ABSTRACT:
A dielectric system for coaxial electrical conductors is provided. The dielectric system separates an inner and an outer conductor and is composed of a first layer of cellular polyparabanic acid. This layer directly contacts and provides a continuous skin circumferentially surrounding the inner conductor along its length. A second layer, consisting of a crosslinkable polymeric lacquer which provides a continuous skin enclosing the first layer is also provided. The dielectric system is used in coax cables.
