Cable

Definition

A cable is a thin, flexible line designed to carry tensile forces. It can also refer to a bundle of two or more electrical conductors used to transmit electrical power or signals.

Purpose

Cables serve various purposes in mechanical and electrical systems. In mechanical applications, they are used to support structures and transmit forces. In electrical systems, cables transmit power and signals between devices, ensuring connectivity and functionality.

Examples of Use

1. Structural Support: Suspension bridges use cables to support the bridge deck.
2. Electrical Transmission: Power cables transmit electricity from power plants to homes and businesses.
3. Communication: Coaxial cables transmit television and internet signals.

Related Terms

• Wire: A single, usually cylindrical, flexible strand or rod of metal.
• Conductor: A material or object that permits the flow of electrical current.
• Insulation: Material used to isolate electrical conductors to prevent unintended current flow.

Notes

Cables come in various types and sizes, each suited for specific applications. The selection of the appropriate cable involves considering factors such as tensile strength, electrical capacity, environmental conditions, and compliance with safety standards.
