30m Roll of 6B&S (13.5mm²) Twin Core Marine Tinned Cable for Reliable DC Power

Engineered for Harsh Marine and Off-Grid Environments

This 30-metre roll of 6B&S (13.5mm²) twin core marine cable is purpose-built for demanding 12V, 24V, and 48V DC installations where corrosion resistance and consistent conductivity are critical. The tinned copper conductors resist oxidation in salt-laden air and high-humidity conditions, making it a dependable choice for coastal, marine, and mobile applications.

Unlike standard automotive cable, each strand is individually tinned to prevent black wire corrosion, a common failure point in untreated copper exposed to moisture. The dual-layer RoHS-compliant 5V90 PVC insulation and sheath provide robust protection against UV, oil, and abrasion, ensuring long-term reliability in engine bays, bilge areas, and exposed outdoor runs.

Key Features

• 82A current rating (JASO D609 at 30°C) for high-demand circuits such as battery chargers, inverters, and winches
• Tinned copper conductors to AS/NZS 1125 prevent corrosion and maintain low resistance over time
• UV-stabilised 5V90 PVC sheath resists cracking and degradation from sun exposure
• Red and black core identification simplifies polarity matching during installation
• 30-metre continuous roll reduces joins and voltage drop across longer cable runs

Built to Australian Standards

Manufactured to AS/NZS 1125 for tinned copper wire and AS/NZS 3808 for insulation, this cable meets stringent safety and performance benchmarks. The 5V90 PVC compound is flame-retardant and oil-resistant, adding an extra layer of protection in confined spaces like engine compartments or battery enclosures.

Where Performance Matters

This cable is suited to a range of low-voltage DC applications where reliability cannot be compromised:

• Marine battery banks and switch panels
• Solar charge controller to battery connections
• Electric winches and anchor windlasses
• Caravan and RV auxiliary power systems
• Off-grid cabin and shed wiring

The 13.5mm² cross-sectional area (equivalent to 6 AWG) balances current capacity with flexibility, allowing routing through tight conduits and cable glands without excessive stiffness. At 82A maximum rating, it handles typical loads for mid-sized inverters and battery chargers, though derating factors for bundling and elevated ambient temperatures should be applied as per the JASO D609 standard.

*Note typical derating factors apply: when multiple cables are bundled or ambient temperatures exceed 30°C, the safe current carrying capacity reduces. Refer to the derating tables in the specifications for guidance.

Reduce Installation Risks

Using non-tinned cable in marine or coastal settings often leads to premature failure, intermittent connections, and increased fire risk from high-resistance joints. This tinned cable mitigates those risks by maintaining low electrical resistance (1.42 ohm/km at 20°C) and resisting the corrosive effects of salt spray and condensation. The robust sheath also withstands mechanical wear, reducing the chance of insulation breaches that can cause short circuits.
