Semi-conductive Compounds

Xinda compounding lines

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

Since Xinda Co-Kneader can realize the perfect dispersion of high structured carbon black into the polymer matrix. Xinda Co-Kneader becomes the ideal choice of manufacturing the semi-conductive compounds. It can help achieve the desired conductivity with excellent distribution of the carbon black without damaging the original structure of the carbon black.

Xinda Co-Kneader compounding line is suitable for making the Semi-conductive cable compounds such as:

  • Thermoplastic semi-conductive conductor screen for XLPE-insulated cables
  • Semi-conductive crosslinkable conductor screen for XLPE cable up to 10kV
  • Strippable semi-conductive crosslinkable insulation screen for XLPE cables up to 10kV
  • Semi-conductive crosslinkable conductor screen for XLPE cable up to 35kV
  • Strippable semi-conductive crosslinkable insulation screen for XLPE cables up to 35kV
  • Semi-conductive crosslinkable conductor screen for XLPE cable up to 110kV
  • Strippable semi-conductive crosslinkable insulation screen for XLPE cables up to 110kV

Why XINDA Co-Kneader is suitable for Semi-conductive compounds

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

  • High dispersion of carbon black
  • High filling rate of carbon black
  • Flexible liquid injection position
  • Gentle shearing minimize damage to high structure carbon black
  • Precise temperature control minimize polymer degradation
  • Flexible screw configuration
