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

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 extra-low-voltage DC installations where corrosion resistance and consistent conductivity are critical. Its tinned copper conductors to AS/NZS 1125 resist corrosion in salty, high-humidity conditions better than plain copper wire, making it a dependable choice for coastal, marine and mobile applications. Australian made.

Unlike standard automotive cable, the tinned conductors resist black wire corrosion, a common failure point in untreated copper exposed to moisture. The cores are V90 PVC insulated under a black 5V90 PVC sheath.

Key Features

• Rated 92A in free air at 40°C (AS/NZS 3008.1.1) for high-demand circuits such as battery chargers, inverters and winches; derate when bundled or enclosed
• 168/0.32mm stranded tinned copper conductors to AS/NZS 1125 for flexibility and corrosion resistance
• V90 PVC insulated cores with a black 5V90 PVC sheath (AS/NZS 3808)
• 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

This cable is manufactured to AS/NZS 1125 for the tinned copper wire and AS/NZS 3808 for the insulation and sheath.

Where Performance Matters

This cable is suited to a range of extra-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; the nominal outer size is 8.8 x 16.0mm. Rated 92A to AS/NZS 3008.1.1 (twin-core cable in free air at 40°C ambient), it suits high-demand circuits such as inverters and battery chargers.

*Derating factors apply for bundled cables, enclosure and higher ambient temperatures. Use our cable sizing calculator for your installation.

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.
