Method of applying a field grading layer to a power cable is disclosed. The method comprises the following steps:
i) preparing a polymer composition comprising a polymer matrix, at least one conductive filler different from a non-linear conductive organic filler, and at least one crosslinking agent,
ii) extruding the polymer composition into a crosslinkable field grading tape,
iii) winding the crosslinkable field grading tape onto a section of power cable in need of field grading, and
iv) crosslinking the crosslinkable tape to obtain a field grading layer. |
