Laboratory Evaluation of 345-kY Cable 3 High-Pressure Oil-Filled Self-Contained Type After Field Testing at Cornell University

As the final phase of the Cornell cable system development program [1], a comprehensive laboratory evaluation of aged cable and accessory components was carried out in the manufacturers´ laboratories. Electrical, physical, and chemical tests on aged components provide a basis for comparison with characteristic data, when new. Results demonstrate essentially that complete system stability was maintained throughout the field test program. In addition, the results of a load cycle test run at greatly reduced pressures on the self-contained high-pressure oil-filled cable, conducted in the manufacturers´ laboratory, are described.
