Coaxial cable and method for forming the cable
A cable may include an inner conductor and an outer conductor coaxially arranged around the inner conductor. A dielectric strength member may be positioned between the inner and outer conductors. The dielectric strength member may have a thickness between 0.1 mm and 50 mm and a tensile strength of at least 5,000 MPa. Additionally, a jacket may be formed around the outer conductor.
