Marine Single-Core Copper Cable with PVC Insulation (1–6 mm²)

A high-quality flexible single-core cable certified for marine use, ensuring a long-lasting and safe electrical system on your boat or yacht. The multi-strand copper conductor provides low resistance and vibration resilience, which is crucial as the vessel moves. The special PVC insulation is formulated to withstand intense sunlight, salty seawater, and mechanical stress, preserving the cable’s integrity over years of service. This cable is flame-retardant (self-extinguishing) and resistant to oil and fuel – an important feature for wiring in engine compartments or around engines. It’s suitable for all onboard electrical systems: from navigation electronics and lighting to pumps and refrigerators. Multiple cross-sections (1 mm², 1.5 mm², 2.5 mm², 4 mm², 6 mm²) are available, in two color options (red for positive and black for negative), which makes correct polarity identification and cable tracing much easier.

Recommended uses by cross-section:

• 1 mm²: For low-current consumers and short runs – interior lighting, indicator LEDs, sensors (loads up to ~5–10 A). Ideal for small boats and low-power devices
• 1.5 mm²: A general-purpose size for lighting circuits, small circulation pumps, horns, and other medium-power consumers (up to ~15 A). Commonly used on 4–6 m boats for lights, navigation instruments, etc.
• 2.5 mm²: For moderate loads – suitable for higher-power pumps, portable fridge boxes, heaters, wipers, communication electronics. Often used as a main feeder on 5–7 m boats or for longer wire runs to minimize voltage drop
• 4 mm²: For high current loads – powering heavy-duty bilge pumps, searchlights, audio amplifiers, battery chargers. Recommended for larger boats (~8 m) or devices drawing up to ~25–30 A, where the thicker gauge maintains stable voltage
• 6 mm²: The largest size in this range – used for main battery feeds, battery linking, small windlasses and other heavy consumers (up to ~40 A). Ideal for longer boats 8–10 m where the cable runs are lengthy and require a big gauge to minimize voltage loss

Note: Cables are available in red (positive) and black (negative) insulation. The flexibility of the multi-strand conductor makes it easy to route through tight spaces and allows it to withstand vibration. Whether you’re building a new installation or replacing old wiring, this marine cable provides durability and reliability for your electrical system.
