- Abstract
In this work, in order to solve the problem of longitudinal water resistance for XLPE power cable, nine kinds of corrugated aluminium sheath with different embossing depths and pitchs were pressed by argon arc welding machine. Each sheath was cut into six equal parts to study lateral pressure. After pressure experiment were finished, a group of structural optimization parameters of corrugated aluminium sheath was obtained. The results showed that, maximum value of the yield-point stress was 2.26KN when embossing depth was 24.2mm and pitch was 4.5mm in the longanimous pressure range of the aluminium sheaths. Four kinds of XLPE power cable of length than 3m meeting process requirement were preparated to longitudinal water resistance experiment. The longitudinal water resistance experiment of the corrugated aluminium sheath was made by setting four different clearances or precision cutting widths based on structural optimization parameters in pressure experiment. The experiment results indicated that the shortest water penetration length was 0.31mm when precision cutting width was 244.7mm and clearance was -0.5mm , which achieved excellent effect.
