On-core water impervious cable has a water impervious layer consisting of lead foil and semiconductive plastic film, which is thermally bonded to the insulation shield of the cable core and prevents ingress of water to the interior of the cable core. According to this design, the water impervious layer is subjected to thermal expansion and contraction directly from the core and thermal fatigue properties assume greater importance. Strain in the water impervious layer, aging property in lead foil, heat cycle property on the cable, and high temperature fatigue property on composite tape were investigated. Based on these results, the authors have estimated the life of the on-core water impervious layer and confirmed a level of aging life of approximately 40 years.
