Product introduction:

Induction heating principle is applied to preheat the copper core wire before extruding, which can obviously improve the extruding quality of insulating layer, and is an essential device for the production of high quality wire and cable. Compared with other forms of preheating device, the equipment has simple structure and high reliability.

The frequency induction preheater has the following characteristics:

1. using the principle of induction heating, the electric spark damage to the surface of the core is less.
2., the resistance of the core line is small, and the core line is not easy to stretch.
3. the output power automatically tracks the change of speed to ensure the consistency of the preheating temperature at different line speeds.
