Wire and Cable: An OverviewWire and cable are essential components in electrical and communication systems, used to transmit electricity, signals, or data. Wire typically refers to a single conductor (often made of copper or aluminum) that carries electrical current, while cable is a collection of wires bundled together, often insulated and protected by an outer sheath for safety and durability. They come in various specifications—such as different cross-sectional areas (measured in square millimeters) and insulation materials—to suit diverse applications: from household wiring (small-gauge wires) to industrial power transmission (large-capacity cables). Common types include power cables (for electrical distribution), communication cables (for data/voice transfer), and control cables (for operating equipment).
