Difference between wire and cables

WIRE:-A wire is a single strand or a group of strands of an electrically conductive material, usually aluminium or copper. A cable consists of two or more insulated conductors and can be either bare or covered. The easiest way to distinguish between the two is that the wire is usually visible, whereas a cable is most usually insulated.

There are two main types of wires-solid or stranded. A solid wire is usually a long length of single conductor. A stranded wire is many thin strands of wires twisted together. Solid wires offer low resistance and are perfect for use in higher frequencies, whereas a stranded wire has a longer life, due to its flexibility and can be used for a longer period than a single conductor.


Wires are mainly used to carry electrical and telecommunications signals, but can also be used in various other forms, from bearing mechanical loads, to heating, to even in jewellery and clothing.

CABLES -A cable is usually two or more wires running together or bonded, twisted or braided together. They are usually insulated rather than not, which gives them a better protection than just wires. Cables are mainly used to carry electrical and telecommunications signals.

There are various types of cables, including twisted pair cable, coaxial cable, multi conductor cable and fiber optic cable.

  • A twisted pair cable has two cables twisted around each other and is mainly used to carrying signals.
  • A multi conductor cable is made up of many conductors insulated from each other, and is best suited for control.
  • In a coaxial cable, the signal on the two conductors is not same. This is called an unbalanced line and performance on this cable is more stable than on a twisted pair cable.
