What is the difference between a wire and a cable?

Although the terms "wire" and "cable" are often used interchangeably, they refer to different electrical products.

A wire is a single electrical conductor, typically made of copper or aluminum, used to carry electrical current from one point to another. It may consist of a solid conductor or multiple strands twisted together and is usually covered with a layer of insulation for protection.

A cable, on the other hand, consists of two or more insulated conductors bundled together and enclosed within an additional protective sheath. Depending on its application, a cable may also include shielding, armoring, and other protective layers to enhance durability and performance.

In terms of application, wires are commonly used for internal wiring in electrical equipment, residential installations, and simple electrical circuits. Cables are designed for more demanding applications such as power transmission, industrial systems, telecommunications, data transmission, and large-scale infrastructure projects.

Cables generally offer greater protection against moisture, heat, mechanical damage, and environmental conditions due to their multi-layer construction. This makes them more suitable for harsh operating environments and long-distance transmission.

In simple terms, a wire is a single conductor that carries electricity, while a cable is a collection of multiple conductors packaged together with additional protective layers for enhanced safety, durability, and performance. While every cable contains wires, not every wire is a cable.
