Extruder & Crosshead

Triple extrusion lines have three extruders connected to one common three-layer crosshead for the simultaneous extrusion of conductor screen layer, insulation layer and insulation screen layer.

Control System

Highly resistant to interference, minimum fluctuation of cables in tube, ensuring stable running and easy to maintain;
Control system is placed at the middle part of heating zone, it can protect cables from contacting the tube wall during heating process;
When the control receives the signal of cable position, the rotation speed of lower capstan (pulling) will be adjusted accordantly;
