Abstract
In a coaxial electrical high-frequency cable, a spacer is provided between the internal conductor and the external conductor in order to maintain the operation of the cable even in the case of elevated ambient temperatures. The spacer can be a helical profile or of individual shaped pieces made of glass or ceramic materials.
Claims21
A coaxial electrical high-frequency cable comprising:
- an internal conductor;
- an external conductor;
- and
- spacing means having a helical profile and being made predominantly of dielectric materials, wherein areas between the internal and external conductors free of the spacing means are at least partially filled with an insulating material, the insulating material is covered by a refractory material.
A coaxial electrical high-frequency cable comprising:
- an internal conductor;
- an external conductor;
- and
- spacing means having a helical profile and being made predominantly of dielectric materials, wherein the helical profile includes a plurality of profile bodies, around which glass or ceramic fibers are braided or spun.
A coaxial electrical high-frequency cable comprising:
- an internal conductor;
- an external conductor;
- and
- spacing means having a helical profile and being made predominantly of dielectric materials, wherein the spacing means is surrounded by a plastic tube which is covered on its outer portion by a refractory material.
