Abstract

CABO, COMPOSIçãO DE POLìMERO, MATERIAL DE POLìMERO TERMOPLáSTICO, E, USO DE UMA COMPOSIçãO DE POLìMERO. Um cabo é descrito compreendendo pelo menos um condutor elétrico e pelo menos uma camada de cobertura extrusada incluindo um material de polímero termoplástico em mistura com um líquido dielétrico, em que o material de polímero termoplástico compreende (a) pelo menos 75 % em peso, com respeito ao peso total do material de polímero termoplástico, de pelo menos um copolímero de pelo menos dois co-monómeros de cL-olefina, o copolímero tendo uma entalpia de fusão mais baixa do que 25 J/g; e (b) uma quantidade igual a ou menor do que 25 % em peso com respeito ao peso total do material de polímero termoplástico de pelo menos um homopolímero de propileno ou copolímero de propileno com pelo menos uma cL-olefina, pelo menos um homopolímero de propileno ou copolímero de propileno tendo uma entalpia de fusão mais alta do que 25 J/g e um ponto de fusão mais alto do que 130°C. De acordo com a invenção, a camada de cobertura tem uma entalpia de fusão igual a ou mais baixa do que 40 J/g, e a concentração em peso do líquido dielétrico no material de polímero termoplástico é mais baixa do que a concentração de saturação do líquido dielétrico no material de polímero termoplástico.
