ESCONTEK

Semi-conductive compounds for MV and HV power cables

ESCONTEK compounds are designed to provide a semi-conductive layer over the conductor surface and over the insulation surface of a medium or high voltage cable to help ensure insulation electrical performance.

Quick Links

A semi-conductive layer over the conductor surface and over the insulation surface of a medium (MV) or high (HV) voltage cable help to ensure insulation electrical performance.  ESCONTEK semi-conductive compounds are designed with proper rheology for optimal processing on the CV lines and are manufactured with precision to ensure excellent dispersion of carbon black, an essential electrical ingredient.  Grades have good scorch resistance, allowing long run-times without degradation.  They also cross-link quickly in the CV tubes. 

  • Designed to process at high line speeds

  • High resistance to scorch

  • Cures quickly in CV tubes

  • Low volume resistivity at normal and emergency operating temp

  • Meets requirements of all applicable industry standards

  • Meticulously mixed for clean and smooth surface

  • Clean with minimal residue, and ionic impurities

  • Uniform carbon black compounding with no surface bumps or portrusions

  • Hands-on support for extrusion set-up

  • Allows higher product output
