Joints and terminations for pipe-type cable insulated with paper-polypropylene-paper tapes: Final report
Technical Report
·
OSTI ID:6825744
This work developed optimized joint and terminal options for 138--550 kV paper-polypropylene-paper (PPP) cables using conventional materials. In the process, the state of the art of conventional jointing and terminating techniques worldwide was examined and a design process formulated and presented. Test data available on hand-taped joints suggested a maximum radial design stress level of 1750 V/mil at impulse for hand-taped PPP splices. Additional testing is recommended to confirm the maximum axial stress level, but available data indicate that levels much greater than present US practice are acceptable. 86 refs., 78 figs., 16 tabs.
