Litz wire / High frequency litz wire
Stranded wires are specially manufactured copper strands that are individually insulated and baked into a bundle. In detail, the Litz wire consists of individual (ultra) fine enameled copper wires. The purpose of this is to minimize certain negative electrical effects (skin effect, proximity).
The product is also called high-frequency Litz wire because these negative effects only occur above approx. 50 kHz. In order to minimize additional negative electromagnetic effects, the individual copper strands are arranged randomly.
This opens up various areas of application, such as motor windings, inductive charging stations, or heating elements. However, stranded wires are also being used more and more frequently in general e-mobility, as energy efficiency can be increased, especially in high-frequency ranges.
