INSULATED ELECTRIC CABLE

摘要

An insulated electric cable having a polymer based insulation system comprising an insulation layer (12; 22) and one or more semi-conductive layers (11; 13; 21; 23). The insulation layer is based on an electrically insulating polymeric composition and comprises a polar enriched surface zone having a suitable raised content of a suitable polar substance. The cable is in particular suitable for use in a system or installation for transmission or distribution of electric power or as a conductor in a high voltage winding in an electric machine.
