Product Description

Product Description

  Enamelled stranded wire, also known as multi-strand wire, Litz wire, refers to the multi-strand enameled wire single wire of the same specification, tightly concentrically twisted, the twisting direction of each layer is alternately reversed, with a specific laying distance, twisted together insulated wire.
  The Litz wire is actually made up of independent insulated conductors twisted wires. It can also be considered as solid wire twisted together. litz wire, also known as enameled stranded wire, is divided into ordinary and self-adhesive types,film wrapped.

Stranded enameled wire is a multi-strand enameled wire that is twisted by a machine, and its voltage needs to be confirmed according to the number of strands. The more the number of strands, the lower the voltage standard, and the details are multiplied by the standard of the enameled wire. Refer to (JISC3202-1994 ).
When the number of strands (N) < 20, the breakdown of the stranded wire is V = breakdown voltage of a single enameled wire * 90%.
When the number of strands is 20≤N<60, the breakdown voltage of the stranded wire is V=the breakdown voltage of a single enameled wire*80%.
When the number of strands is 60≤N<120, the breakdown voltage of the stranded wire is V=the breakdown voltage of a single enameled wire*70%.
When the number of strands is N≥120, the breakdown voltage of the stranded wire is V=the breakdown voltage of a single enameled wire*60%.


Stranding direction refers to the direction of wire take-up in the production process, generally divided into forward (S) that is clockwise, reverse (Z) is counterclockwise
Twisting distance The ratio of the effective measurement distance to the number of turns of the turning will be set by calculation, which is the twisting distance (pitch) of the stranded wire, 4-110mm

Product advantages

1. Good flexibility
2. High frequency performance. High frequency Litz Wire is made up of multiple insulated single wires twisted together, typically used for applications with operating frequencies between 10 kHz and 5 MHz. In the application of magnetic energy storage coils, high frequencies will generate eddy current losses. Eddy current losses increase with the increase of current frequency. 
3. Widely applicable.
