Кабел литцендрат

We’re offering different copper litz wires with round and square sections.  In case when using typical wires is impossible and not effective we recommend using litz wires.

Litz is a wire made of individually twisted copper wires insulated with glaze. It can be used in devices like transformers, inverters and pulse power supplies.

Litz - construction: in silk, nylon and kapton insulation. 

Skin effect

During transferring low frequency data (at least several hundreds Hz) occurs a skin effect, which “pulls out” current media from the center of the wire to its surface layer. This effect causes disrupted density of the current* in the axial section. Litz is a wire made of many thin strains insulated with varnish. In the strain with a small axial section a more effective ratio of active section conducting current to the section in which there is no current is achieved. A method to lower skin effect results, we have to decrease the sector of a single action wire through using thin cables - litz.

*The density of a current in the wire’s strain increases from its center to the external edge. In critical cases though the center part of a wire, the current flow can be non-existent. With an increase of frequency, the overload of wires decreases.
