6B&S (13.5mm²) Twin Core Marine (Tinned) Cable per Metre

6B&S (13.5mm²) Twin Core Marine Tinned Cable: Engineered for Harsh Marine Environments

Reliable Power Delivery for Marine and Mobile Applications

This 6B&S (13.5mm²) twin core marine cable delivers consistent, low-resistance power where moisture and salt are a concern. Its tinned copper conductors to AS/NZS 1125 resist corrosion better than plain copper wire, which suits marine electrical systems, coastal installations and RVs. The cores are V90 PVC insulated under a black 5V90 PVC sheath, both to AS/NZS 3808. Australian made.

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 battery winches, chargers, inverters and solar generator connections. Red and black cores make polarity matching simple and reduce wiring errors. *Derating factors apply for bundled cables, enclosure and higher ambient temperatures.

Why Tinned Copper Matters

In marine and coastal environments, untreated copper wire is prone to oxidation and corrosion, which increases electrical resistance and can lead to system failures. The tinned copper wire (TCW) in this cable resists corrosion from saltwater and humidity better than plain copper, helping it keep its low resistance over time. This matters for marine tinned wire used in bilge pumps, navigation lights and communication equipment.

Built for Versatility

While optimised for marine cable applications, this 6B&S twin core cable is equally effective in automotive, caravan and off-grid solar setups. It suits 12V, 24V and 48V extra-low-voltage DC systems, making it a versatile choice for dual battery systems, solar panel wiring and auxiliary power circuits.

Installation Confidence

This cable is sold per metre, allowing you to order the exact length required for your project. The flexible stranded design eases installation around corners and through conduits. For best results, pair it with correctly sized tinned lugs and adhesive-lined heat shrink to keep the connection watertight and resistant to corrosion.
