Abstract
A process is provided for manufacturing a cable having at least one electrically insulating layer obtained from a polymer composition having at least one thermoplastic polymer material based on polypropylene and polyethylene, at least one dielectric liquid, and at least one thermally conductive inorganic filler. The process includes the premixing of the thermally conductive inorganic filler with the polyethylene.
Claims15
A process for manufacturing an electric cable having at least one elongated electrically conductive element and at least one electrically insulating layer obtained from a polymer composition having at least one thermoplastic polymer material based on polypropylene and polyethylene, at least one dielectric liquid, and at least one thermally conductive inorganic nanofiller, said process comprising steps of:
- i) mixing the nanometric thermally conductive inorganic nanofiller with an ethylene polymer to form a nanofilled ethylene polymer,
- ii) mixing the nanofilled ethylene polymer with at least one propylene polymer, to form a nanofilled thermoplastic polymer material,
- iii) mixing the nanofilled thermoplastic polymer material with the dielectric liquid to form a polymer composition, and
- iv) extruding the polymer composition around the elongated electrically conductive element.
