FIELD: cable engineering.
SUBSTANCE: proposed cable has at least one electrical conductor and at least one extruded sheathing layer based on thermoplastic polymeric material mixed up with insulating liquid wherein mentioned thermoplastic polymeric material is chosen from (a) at least one homopolymer of propylene or at least one copolymer with at least one olefin comonomer; (b) mechanical mixture that has at least one homopolymer or copolymer of propylene (a) and at least one elastomeric copolymer of ethylene with at least one aliphatic α-olefin, and (arbitrarily) polyene.
EFFECT: improved mechanical and electrical properties including high dielectric strength, which provide in particular, for its use at high operating temperatures.
