Hysteresis Tension Type Taping Machine for Litz Wire

The word "Litz" comes from the German "Litzendraht". High-frequency Litz wire is made of multiple strands of mutually insulated single wires. It has good flexibility and operates at a frequency between 10kHz and 5MHz. Typical applications include: EV (Electric Vehicle), OBC (On-Board Charger), DC/DC converter, SMPS (Switching Power Supply), wireless charging, charging pile, transformer, frequency converter, motor, communication and IT equipment, ultrasonic equipment, Sonar equipment, radio equipment, induction heating, etc. High frequencies will produce eddy current losses, which increase as the current frequency increases. The root cause of these losses is the skin effect and proximity effect, which are overcome by using the twisted structure of high-frequency Litz wires. With adding additional insulation by covering the Litz wire using an insulating film, it can be suitable for applications that require high breakdown voltage and can withstand high bending and mechanical stress. By selecting the appropriate combination of film package material, quantity and overlapping ratio, the wrapping layers of Litz wire insulation tapes overlapped on each other to achieve appropriate insulation thickness, thereby improving the dielectric strength, breakdown voltage, heat resistance and flexibility. In order to prevent the film from detaching during or after the production process, self-adhesive film materials can also be used to wrap the wire core to meet the specified creepage distance. Since its establishment of 20 years ago, GEMWELL has provided more than 100 sets of wrapping machine production lines to a world-renowned litz wire manufacturer in Germany. The litz wire comes from GEMWELL wrapping machines, and GEMWELL is the leader in wrapping litz wire. The following configuration of Hysteresis Tension Type Taping Machine for Litz Wire is a conventional configuration of two wrapping heads. Users can increase or decrease the number of wrapping heads according to different cable manufacturing processes. Depending on the wire diameter specifications, the specifications and types of take-up, pay-off and capstan machines can also be customized and changed.
