A highly flexible electrical conductor, it is characterized by numerous, very fine strands of conductive material, often copper or a copper alloy, wrapped around a non-conductive core, typically made of textile yarn or synthetic fiber. This construction imparts exceptional pliability, enabling it to withstand repeated bending and flexing without fracturing. An example of its application is found in headphone cables and other frequently manipulated cords where durability is paramount.
Its significance lies in its ability to maintain electrical continuity even under severe mechanical stress. This makes it invaluable in applications where standard wire would quickly fail due to fatigue. Historically, the development of this type of conductor was driven by the need for robust connections in telephone switchboards and early electrical appliances that were subject to constant movement and handling.
