Abstract

"CABO ELéTRICO COMPOSIçãO ISOLANTE, E, MéTODO PARA REDUZIR A ACUMULAçãO DE CARGAS ESPACIAIS EM UM CABO ELéTRICO DURANTE A TRANSMISSãO OU DISTRIBUIçãO DE CORRENTE CONTìNUA DE ALTA VOLTAGEM". Cabo elétrico, particularmente para transmissão de corrente contínua de alta voltagem, compreendendo pelo menos um condutor e pelo menos uma camada de revestimento isolante extrusada consistindo de uma composição polimérica que compreende um polietileno modificado com pelo menos um composto da fórmula (I): em que R representa H OU CH~ 3~; R~ 1~ representa grupo alquileno C~ 1~-C~ 8~ linear ou ramificado, preferivelmente linear; R~ 2~ representa OH; um grupo OR~ 3~ em que R~ 3~ representa um grupo alquila C~ 1~-C~ 4~ linear ou ramificado; um grupo NR~ 4~R~ 5~ em que R~ 4~ e R~ 5~, que podem ser idênticos ou diferentes, representam H, ou um grupo alquila C~ 1~-C~ 4~ linear ou ramificado; e composição isolante relacionada.
