This paper describes the design, development and laboratory testing of a high voltage PPP (paper polypropylene/paper laminate) insulated joint for commercial application on 138-kV PPP-insulated cable. The design approach taken is conservative and addresses the typical variations in field conditions and in skill and workmanship of the splicing. Joint construction details, including choice of connector, taping structure, and joint mechanical reinforcement, are discussed. The test criteria are described and results are presented.
