Heat treatment induction heater / for cables

At the manufacture of cables, specifically automotive and data cables, a reliable conductor preheating is required, to ensure optimum adhesion and controlled foaming of the insulation on the wire and the data cable, respectively. With the PREHEATER 6000 TC (Temperature Controlled) SIKORA offers an advanced solution for a precise conductor preheating - the basis for high-quality cable production.

Unique is the measurement of the wire temperature inside the PREHEATER 6000 TC by a non-contact infrared camera and its direct feedback to the power control, for a precise control of the preheating power. The PREHEATER 6000 TC is positioned before the extruder and preheats the wire by means of inductive heating depending on the product type up to 150 °C (optional: 250 °C). It operates at a heating frequency of 2,400 Hz and a maximum power of 30 kW.

Innovative temperature measurement and control
In many applications it may be sufficient to control the output power of a conductor preheating device only depending on the conductor size and type, the line speed and the required temperature. However, there are numerous influences on the accuracy of the conductor temperature - the ambient temperature, the initial temperature of the conductor and in particular the development of the temperature of the wire guiding short-circuit wheel within the first 10 to 20 minutes after starting the production or after an interruption of the production.
