Electrical cables are essential components used to transmit electrical power or signals from one location to another. These cables are made up of multiple conductors, usually copper or aluminum, which are insulated and bound together in a protective sheath. The insulation material, often PVC, rubber, or polyethylene, prevents short circuits and ensures safety.

Electrical cables come in various types and sizes to suit different applications, including power distribution, telecommunications, and data transmission. Power cables, for example, are designed to carry high voltage and current, whereas data cables are optimized for transmitting digital signals with minimal interference. Shielded cables are used in environments with high electromagnetic interference to ensure signal integrity.

Key specifications of electrical cables include voltage rating, current capacity, insulation type, and temperature rating. Proper selection of cables is crucial for efficiency and safety in electrical systems, ensuring reliable performance and minimizing risks of overheating or electrical fires. Electrical cables are integral to modern infrastructure, from residential wiring to industrial power networks.
