Electrical cable Etymology

2023-11-03

The original meaning of cable in the electrical wiring sense was for submarine telegraph cables that were armoured with iron or steel wires. Early attempts to lay submarine cables without armouring failed because they were too easily damaged. The armouring in these early days (mid-19th century) was implemented in separate factories to the factories making the cable cores. These companies were specialists in manufacturing wire rope of the kind used for nautical cables. Hence, the finished armoured cores were also called cables. The term was later extended to any bundle of electrical conductors (or even a single conductor) enclosed in an outer sheath, whether or not it was armoured. The term is now also applied to telecommunications cables with fibre-optic cores within the outer sheath rather than copper conductors.
