Abstract (en)
[origin: EP2498264A1] The medium or high voltage electric cable (1) comprises an elongated conductive member (2) surrounded by a polymeric layer (3, 4, 5). The polymeric layer is a non-crosslinking layer obtained from a composition including a thermoplastic polymer (50-100 parts by weight) such as monomodal polyolefin having a capillary viscosity (eta ) of 0.80 Pa.s at 170[deg] C and at 230[deg] C with a shear of 0.1 s -> 1>. A density of the thermoplastic polymer at 23[deg] C is 941 kg/m 3>, and a melting temperature of the thermoplastic polymer is 130[deg] C. The medium or high voltage electric cable (1) comprises an elongated conductive member (2) surrounded by a polymeric layer (3, 4, 5). The polymeric layer is a non-crosslinking layer obtained from a composition including a thermoplastic polymer (50-100 parts by weight) such as monomodal polyolefin having a capillary viscosity (eta ) of 0.80 Pa.s at 170[deg] C and at 230[deg] C with a shear of 0.1 s -> 1>. A density of the thermoplastic polymer at 23[deg] C is 941 kg/m 3>, and a melting temperature of the thermoplastic polymer is 130[deg] C. A ratio of weight average molecular weight of the thermoplastic polymer and number average molecular weight of the thermoplastic polymer is 5-7. A melt flow index of the thermoplastic polymer is 0.1-2 g/10 minutes. The layers are crosslinked layers, which are electrically insulating layers.
