Accelerated Aging Tests of 69-kV Cross-Linked Polyethylene Cable and Joints

James L. Williams, Aldo Zanona, Alfred R. Lee

Abstract

Test evaluation of 69-kV cross-linked polyethylene (XLPE) cable and joints for use with such cable is described. Joints suitable for connecting together either lengths of 69-kV cross-linked polyethylene (XLPE) cable or XLPE cable to solid-type paper insulated 69-kV cable are studied. It is shown that the characteristics of the tape selected greatly influence the performance of the joint. The thermal resistivity and the thermal expansion of cross-linked polyethylene are also examined.
