Abstract (en)
[origin: EP2498263A1] The medium or high voltage electric cable (1) comprises an electric conductor (2), a first semiconducting layer (3) surrounding the electric conductor, a second electrically insulating layer (4) surrounding the first semiconducting layer, and a third semiconducting layer (5) surrounding the second electrically insulating layer. The layers are crosslinked layers obtained from a crosslinkable composition including 50-100 parts by weight (pbw) of polyolefin and aliphatic peroxide such as crosslinking agent. The composition comprises an aromatic compound including an aromatic ring. The medium or high voltage electric cable (1) comprises an electric conductor (2), a first semiconducting layer (3) surrounding the electric conductor, a second electrically insulating layer (4) surrounding the first semiconducting layer, and a third semiconducting layer (5) surrounding the second electrically insulating layer. The layers are crosslinked layers obtained from a crosslinkable composition including 50-100 parts by weight (pbw) of polyolefin and aliphatic peroxide such as crosslinking agent. The composition comprises: an aromatic compound including an aromatic ring; a reactive single function adapted to its grafting with the polyolefin; and a crosslinking coagent having identical or different reactive functions, which are adapted to be grafted with the polyolefin and to be crosslinked with the polyolefin and are a vinyl function of CH 2=CH-. The crosslinked layers are electrically insulating layers.
