Product introduction:
The induction heating principle is adopted in the high frequency induction preheater to preheat the copper core wire before extrusion, which can obviously improve the extruding quality of the insulation layer, and is an essential device for the production of high quality wire and cable.
The following features of high frequency induction preheater are introduced.
1. using the principle of induction heating, the electric spark damage to the surface of the core is less.
2. suitable for high speed extrusion line
3., the resistance of the core line is small, and the core line is not easy to stretch.
4. the output power automatically tracks the change of speed to ensure the consistency of the preheating temperature at different line speeds.
The surface of the 5. guide wheel is sprayed by ceramic, and the length of life is long.
The three-phase AC power supply is used in the high frequency induction preheater, which overcomes the unbalanced three-phase power supply caused by the single phase power supply.
