| description | To provide an insulating resin composition for a power cable, a power cable, and a power cable connection part which are excellent in flexibility and electric insulation property, and can suppress thermal deformation and a sag, without performing a crosslinking step.SOLUTION: An insulating resin composition for a power cable contains a polypropylene resin (A) that is a propylene-based polymer, and a styrenic thermoplastic elastomer (B), wherein a temperature characteristic curve of a loss tangent tanδ obtained by dynamic viscoelastic measurement at a frequency of 100 rad/s has a high temperature side temperature region where the loss tangent tanδ is 0.1 or more and 0.4 or less, and a low temperature side temperature region where the loss tangent tanδ is less than 0.1, and the highest temperature in the high temperature side temperature region is 240°C or higher.SELECTED DRAWING: Figure 1
【課題】架橋工程を行わなくても、可撓性および電気絶縁性に優れ、熱変形およびサグを抑制できる電力ケーブル用絶縁性樹脂組成物、電力ケーブルおよび電力ケーブル接続部を提供する。【解決手段】電力ケーブル用絶縁性樹脂組成物は、プロピレン系重合体であるポリプロピレン樹脂（Ａ）と、スチレン系熱可塑性エラストマー（Ｂ）と、を含有し、周波数１００ｒａｄ／ｓの動的粘弾性測定で得られる損失正接ｔａｎδの温度特性曲線は、損失正接ｔａｎδが０．１以上０．４以下の高温側温度領域と損失正接ｔａｎδが０．１未満の低温側温度領域とを有し、前記高温側温度領域の最高温度は２４０℃以上である。【選択図】図１ |
