Abstract

The evaluation of large quantities of field aged high molecular weight polyethylene (HMWPE) cables which were subjected to extensive electrical and physical testing is described. The electrical tests conducted were AC and DC breakdowns, corona extinction, and volume resistivity. The physical tests included semiconducting shield adhesion. Microscopic studies were conductor for semiconducting shield protrusions, void and contamination count, and treeing. The results of the electrical and physical testing are reported. The correlation between AC breakdown strength and treeing is presented
