本考案の遮水型ケ−ブル用ラミネ−トテ−プは上述した通りの構成であり、第 １金属箔と第２金属箔とを設けて金属箔の全断面積を充分に大にしてあるから、 事故電流に良好に対処でき、外部金属遮蔽層の機能をよく営ましめ得、ケ−ブル コア上への銅テ−プの巻き付けを省略できる。また金属箔の断面積を２層構造に より大きくしているから、曲げ剛性を小さくでき（同一厚さの単一層金属箔の場 合に比べ）、ケ−ブルコアへの縦添えが容易である。 勿論、第１金属箔と第２金属箔との間を導電性または半導電性樹脂によって電 気的に導通してあるから、サ−ジ電圧の到来があっても、両金属箔間での電気ス トレスの作用を排除でき、安全である。 The laminated tape for waterproof cables of the present invention has the structure as described above. Since the first metal foil and the second metal foil are provided to make the total cross-sectional area of the metal foil sufficiently large, It can cope well with fault currents, and the function of the external metal shielding layer can be well maintained. Wrapping of copper tape on the core can be omitted. In addition, the cross-sectional area of the metal foil has been changed to a two-layer structure. Because it is larger, the bending rigidity can be reduced (in the case of a single layer metal foil of the same thickness) (compared to other cables), it is easier to attach the cable vertically to the cable core. Of course, electricity is connected between the first metal foil and the second metal foil using a conductive or semiconductive resin. Because they are electrically conductive, even if a surge voltage arrives, there will be no electrical current between the two metal foils. It is safe because the effect of stress can be eliminated.
