Abstract

Electrical cable particularly for high voltage direct current transmission having at least once conductor and at least one extruded insulating coating layer of a polymeric composition. The polymeric composition is a polyethylene modified with at least one compound of formula (I): in which R represents H or CH3; R1 represents a linear or branched, preferably linear, C1-C8 alkylene group; R2 represents OH; a group OR3 in which R3 represents a linear or branched C1-C4 alkyl group, a group NR4R5 in which R4 and R5, which may be identical or different, represent H, or a linear or branched C1-C4 alkyl group, and related insulating composition.
