Abstract
A cable for high frequency use in an environment with high and varying thermal changes whereby the thermal expansion of the cable is controlled by having a highly electrically conductive metal bonded to a metal of low coefficient of thermal expansion relative to the high electrically conductive metal. This is accomplished by providing a thin layer of highly electrically conductive metal over an inner core of a metal of low coefficient of thermal expansion. The cable can also utilize a similar bonded metal configuration for an outer concentric conductive sheath having a mineral dielectric between conductors that also has a low coefficient of thermal expansion.
