Electrical cables are essential components used to transmit electricity from one place to another. They consist of one or more conductors, usually made of copper or aluminum, which carry the electrical current. These conductors are often insulated with materials like plastic or rubber to prevent short circuits and protect against environmental factors. Cables come in various types and sizes, depending on their intended use. For example, power cables are used for high-voltage applications, while data cables are designed for transmitting information between devices. Understanding the different types of electrical cables helps ensure safe and efficient electrical installations.
