Abstract

The transmission line for wired pipe applications includes an inner conductor, an insulating material surrounding the inner conductor, the insulating material having an initial outer diameter, and a wire channel surrounding the insulating material and the inner conductor for at least a portion of a length of the transmission line. The wire channel is formed from at least two profiles forced together to compress the insulating material such that it has a final outer diameter that is less than the initial outer diameter.
