ANCOR Marine Grade wire is manufactured from tinned copper stranding for maximum protection against corrosion and electrolysis. Ultra flexible (Type 3) stranding resists fatigue due to vibration and flexing. ANCOR proprietary premium vinyl insulation stays flexible even in extreme cold and resists salt water, battery acid, oil, gasoline and ultra-violet radiation. Exclusive insulation is rated at 600 volts, 105 degree C dry and 75 degree C wet, and is resistant too! Exceeds all UL 1426, US Coast Guard Charterboat (CFR Title 46) and ABYC standards. ANCOR supplies a full line of Marine Grade primary (single conductor) wire in sizes from 18 AWG to 10 AWG, all in ABYC recommended colors, and in standard lengths from 8 foot mini-spools to 1,000 foot bulk spools.
