Elektrisola offers an exceptionally wide range of highfrequency litz wires. Due to the different demands resulting from the broad field of applications there are several types of litz wires in different variants available.
Basic litz wire
According to the respective application, litz wire can be constructed for optimized heating - or high frequency performance. By a suitable choice of conductor materials, number of single wires, constructions and dimensions a high number of cost efficient variants for a wide range of applications can be offered.
Served, taped and extruded litz wires
For application areas with high demands for mechanical, electrical or chemical resistivity litz wires can be additionally coated with different materials. Textile serving gives litz wires a good form stability and robustness. Foil taping at the same time increases the electrical breakdown voltage, and extrusion coating can significantly improve the flex life-performance. In general several features can be improved at the same time, but for this a balanced design of the litz wire construction is needed.
Litz wires with profiling and litz wires with strain relief
The copper filling factor is very important for many fields of application. For optimization HF-litz wires can be profiled with a predefined square or rectangular shape. The quality of the single wires must not be affected by this.
Litz wires which are expected to be highly stressed by mechanical tension or bending cyles can be additionally protected by using an application specific strain relief.
EFOLIT and Smartbond: Litz wire products for special applications
For especially high demands for electrical breakdown voltage with simultaneous demand for high mechanical stress, Elektrisola offers the VDE-certified EFOLIT product family. These litz wires with reinforced multilayer tape insulation cover different voltage- and temperature ranges.
Special demands also exist for wireless energy transmission and here with focus on the production of inductive charger systems for multimedia devices. For these applications the thermal activated bondable Smartbond-litz wire type has been developed by Elektrisola. Also these variants are available in several and also customer specific designs.
