Coaxial cables have one conductor insulated with a dielectric material and then surrounded by the other conductor, usually referred to as the center conductor and shield. Triaxial cables are specialized coaxial cables.
Electrical connectors are devices that join electrical circuits together. Male connectors plug into receptacles, jacks, and outlets. Female connectors contain sockets to receive other devices.
Power cables are solid or stranded conductors surrounded by insulation, shielding, and a protective jacket. These cables are designed for high voltages (>600 V).
