High energy coaxial cable for use in pulsed high energy systems

A high energy coaxial cable for use in pulsed high energy systems, comprising:

• a center conductor comprised of fine nickel plated copper strands, wherein a core portion of the strands are counter-wound from the outer strands for improved flexibility;
• an outer conductor comprised of two counter-wound layers of stranded nickel plated fine copper wire, the cross-sectional area of the outer conductor being slightly greater than that of the inner conductor in order to completely fill the conductor region and prevent voids which would allow pinching force damage;
• an inner dielectric between the center and outer conductors, the dielectric being of extruded perfluoroalkoxy (PFA);
• an outer dielectric over the outer conductor for holding the outer conductor in place, the dielectric being extruded perfluoroalkoxy (PFA), whereby the operational temperatures of the conductors may exceed 260.degree. C.;
• a reinforcing mesh woven as a braid over the outer dielectric for aiding in the containment of magnetic burst forces, the mesh being manufactured from an aramid fiber, with braid angles kept high for maximizing strength in the radial direction and maintaining tightness during manufacture;
• an outer jacket made of a flame retardent polyether based polyurethane.
