1.5mm² high temperature thin wall marine grade cable with tinned copper conductors, particularly suitable for marine and other harsh environments where plain copper conductors can corrode.

This cable is the same specification as our plain copper thin wall cable, except that the copper conductors have been coated with tin to prevent corrosion. Thin Wall insulation provides significant weight and volume savings, particularly in large wiring harnesses, and the hard grade insulation provides good protection against abrasion damage and cut-through. It has good resistance to fuels (petrol & diesel), oils and dilute acids and a very high resistance to moisture.

Tinned cable
Sunday, 3 December 2017  |  Dylan

The cable is excellent. I am re- wiring a boat and found that the cable is flexible, outer plastic is easily removed, and the wire strands cut well. I like that the cable has the specification on the outer sheath.

I'm currently rewiring my boat so tinned wire was a must. Really good quality stuff that will last for years.

My first choice of cable

This is for marine use so I chose tinned. Good quality and easy to install. I used this cable on the original installation and no sign of corrosion.

It is what is says on the tin. Ordering was easy and delivery was prompt. I would recommend 12v Planet to anyone with a boat or caravan that struggles to find the bits you need elsewhere.
