth every penny. If you've ever had questions like: why those shepherds? what made them so special? details about the "wise men", why do only Luke and Mark detail these events, why Nazareth? and so much more... buy the book! I took my book over my daughter's house for Christmas Eve with her and her kids + a few friends. They aren't all as familiar with scripture as my husband and I are, but I've insisted on continuing the tradition my mom started of reading the Christmas Story before we open any presents. I brought this book and told them a few things covered in the book... like where the manger was. When we left, I offered to leave the book if anyone wanted to look at it... one of the girls excitedly said she was hoping I would leave it. She really wanted to read it. I couldn't have been more thrilled. I would encourage anyone interested in this book to buy it, read it, and give it to someone else who will read it too. For the money, what a great witnessing tool! It's so factual, it will speak to those who are kind of "on the fence".
