Description
上記した実施の形態によると、外層200の素線20が内層100の素線10よりも大きい外径を有することにより、雷撃を受けても溶断又は断線することなく優れた耐雷特性を有し、標準AC150mm2と同一の外径で形成されているので、標準AC150mm2に用いる圧縮クランプ、直線スリーブ、ダンパー等の付属品を使用することができる。また、既存の電線製造設備を用いた製造が可能であり、製造、布設に要するコストの増加を生じることがない。
Claims (3)
- 標準架空地線(AC)150mm2 の外径16mmと同一の外径を有し、内層を形成する複数の第1の素線と、前記第1の素線より外径が大で、前記内層の外側に外層を形成する複数の第2の素線とを撚り合わせて形成され、線膨張係数が前記標準架空地線(AC)150mm2 の線膨張係数15.5×10 −6 /℃と同等又は前記標準架空地線(AC)150mm2 の線膨張係数15.5×10 −6 /℃よりも小であることを特徴とする耐雷架空地線。
- 前記第1の素線は、外径が2.53mmから2.80mmで形成され、
前記第2の素線は、外径が3.8mmから4.2mmで形成されることを特徴とする請求項1に記載の耐雷架空地線。 - 前記第1の素線は、導電率が前記第2の素線と同等又は前記第2の素線よりも小であることを特徴とする請求項1又は2に記載の耐雷架空地線。
