Electrical cables are essential components used to transmit electricity from one point to another. They consist of one or more conductors, usually made of copper or aluminum, which are insulated to prevent electrical shocks and short circuits. These cables come in various sizes and types, designed for different applications, such as powering homes, offices, and industrial equipment. The insulation around the conductors is crucial for safety, as it protects against moisture and physical damage. Common types of electrical cables include power cables, data cables, and fiber optic cables, each serving specific purposes in our daily lives, from lighting our homes to enabling high-speed internet connections.
