  • Field grading layer
    Patent number: 9666334
    Abstract: A method is provided for applying a field grading layer to a power cable includes preparing a polymer composition having a polymer matrix, at least one conductive filler different from a non-linear conductive organic filler, and at least one crosslinking agent. The method includes extruding the polymer composition into a crosslinkable field grading tape and winding the crosslinkable field grading tape onto a section of power cable in need of field grading. The crosslinkable tape is crosslinked to obtain a field grading layer.
    Type: Grant

  • FIELD GRADING LAYER
    Publication number: 20140182886
    Abstract: Method of applying a field grading layer to a power cable is disclosed. The method comprises compounding a polymer composition comprising a polymer matrix material, at least one non-linear conductive organic filler, and at least one crosslinking agent, extruding the compounded polymer composition into a crosslinkable field grading tape, winding the crosslinkable field grading tape onto a section of power cable in need of field grading curing and crosslinking the crosslinkable tape to obtain a field grading layer.
