When it comes to cable there are two main varieties. These are solid-core, also known as single stranded wire, or stranded wire. Both are able to be used as a conductor, but some offer different benefits depending on the application it will be used for. Working closely with trusted suppliers is the best way to make sure that you end up with the finished product you need.
While solid wire is a cheaper version and can be perfect in numerous settings, it can mainly only be used in situations where flexibility is not needed. It can provide ruggedness and it can help protect corrosives from being exposed. The big advantage stranded cable is able to supply is flexibility. It is able to withstand a great deal of stress in some highly technical work environments. It can also reduce levels of the skin effect, in which the current will transfer more towards the surface of the wire. They are the perfect solution for industries that require large amounts of lifting, support and tension.
Stranded wire can be broken down even further depending on how many strands it actually contains. The wires are typically enclosed in a protective casing, often made of a type of plastic. This helps to keep them all together and tightly bound. The lowest number typically found is seven, this means six wires wrapped around the one central wire. From there popular combinations include 19, 37 and 49, but it can go up to the 100 range. Once the number has approached 19 it can be safely used in situations that will require movement. In the end, it is the application that will determine which model will be of the best use. While stranded cable is able to offer more in most cases, the solid cable will be cheaper, and if will serve the purpose will probably be the better choice.
