Abstract

Commercially available coaxial cables have been used successfully in single shot electromagnetic launcher and other pulsed power applications. The use of a coaxial cable interface between power source and pulsed power load reduces external magnetic fields and also aids in standardizing the interface, enhancing inter-changeability between a variety of power supplies and loads. As pulsed power systems continue to become more energetic and as the importance of repetitive operation increases, the use of commercially available cables becomes impractical because of the large number required for appropriate energy transfer. The cable according to the invention overcomes many problems encountered in the use of conventional cables. It incorporates a large area, flexible conductor in both the current feed and current return path, and matches these conductor cross-sections to provide uniform current paths. It also incorporates high temperature PFA TEFLON insulation capable of operating at 260 degrees C, and uses a high strength woven fiber cover to resist intense forces produced by internal currents and magnetic fields. A standardized, uniform dimension, nonarcing interface termination is also provided. The combination of components and materials easily allows this cable to be used to replace more than six conventional cables.
