Laboratory Evaluation of 345-kY Cable 4 Low-Pressure Oil-Filled Self-Contained Type After Field Testing at Cornell University

Upon completion of the 345-kV cable field testing at Cornell University, the cable and accessories employed in the low-pressure oil-filled cable system were returned to the cable manufacturers´ laboratories for analysis. This paper describes the various electrical, chemical, and physical tests performed on components of the low-pressure oil-filled system. Where practicable, the post-Cornell results are compared with pre-Cornell data.
