1.Cable Structure
Building wire and cable carry electrical current from a power source to a device in a building, such as an outlet or light fixture. Building wire is typically run through conduit, cable trays, or raceways. Building cable consists of multiple strands of wire bundled inside a thermoplastic or metal sheath. Building wire and cable are typically used to run new circuits or extend old circuits inside walls and ceilings in commercial, industrial, and residential properties.
2.Application
While the terms wire and cable are often used interchangeably, wire is one electrical conductor and cable is a group of wires (or conductors) encased in sheathing.
Building wire and cable is used in the construction of almost every commercial, industrial, and residential property in the world. Most commonly known as branch circuit wiring in homes and businesses, these products carry electrical current to all power applications in a building or dwelling.
