COAXIAL CABLE INCLUDING TUBULAR BIMETALLIC OUTER LAYER WITH BEVELLED EDGE JOINT AND ASSOCIATED METHODS
First Claim
1. A coaxial cable comprising:
- an inner conductor, an outer conductor and a dielectric material layer therebetween;
said outer conductor comprising a tubular bimetallic layer having a pair of opposing longitudinal edges at a longitudinal seam;
said tubular bimetallic layer comprising an inner metal layer and an outer metal layer bonded thereto with said outer metal layer having a lower melting temperature than said inner metal layer;
at least one of said opposing longitudinal edges of said tubular bimetallic layer being at least partially bevelled;
the longitudinal seam comprising a welded joint between at least portions of said opposing longitudinal edges.

Abstract
A coaxial cable may include an inner conductor, an outer conductor, and a dielectric material layer therebetween. The outer conductor may include a tubular bimetallic layer having a pair of opposing longitudinal edges at a longitudinal seam. The tubular bimetallic layer may include an inner metal layer and an outer metal layer bonded thereto with the outer metal layer having a lower melting point than the inner layer. At least one of the opposing longitudinal edges of the tubular bimetallic layer may be at least partially bevelled. In addition, the longitudinal seam may include a welded joint between at least portions of the opposing longitudinal edges.
