ENERGY CABLE HAVING A COLD-STRIPPABLE SEMICONDUCTIVE LAYER

Energy cable comprising, from the interior to the exterior, an electrical conductor, an inner semiconductive layer, an electrically insulating layer made from a thermoplastic material in admixture with a dielectric fluid, and an outer semiconductive layer, wherein the outer semiconductive layer comprises: (i) from 55 wt % to 90 wt % of a copolymer of ethylene with at least one ester comonomer having an ethylenic unsaturation; (ii) from 10 wt % to 45 wt % of a propylene copolymer with at least one olefin comonomer selected from ethylene and an α-olefin other than propylene, said copolymer having a melting point of from 145° C. to 170° C. and a melting enthalpy of from 40 J/g to 80 J/g; (iii) at least one conductive filler; (iv) at least one dielectric fluid; the amounts of (i) and (ii) being expressed with respect to the total weight of the polymeric components of the layer. The outer semiconductive layer is cold-strippable, having an adhesion with the underlying thermoplastic insulating layer which can be tuned so as to obtain a suitable balance between strippability at a temperature ranging from about 0° C. to about 40° C., without applying heat, and stable adhesion with the insulating layer during the cable lifespan.
