| 摘要 |
Electrical cable comprising at least one conducting element, at least one polyolefin-based insulating covering layer, in which the said insulating covering layer comprises at least one voltage stabilizer, in which the said voltage stabilizer is a benzophenone substituted with at least one group selected from alkyl, arylalkyl and alkylaryl and in that the 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 other benzophenone group, provided that when said at least one group is an alkyl, optionally substituted, the carbon atom of the said alkyl which is directly linked to a phenyl ring of the said benzophenone is tertiary. A polyolefin-based insulating composition comprising at least one voltage stabilizer as defined above. |
