Abstract

Theoretical and experimental work was done to find a way to prevent cable movement in underground cable splices, and an attempt was made to cope with the phenomenon known as creepage. By anchoring the cable to the splice, residual pulling tension, thermal stress, and creepage was counteracted. To prevent cable movement the cable was reinforced with stainless steel tension members that keep the cable in position by a spring action. Cable creepage is analyzed, and the cable and splice design is described. Following satisfactory demonstration in field tests, a 275 kV high-pressure fluid-filled (HPFF) cable incorporating the new splices was used in a newly installed HPFF cable line. >
