Inner dielectric insulator. D. Copper core. Coax. Cable. Coaxial cable, or coax is a type of cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Coaxial cable differs from other shielded cable used for carrying lower-frequency signals, such as audio signals in that the dimensions of the cable are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a radio frequency transmission line.. by Mike Denko, Alex Motalleb, and Tony Qian .
