Abstract

A coaxial cable includes a center conductor, and an insulation formed surrounding the center conductor. The insulation includes an insulating tape that includes a mesh layer including a plurality of threads woven and a reinforcement layer attached to the mesh layer. The insulating tape is wound, with an overlap, around the center conductor such that the mesh layer is arranged as an outer peripheral surface.

Claims

1. A coaxial cable, comprising:

a center conductor; and

an insulation formed surrounding the center conductor,

wherein the insulation comprises an insulating tape that comprises a mesh layer comprising a plurality of threads woven and a reinforcement layer attached to the mesh layer, and,

wherein the insulating tape is wound, with an overlap, around the center conductor such that the reinforcement layer contacts the center conductor and the mesh layer does not contact the center conductor and is arranged as an outer peripheral surface.

2. The coaxial cable according to claim 1, wherein the threads comprise a polytetrafluoroethylene or polyethylene, and wherein the reinforcement layer comprises a polyethylene terephthalate.

3. The coaxial cable according to claim 1, further comprising a protector formed surrounding the insulation.

4. The coaxial cable according to claim 3, wherein the protector comprises a protective tape wound around the insulation or a protective layer molded around the insulation by non-filled extrusion.

5. The coaxial cable according to claim 1, wherein the insulating tape is not more than 30 μ

m in thickness.

6. A medical cable, comprising a plurality of core wire units, wherein the plurality of core wire units each comprise a plurality of ones of coaxial cable according to claim 1 that are twisted together.

7. The coaxial cable according to claim 1, wherein neither the reinforcement layer or the mesh layer are formed from a foamed resin.
