Wires are conductors used to transmit electrical power or telecommunications signals. They can be classified into single-strand and multiple-strand wires, typically made from metals such as copper or aluminum, and are insulated with a layer of material to ensure that electrical current does not leak or cause short circuits during transmission. Cables, on the other hand, are components used to connect two devices to transmit electrical signals. They consist of two or more conductors bonded, twisted, or braided together. Cables have a wide range of applications, each requiring customization, and their main functions include transmitting electrical power, electrical signals, and enabling electromagnetic energy conversion.
