Abstract: A medium-voltage or high-voltage power cable includes an elongated electrical conductor element, a first semiconducting layer, an electrically insulating layer, and a second semiconducting layer. The electrically insulating layer is at least one layer of a thermoplastic polymer material having a continuous polypropylene matrix in which a polyethylene is dispersed. A process for the preparation of such a cable is also provided.
