about the extruder
Semi-conductive Cable Compounds
Semi-conductive cable compounds are used in the wire and cable industry as two semi-conductive layers for enclosing crosslinked Polyethylene (XLPE) layers to ensure the insulation performance of medium- and high-voltage power cables. The production process requires that the conductive carbon black structure is not destroyed, highly dispersed into a polymer matrix, and evenly distributed to the melts to obtain a homogeneous compound. At the same time, the polymer is required to be degraded as little as possible.
