Abstract
A rubber or plastic insulated power cable is provided wherein a water impervious tape is formed on a cable core through an electrically conductive tape. Fracture due to fatigue of the metal foil of the water impervious tape which is caused by friction between a metal shield layer of the cable core and a jacket as an outermost layer is prevented. Water impervious performance of the cable is not degraded over a long period of time.
