Electrical cable having at least one conducting element, at least one polyolefin-based insulating covering layer, in which said insulating covering layer has at least one voltage stabilizer, said voltage stabilizer being a benzophenone substituted with at least one group selected from alkyl, arylalkyl and alkylaryl wherein said group: a) is linked to a phenyl ring of the benzophenone directly or via an oxygen bridge (-O-); b) contains, optionally, one or more oxygen bridges (-O-); and c) is optionally linked to a phenyl ring of at least one or other benzophenone group, provided that when said at least one group is an alkyl, optionally substituted, the carbon atom of said alkyl which is directly linked to a phenyl ring of said benzophenone is tertiary. A polyolefin-based insulating composition having at least one voltage stabilizer as described above. |
