Tinned Instrumentation Copper Cable

Whilst copper does have some element of resistance to corrosion, there are some environments where it is not recommended to use bare copper. Environments that are wet or have high humidity can often cause copper to corrode relatively quickly. For example, with solar cabling where copper can often be exposed to the elements, or marine cabling (where the possibility of water damage is obvious), may require some form of

In many instances the remedy for such problems is for some coating to be applied to the bare copper conductor. The coating of copper conductors is usually done to reduce oxidation or corrosion, or to improve electrical properties at high frequencies. Coating has also been used to make stripping the cable easier in some cases.

Tin is the most common coating material, which explains the term ‘tinned’ copper. Tin’s main use in practice is to prevent oxidation. When copper is oxidised, it turns green. The main problem with this is that it reduces the effectiveness of the copper conductor, due to the fact that the green copper oxide is a semiconductor.

To prevent oxidation, something must be put over the copper conductor, with a layer of tin being the most common method. The thickness of the coating over the conductor typically depends up on the coating material used and the specific cable involved. Tinned copper cable is usually only effective up to temperatures of 150°C. Alternatives to tin do exist, and are usually used at the temperatures that render tin ineffective. Silver and nickel are the most common alternatives to tin. Silver’s conductive properties are actually greater than copper, but there are obvious economic reasons that preclude silver-based cables from most of the market. On e interesting fact is that when silver oxidises, silver oxide has exactly the same conductive properties as normal silver. Nickel can also be used, although it is a relatively poor conductor. This means that nickel’s main use as a conductor coating is at high temperature, as it outperforms tin from 250°C to 450°C.

Generally speaking, should conductor coating be necessary, the only logical choice for most applications is tinned copper cable, except in a few specialist environments. However, there are some that would argue that tinning is no longer necessary for most cables in this day and age, due to advances in tape, screening, braid and insulation.
