  • Method for making low noise signal transmission cable
    Patent number: 5554236
    Abstract: An improved low noise electrical signal transmission cable is disclosed. The cable employs an insulative layer of expanded polytetrafluoroethylene (PTFE) which is bonded in fixed relative position with a surrounding shield layer through use of an adhesive, such as fluorinated ethylenepropylene (FEP) or perfluoroalkoxy polymer (PFA). The bonding process reduces the separation of layers which can sometimes occur with expanded PTFE insulative cables and avoids the generation of unwanted triboelectric signals that can result from such separation.
