0.05 - 0.287MM SELF BONDING WIRE HIGH FREQUENCY COPPER LITZ WIRE INSULATED WINDING WIRE FOR TRANSFORMERS

Litz wire is a type of cable used in electronics to carry alternating current. The wire is designed to reduce the skin effect and proximity effect losses in conductors used at frequencies up to about 1 MHz. It consists of many thin wire strands, individually insulated and twisted or woven together, following one of several carefully prescribed patterns often involving several levels (groups of twisted wires are twisted together, etc.). The result of these winding patterns is to equalize the proportion of the overall length over which each strand is at the outside of the conductor, an effect not achieved with simple twisted-strand hookup wire.

FEATURES

The performance of a litz wire is determined by its electrical, mechanical, thermal and chemical features and performance attributes. While the thermal and chemical demands are fulfilled by selection of suitable insulation materials, the electrical and mechanical features depend mainly on the chosen parameters of the bunching construction.

The following table gives an overview of the mutual influence of the construction parameters on the most important electrical and mechanical features of a litz wire.

APPLICATION

Litz wire is used to make inductors and transformers, especially for high frequency applications where the skin effect is more pronounced and proximity effect can be an even more severe problem. Litz wire is one kind of stranded wire, but, in this case, the reason for its use is not the usual one of avoiding complete wire breakage due to material fatigue..
