## Description

Product description Standard USA Marine Wire We have customized a PVC jacket to prevent seawater corrosion, effectively extending the service life of the wire Wires with more than 98% copper content, standard OFC marine wires. Specification Tinned copper Kimbluth uses the highest technology tinned copper to produce wires. Tinned copper is mainly used to prevent OFC from oxidizing, effectively improving conductivity and extending the service life of the wire. So it is very suitable for outdoor, communication and ships Widely used wires In addition to anti-corrosion, our wires are also flexible to prevent hardening of the jacket due to UV, so it can be used in extreme marine environments.

Review: Quality Salt Water Corrosion Resistance Upgrade for Trolling Motor - Replaced 20 year old smaller gauge wiring for remote trolling motor and lithium battery. This is tinned for minimizing salt water corrosion and I reduced battery to trolling motor length reducing overall in line resistance and heat build up. This product is very high quality tinned copper enclosed in vinyl reducing concern for rubbing and wear of boat pounding waves etc. It was extra easy to route as one piece versus two single wires one hot and one negative. I'm super satisfied with its ease of installation and superior quality. I can already see the improvement in power to the trolling motor. I installed an inline circuit breaker with shutoff and new battery mount I should have done years ago. Great product that's hard to find an purchased all available at a good price on desertcart
Review: Excellent all copper - I had copper clad aluminum and that was no working to power the power lift in back of my van to lift my power chair. The circuitry kept cutting out as the wattage was not coming through or the voltage dropped and the amps went up. This OFC pure copper wire works great. I didn't test the amperage being pulled but it must be lot less and the volts must be more with the less resistance as the lift goes up faster that ever and doesn't cut out. I also appreciate the thick protective coating as wire is tie wrapped along the C channel frame om my E150 van. What really impressed me was how easy the protective coating released from the conductors; not like the underground burial USB wire. The multi'strand 8 gauge wire was also very workable and flexed where i needed it to go.
