Power cable insulation lines: an overview of the technical innovation

The insulation process is executed by a well-proven, triple-layer crosshead equipped with an independent centering unit for each material flow channel distributor. The three water cooled extruders, MHV type, are designed to process sensitive polymer and elastomeric materials at a low melt temperature. Each heating/cooling zone is equipped with a separate heating and cooling element, directly applied to the barrel. Proportional valves connect directly to the PID control, guaranteeing very tight and stable melt temperature tolerances.

Controlled temperature stability

Cross-linking of the insulation materials is done by an inert gas (Nitrogen) pressurized within a catenary tube and heated up by 8 independent zones. The production parameters set-up is automatically adjusted and homogenized by the SAMP MHV-CAL software to reach maximum production speed while maintaining a constant insulation thickness. The cable is cooled by a gas circulation system, optionally also by water.

Unwinding and winding processes

The SAMP pay-offs and take-ups are engineered for maximum rigidity and stability to conveniently employ large reels. Fast speed and easy reel change contribute to the profitability of your existing line. A variety of safety features, supported by thorough testing and strict quality protocols during assembly and run-off, guarantee the operator's safety in daily production.
