Ribbon type cables are now available insulated with strain-free PTFE. These cables are produced with essentially any size or type of conductor and almost any combination of leads e.g. mixed sizes, thickness of insulation, coax, twisted pairs, shielded and unshielded, etc. can be supplied in the same ribbon cable. These cables remain tough and flexible at extremely low temperatures, and with suitable conductors they can be used continuously at above 300C. Spacing of the conductors can be manipulated to give required electrical characteristics. The order sequence of leads across the ribbon offers a new dimension in lead identification that greatly increases the identification capacity of these cables. Important savings in space and weight are possible with these new ribbon cables. Author
