The copper wire preheater is used for continuous heating of copper wires and other metal conductors under the action of electromagnetic induction during the coating process of copper wires or conductors to increase the attachment between the copper wire conductor and the outer casing. Focus on solving the problem of insufficient adhesion due to insufficient adhesion during wire processing, which is conducive to deep processing of wires. The preheater can be divided into power frequency 50Hz, intermediate frequency 350Hz, high frequency 4000Hz, etc. according to different types of wires.

Copper wire preheater features

1. Using the principle of induction heating, the spark damage on the surface of the core wire is small.

2. Suitable for high speed extrusion line (line speed from 100 meters to 2000 meters / minute)

3. The resistance to the core wire is small, and the core wire is not easy to stretch.

4. The output power automatically tracks the change of the speed to ensure the consistency of the preheating temperature at different line speeds.

5. The surface of the guide wheel is treated by ceramic spraying, which has a long service life.

6. Three-phase AC power supply is used to overcome the three-phase power imbalance caused by single-phase power supply.

7. Suitable for electronic line high-speed production line, physical, chemical foam production line, core wire conductor pre-heating of computer peripheral line production line.
