The growing utilization of high voltage cable with extruded insulation predicts the need to connect this type of cable with cables having different insulations. This paper describes the successful development of a 138 kV transition joint between high-pressure dielectric-fluid filled cable with paper insulation to cable with extruded insulation, such as cross-linked polyethylene or ethylene propylene rubber. Such a joint must have adequate electrical and mechanical properties and contain the high-pressure dielectric fluid normally at 1400 kPa (200 lb/in[sup 2]). There is an anticipated need for such a transition joint on the Con Edison system.
