National Wire & Cable Corporation Datasheets for Coaxial Cables and Triaxial Cables

Coaxial cables have an inner conductor insulated by a dielectric material and then surrounded by an outer conductor that is shielded with braid or foil. Triaxial cables add an extra layer of insulation and a second conductive sheath. They are commonly known as coax and triax, and are chosen because of their protection against external electromagnetic interference.
