Claims16
Cable comprising at least one elongated electrically conducting element, and at least one electrically insulating layer obtained from a polymer composition, wherein said electrically insulating layer is a non-crosslinked layer, and
- wherein said polymer composition includes at least one polypropylene-based thermoplastic polymer material and a dielectric liquid, and wherein the dielectric liquid comprises at least one mineral oil and at least one polar compound selected from benzophenone, acetophenone, a derivative of benzophenone, and a derivative of acetophenone.
Cable comprising at least one elongated electrically conducting element, and at least one electrically insulating layer obtained from a polymer composition wherein said electrically insulating layer is a non-crosslinked layer, and
- wherein said polymer composition includes at least one polypropylene-based thermoplastic polymer material and a dielectric liquid, and
- wherein the dielectric liquid comprises at least 70% by mass of mineral oil, relative to the total mass of the dielectric liquid, and at least 2.5% by mass of a polar compound selected from benzophenone, acetophenone, a derivative of benzophenone, and a derivative of acetophenone, relative to the total mass of the dielectric liquid.
