High Voltage 0.1mm*127 PI Insulation Taped Litz Wire

Short Description:

Taped litz wire 0.1mm*127 : This type of tape litz wire uses an enameled round copper wire with a single wire of 0.1mm (38awg), the temperature resistance rating is 180 degrees. The number of strands of this taped litz wire is 127, and it is wrapped with a golden PI film, which has good pressure resistance and high performance, and it also provides good electrical isolation.

The taped litz wire refers to the reinforced insulating stranded wire that is wrapped with one or more insulating films outside the ordinary stranded wire according to a certain overlap rate. It has the advantages of good voltage resistance and high mechanical strength. The operating voltage of the litz wire is up to 10000V The working frequency can reach 500kHz, which can be widely used in various high-frequency and high-voltage electric energy conversion equipment.

At present, the diameter of the single wire of the litz wire we produce is 0.03 to 1.0 mm, the number of strands is 2 to 7000, and the maximum finished outer diameter is 12 mm. The thermal rating of individual wire is 155 degrees, and 180 degrees. The type of insulation film is polyurethane, and the materials are polyester film (PET), PTFE film (F4) and polyimide film( PI).
