Abstract
The invention relates to a coaxial cable (10) comprising a central inner conductor (11) that is concentrically surrounded by an outer conductor (12) at a specified distance, wherein the intermediate space between the inner conductor (11) and outer conductor (12) is filled with a dielectric (13). A coaxial cable having especially good mechanical and electrical properties is achieved by the dielectric (13) comprising a plurality of hollow fibers (14, 15, 19) that extend in the longitudinal direction of the cable and are composed of a glass, and by at least the inner conductor (11) having a thermal expansion coefficient that is matched to the dielectric (13) with regard to a least possible temperature-related phase change in the coaxial cable (10).
Claims15
A coaxial cable (10, 20) comprising:
- a central inner conductor (11) concentrically surrounded by an outer conductor (12) at a specified distance, an intermediate space between the inner conductor (11) and the outer conductor (12) filled with a dielectric (13), wherein the dielectric (13) is made up of a plurality of hollow fibers (14, 15, 19) comprising a glass and extending in a longitudinal direction of the cable, and in that at least the inner conductor (11) has a coefficient of thermal expansion which is made to match the dielectric (13) with regard to a temperature-related phase change in the coaxial cable (10, 20) that is as small as possible.
