KEY - 6B&S (13.5mm²) Twin Core Marine (Tinned) Cable - Australian Made - 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 is purpose-built to deliver consistent, low-resistance power in the most demanding conditions. Constructed with tinned copper conductors to AS/NZS 1125, it offers superior corrosion resistance compared to standard copper wire, making it an excellent choice for marine electrical systems, coastal installations, and any application where moisture and salt exposure are a concern. The RoHS compliant 5V90 PVC insulation and sheath (to AS/NZS 3808) provide robust protection against UV, oil, and flame, ensuring long-term durability both above and below deck.

With a current rating of 82A at 30°C (JASO D609), this cable is well suited for high-demand circuits such as battery winches, chargers, inverters, and solar generator connections. The red and black core identification simplifies polarity matching during installation, reducing the risk of wiring errors. *Note typical de-rating factors apply for elevated temperatures and bundling.

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 forms a protective barrier against saltwater and humidity, maintaining high conductivity and extending the service life of your electrical system. This is particularly critical for marine tinned wire used in bilge pumps, navigation lights, and communication equipment where reliability is non-negotiable.

Key Features

• Dual-layer RoHS compliant 5V90 PVC insulation and sheath for UV, oil, and flame protection
• Red and black cores for clear polarity identification
• Nominal O.D. 8.8 x 16.0mm for easy routing in tight spaces
• Electrical resistance 1.42 ohm/km at 20°C for efficient power transfer

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 is suitable for 12V, 24V, and 48V DC systems (maximum DC voltage 120V), making it a versatile choice for dual battery systems, solar panel wiring, and auxiliary power circuits. The robust black sheath resists abrasion and chemicals, ensuring reliable performance in engine rooms, cable trays, and exposed outdoor runs.

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, while the durable sheath withstands the mechanical stresses typical of mobile and marine environments. For optimal results, pair with appropriately sized marine-grade lugs and heat shrink terminals to maintain a watertight, corrosion-resistant connection.
