摘要:
Cable including at least one core comprising at least one transmissive element and at least one coating layer made of a coating material, wherein said coating material comprises: —at least one polyethylene; —at least one non-ionic surfactant having the following general formula (I): wherein: —Q is a p-functional group; —R is a linear or branched C1-C4 alkyl group, preferably a methyl group; —R1 is a hydrogen atom or a linear or branched C1-C6 alkyl group, preferably a hydrogen atom; —n is an integer from 2 to 5 inclusive, preferably 2; —x is an integer from 5 to 500 inclusive, preferably from 10 to 300 inclusive; —y is an integer from 0 to 500 inclusive, preferably from 10 to 300 inclusive; —z is an integer from 0 to 500 inclusive, preferably from 10 to 300 inclusive; —y+z is not lower than 2; —p is an integer from 1 to 4 inclusive, preferably 1 or 4; provided that, when the transmissive element is an electrical energy transmissive element, said at least one coating layer is an external sheathing layer. Preferably, said coating layer is an external sheathing layer having a protective function.
