It is understood that this is because the electric resistance of the water-absorbing tape 2 is larger than that of the outer semiconductive layer 1d constituting the outermost layer of the cable core 1. That is, the volume specific resistance of the water absorbing tape 2 is 1
About 10 5 to 1 × 10 6 Ω · cm, whereas the volume resistivity of the outer semiconductive layer 1 d of the cable core 1 is 1 × 1
Therefore, the charging current of the cable flows through the outer semiconductive layer 1d having a small electric resistance along the longitudinal direction as shown by the arrow in FIG.
It can be understood that the charging current concentrated below the valley 3a flows through the water-absorbing tape 2 having high electric resistance in the thickness direction.
