A new member of our conical crosshead family – THC 50/90. It’s a perfect solution for medium and high-voltage cable production.

Its optimized Bi-Flow distributors enable accurate wall thickness, centricity, and roundness of the cable. Short residence times, streamlined flow channels and efficient water tempering allows long production lengths and smooth layer surfaces.

The centering of all layers can be adjusted independently. Conical flow pieces are made of nitrided steel to ensure continuity in production for many years.

Benefits

  • Three-layer extrusion for MV and HV insulations up to 132 kV
  • Accurate cable dimensions
  • Long continuous production lengths
  • Wide production range
  • Easy handling with low damage risk
  • Fast setup time.
