Evaluation of 230 kV HPFF pipe-type cable with wrinkled and creased insulating tapes

Severe collapse wrinkles and circumferential creases were discovered in the cellulose paper insulating tapes of a newly installed HPFF pipe-type cable during splicing and terminating. An evaluation program was developed to assess the electrical and mechanical integrity of the cable having wrinkled and creased insulating tapes. The test results indicated that the cable would perform satisfactorily in service. >
