THC 70/150 HE Crosshead

A perfect solution for medium and high-voltage PP-insulated cable production. The optimised helical distributor enables accurate wall thickness, centricity and roundness of the cable. The helical design increases overlapping in the insulation seam area, thus improving the cable’s electrical properties. Short residence times, streamlined flow channels and efficient electric heating favour long production lengths and smooth layer surfaces. The centring of all layers can be adjusted independently. Conical flow pieces are made of nitrided steel to ensure continuity in production for many years.


  • Three-layer extrusion for MV and HV PP insulations up to 500 kV
  • Accurate cable dimensions
  • Long continuous production lengths
  • Wide production range
  • Easy handling with low damage risk
  • Fast setup time.
