2B&S (32mm²) Black Single Core Marine Cable (Tinned) per Metre
Black 190A Rated 32mm² Tinned Copper Cable for Marine & Dual Battery Systems

DESCRIPTION
High-Performance 2B&S (32mm²) Tinned Copper Cabling for Marine and Automotive Systems
The Black 2B&S (32mm²) Tinned Copper Marine Cable is engineered to deliver uncompromising power transfer in the harshest environments. Designed specifically for marine vessels, 4WD dual battery setups, and off-grid power systems, this cable combines high-conductivity oxygen-free copper with durable insulation to ensure your electrical system performs reliably for years to come.
Unlike standard copper cabling that degrades rapidly when exposed to salt air and moisture, this premium Black 2B&S (32mm²) Tinned Copper Marine Cable features fully tinned conductors. This tin coating creates a robust barrier against oxidation and "black wire" corrosion, ensuring low resistance and consistent voltage delivery to critical components like inverters, winches, and start batteries.
Superior Current Handling and Heat Resistance
With a substantial 32mm² cross-sectional area (2 B&S), this cable is capable of handling high current loads up to 190A, making it the ideal choice for minimizing voltage drop over long runs. The conductor is encased in professional-grade V90HT insulation, which provides exceptional resistance to heat, abrasion, and chemicals found in engine bays and bilges.
*Note: The 190A current rating is based on single-core usage at 30°C ambient temperature; typical de-rating factors apply for bundled cables or higher operating temperatures.
Versatile Application: 12V, 24V, and 48V Systems
While frequently sought after for 12V automotive cable and marine applications, this cabling is rated for a maximum of 120V DC. This makes it perfectly suitable for modern 24V truck systems and 48V off-grid battery banks, ensuring safety and compliance across a wide range of DC voltages. Whether you are wiring a bow thruster, a DC-DC charger, or a solar regulator, this cable offers the flexibility and safety margin required for professional installations.

Features:
- OFHC (oxygen free high conductivity copper) is employed in audio and industrial electronic units.
- High electric and thermal conductivity. Since OFHC contains oxygen and impurities in very small quantities only, it shows excellent electric conductivity and thermal conductivity (Oxygen and impurities reduce the conductivity)
- Excellent hydrogen enbrittlement resistance (TPC) Tough pitch copper becomes very brittle when it is heated at higher then 600C under a reduction gas atmosphere including hydrogen gas. Since OFHC contains a very low oxygen content only, it does not show any brittleness
