Coaxial cable is a type of copper cable specially built with a metal shield and other components engineered to block signal interference.
A coaxial — or coax — cable is primarily used by cable TV companies to connect their satellite antenna facilities to customer homes and businesses. Telephone companies also sometimes use coax cable to connect central offices to telephone poles near customers.
A coaxial cable is an electrical cable with a copper conductor and an insulator shielding around it and a braided metal mesh that prevents signal interference and cross talk. Coaxial cable is also known as coax.
The core copper conductor is used for the transmission of signals and the insulator is used to provide insulation to the copper conductor and the insulator is surrounded by a braided metal conductor which helps to prevent the interference of electrical signals and prevent cross talk. This entire setup is again covered with a protective plastic layer to provide extra safety to the cable.
