A shielding copper tape 3a (or copper wire) is wound around the outer side of 2' with an external semiconductive layer interposed therebetween, and a holding tape 3b is further wound thereon to form a shielding layer 3. Next, a laminate tape made by laminating a semiconductive sheet 4b such as a semiconductive polyethylene or polyvinyl chloride sheet on one or both sides of a metal foil 4a made of lead, copper, aluminum, etc. is then placed on top of it and wrapped around it. Then, a water-blocking layer 4 is provided, and finally a sheath 5 is applied to the outside of this layer.

がある。 However, if there is a lightning strike near the cable connection, the potential between the shielding layer 3 and the water shielding layer 4 will rise rapidly, and the potential on the grounded shielding layer 3 will quickly drop to zero, but the potential on the grounded shielding layer 3 will quickly drop to zero. The potential of the water-shielding layer 4 does not immediately become zero potential, but remains in a charged state, and depending on the potential difference, a discharge occurs between the water-shielding layer 4 and the copper tape 3a of the shielding layer 3. There is a risk that the metal foil 4a of the water-blocking layer 4 will melt due to the heat generated at this time, creating holes, and the water-blocking effect will be impaired. In addition, if the terminal or intermediate connection of the water-shielded power cable 1 is performed under high potential conditions, the human body may be struck by lightning.
There are problems such as the work being dangerous. For these reasons, it is necessary to ground this water-blocking layer as well.
