Ancor's Safety Duplex Cable features red and yellow Marine Grade primary conductors (correctly color-coded to ABYC standards) in a white common jacket that is made for easy removal while providing the best abrasion resistance available. These cables exceed UL 1426 standards and are made from the highest quality ultra-flexible (Type 3/Class K) tinned copper stranding that provides maximum protection against corrosion and electrolysis while resisting fatigue due to vibration and flexing. The premium vinyl insulation is rated at 600 volts, 105 degrees C dry and 75 degrees C wet, stays flexible even in extreme cold (-40 degrees F/C) and resists salt water, battery acid, oil, gasoline, heat, abrasion and ultra-violet radiation.
