Abstract
A transmission cable includes a conductor and a composite layer. The composite layer is formed by having an inner surface of an outer wrap layer adhered to an outer surface of an inner wrap layer with a glue material. The composite layer wraps the conductor and an inner surface of the inner wrap layer is in contact with an outer surface of the conductor. The inner wrap layer is made of polytetrafluoroethylene with a foaming degree of 65% to 77%, and the outer wrap layer is made of polyimide. The composite layer is made by drawing cable at a rate of 0.1-0.5 m/min and taping with an overlap percentage between 32% and 37% during a wrapping process.
