This Sony Triax Cable is a triaxial type of electrical cable similar to coaxial cable, but with the addition of an extra layer of insulation and a second conducting sheath. It provides greater bandwidth and better rejection of interference than coaxial cable. The 1/2" thickness of this cable allows it to be used over extended distances, up to 3281' (1000 m).

It is most commonly used in the television industry as a connecting cable between a camera and its CCU.
