An electric conductor (10, 20, 30) provided with an insulating layer (11, 21, 31) and a protective layer (12, 22, 32), surrounding the conductor, in the form of a polymer material containing at least stabilized polyethylene. To said polyethylene there is added a combined antioxidant and voltage stabilizer, in the form of 5,10-dihydroindeno(1,2-b)indole or substituted forms thereof such as methyl, methoxy, dimethylamino or other donor substituents to counteract degradation as a result of electric load. |
