| 20120031641 | MEDIUM-VOLTAGE CABLE - A cable for transmitting electrical power at a voltage between 5 and 49 kV includes a conductive cable core and an insulation layer for insulating the cable core, the insulation layer including from 50 to 99.9% of cross linked polyethylene, and from 0.1 to 50% of ethylene-alkyl(meth)acrylate and/or ethylene vinyl acetate. In at least one embodiment, the insulation layer is provided with a strippable outer semi conductive screen, which includes from 20 to 80% by weight of a composition of at least one copolymer selected from the group consisting of ethylene-alkyl (meth)acrylate carbon monoxides. The combination of materials in the insulator and the semi conductive screen provides for high water-tree resistance of the insulator and strippability of the semi conductive screen. | 02-09-2012 |
