    摘要： A self-damping electrical conductor for suspension between spaced supports, the conductor including a hollow conductive mantle and a conductive core loosely disposed therein. The conductive core comprises at least two substantially straight conductors extending through the mantle in essentially parallel relationship to the longitudinal axis thereof, and loosely disposed with respect to each other and to the mantle. The conductive mantle and the core conductors have several different combinations of stress-strain characteristics, density, and coefficient of thermal expansion, such that the core conductors inherently seek different sags when the mantle and core are suspended under tension between supports.
