Multi-core cable is an electrical cable that contains multiple conductors, or wires, within a single outer sheath. This design allows for the transmission of multiple signals or power sources simultaneously, making it efficient for various applications. Commonly used in telecommunications and data transmission, multi-core cables can support complex systems with minimal space requirements. These cables are often found in computers, audio equipment, and industrial machinery. The individual cores can be insulated separately, which helps reduce interference and enhances performance. Multi-core cables are essential for modern technology, enabling reliable connections in a compact format.
