<p>Cable, in particular for medium-voltage or high-voltage electrical power transmission or distribution, for telecommunications or for data transmission, comprising a conductor and at least one coating layer based on a non-crosslinked polymer material comprising a heterogeneous copolymer with an ethylene-based elastomeric phase copolymerized with an α-olefin and a propylene-based thermoplastic phase, in which the said elastomeric phase in the said heterogeneous copolymer is at least 45 % by weight relative to the total weight of the heterogeneous copolymer, and the said heterogeneous copolymer is essentially free of crystallinity deriving from polyethylene sequences.</p> |
