Problems solved by technology

[0007] Furthermore, since usually the insulating composition is a cross-linked polyolefin, the voltage stabilizer must be as compatible as possible with the commonly used cross-linking agents (such as organic peroxides), on the one hand so that the cross-linking process is not negatively affected, and on the other hand , the voltage stabilizer does not react or decompose, which will reduce its efficiency or even in the worst case deactivate it

Abstract

The present invention relates to a polyolefin composition comprising a polyolefin (A), a fullerene composition (B) which comprises: a C60 fullerene or a C60 chemical derivative selected from the group consisting of methanofullerene derivatives, PCBM derivatives, ThCBM derivatives, Prato derivatives, Bingel derivatives, diazoline derivatives, azafulleroid derivatives, ketolactam derivatives, and Diels-Alder derivatives; or a C70 fullerene or a C70 chemical derivative selected from the group consisting of methanofullerene derivatives, PCBM derivatives, ThCBM derivatives, Prato derivatives, Bingel derivatives, diazoline derivatives, azafulleroid derivatives, ketolactam derivatives, and Diels-Alder derivatives; or a blend of fullerenes; a master batch, a cable, and uses thereof.

Description

technical field [0001] The present invention relates to a polyolefin composition with improved electrical breakdown strength obtained by increasing the electrical treeing initiation field; to a masterbatch; to a polyolefin composition comprising the above polyolefin composition or A wire or cable of a masterbatch, especially a medium-voltage, high-voltage or extra-high-voltage cable; the use of said polyolefin composition or masterbatch for the preparation of a wire or cable, especially a medium-voltage, high-voltage or extra-high voltage cable; and It relates to the use of a fullerene composition as a voltage stabilizer in a polyolefin composition. Background technique [0002] Typically a typical medium voltage power cable for voltages from 6 to 72kV, a typical high voltage cable for voltages above 72kV and a typical extra high voltage cable for voltages above 220kV include one or more conductors in the cable core, The cable core is surrounded by several layers of polymer...
