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

This marine single-core cable is designed to provide reliable onboard power distribution, even in harsh conditions. The conductor is made of pure multi-stranded copper, ensuring excellent conductivity and flexibility. The extra PVC insulation resists UV rays, saltwater, and mechanical wear, protecting the cable from damage and corrosion. The cable is flame retardant and oil resistant, enhancing safety – crucial for installations in engine bays or confined areas. It’s used for wiring navigation equipment, lighting, pumps, batteries, and other boat systems. Variants are available in different cross-sections (from 1 mm² up to 6 mm²) and color coding for easy identification of positive and negative lines. Recommended uses by cross-section:

• 1 mm²: Suitable for low-current consumers – cabin lights, indicator lamps, sensors (up to ~5–10 A). Typically used on smaller boats or short runs where distances are minimal
• 1.5 mm²: A versatile size for lighting, small bilge or freshwater pumps, horn signals, and other moderate loads (up to ~15 A). A great choice for boats 4–6 m, where most circuits (lights, nav gear) can be powered with this gauge
• 2.5 mm²: For medium loads – ideal for heavier pumps, portable coolers, heaters, wipers, electronics. Often used as main feed lines on small to mid-sized boats (5–7 m) or for longer cable runs to reduce voltage drop
• 4 mm²: Handles high-current devices – powering high-capacity bilge pumps, powerful spotlights, audio amplifiers, chargers. Recommended for larger boats (~8 m) or devices drawing up to ~25–30 A, where the thicker gauge ensures stable voltage
• 6 mm²: The largest size in this range – used for primary power circuits, connecting batteries, small windlasses, and other heavy loads (up to ~40 A). Ideal for longer boats and yachts 8–10 m, where cable runs are long and a large gauge is needed to minimize voltage drop
  Note: The cables are available with red insulation (for positive) and black insulation (for negative/ground), making wiring safer and easier. The flexibility of the multi-stranded copper core aids in routing the cable through tight spaces and allows it to withstand vibrations as the boat moves. Whether you are setting up a new electrical system or replacing an old wire, this marine-certified cable ensures longevity and safety for your boat’s electrical network.
