Application dynamics of high temperature conductors in full tension splices & deadends

This paper addresses the electrical and mechanical properties and electrical performance characteristics of full tension deadend and splice connectors for use on high temperature conductors, principally those used in overhead transmission and distribution. While concentrated efforts on conductor design, incorporating the use of composite cores of various materials are on the brink of introduction at the date of this writing, the successful leader in this field to date is ACSS (aluminum conductor - steel supported) cable. Proposed continuous operating temperatures listed for this conductor of 250°C (482°F), present a variety of technical issues for splicing, and full tension deadend applications of conductors operating at these temperatures, which are addressed.
