Each conductor is made from \u003cstrong\u003e96 strands of 0.32mm tinned copper wire\u003c\/strong\u003e, providing excellent flexibility and superior corrosion resistance compared to bare copper. The tinning protects against saltwater, moisture, and humidity, reducing the risk of premature failure in bilge areas, engine rooms, and exposed deck runs.\u003c\/p\u003e\n\u003cp\u003eSupplied on a convenient \u003cstrong\u003e30 metre roll\u003c\/strong\u003e, this cable is ideal for wiring battery banks, winches, solar regulators, and high-current DC circuits on yachts, powerboats, and commercial vessels. The twin core configuration (red and black) simplifies installation and polarity identification, while the robust double-insulated construction meets the requirements of \u003cstrong\u003eAS\/NZS 3808\u003c\/strong\u003e for safety and performance.\u003c\/p\u003e\n\u003ch3\u003eWhy Tinned Copper Matters\u003c\/h3\u003e\n\u003cp\u003eStandard automotive or building wire uses bare copper, which oxidises rapidly in moist, salty air.
