Abstract
Description
前記鋼線1の引張強度の範囲を200kgf/mm2以上に限定する理由は、200kgf/mm2未満では、アルミニウムの線熱膨張係数よりも低い線熱膨張係数を有する鋼線の張力分担率が低くなり、結果として、架空絶縁電線の150℃でのサグが増加することにより、既存の電柱を利用しにくくなるためである。
前記導体層の素線として軟化熱処理されたアルミニウム線の引張強度の範囲を限定する理由は、7kgf/mm2未満では、撚線(stranding)時に頻繁な断線の恐れがあるためであり、12kgf/mm2を超える場合には、劣化による引張強度の低下により、導体使用期間が減少するためである。
前記半導電層20の素材として用いられる高分子マトリックスを構成する基本樹脂として、低密度ポリエチレン、中密度ポリエチレン、高密度ポリエチレン、ポリプロピレン、エチレンメチルアクリレート(ethylene methyl acrylate)、エチレンビニルアクリレート、エチレンエチルアクリレート(EEA)、エチレンブチルアクリレート(EBA)、ポリアクリレート、ポリエステル、ポリカーボネート、ポリウレタン、ポリイミド、及びポリスチレンからなる群から選択される1種以上組み合わせて用いてもよい。
前記絶縁層30の素材として用いられる高分子マトリックスを構成する基本樹脂として、低密度ポリエチレン(LDPE)、中密度ポリエチレン、高密度ポリエチレン、及び超高分子量ポリエチレン(UHMW-PE)を単独で用いるか、2種以上混合して用いてもよい。
前記熱伝導層40の素材として用いられる高分子マトリックスを構成する基本樹脂として、低密度ポリエチレン(LDPE)、中密度ポリエチレン、高密度ポリエチレン、及び超高分子量ポリエチレン(UHMW-PE)を単独で用いるか、2種以上混合して用いてもよい。
前記耐候性被覆層50の素材として用いられる高分子マトリックスを構成する基本樹脂として、低密度ポリエチレン(LDPE)、中密度ポリエチレン、高密度ポリエチレン、及び超高分子量ポリエチレン(UHMW-PE)を単独で用いるか、2種以上混合して用いてもよい。
