How Does SST-Litz Wire Work?
At low frequencies, electric current flows almost uniformly through a conductor. However, as frequency increases, current naturally moves toward the outer surface of the conductor.
This phenomenon is known as the skin effect.
When multiple conductors are placed close together, their magnetic fields also influence one another, causing the current distribution to become even less uniform. This is called the proximity effect.
Both effects increase AC resistance, generate additional heat, and reduce overall system efficiency.
SST-Litz Wire solves these problems by dividing one large conductor into hundreds or even thousands of insulated fine strands. Since each strand continuously changes position within the bundle, every strand experiences nearly identical magnetic conditions, allowing current to distribute evenly throughout the conductor.
The result is significantly lower AC losses compared with conventional solid or standard stranded conductors.
Key Features of SST-Litz Wire
SST-Litz Wire offers several performance advantages that make it ideal for high-frequency electrical equipment.
Individually Insulated Strands
Each copper strand is coated with a thin insulation layer that prevents circulating eddy currents between strands.
Optimized Strand Transposition
The strands are woven according to precise patterns so every conductor occupies different positions throughout the cable, improving current balance.
Low AC Resistance
By minimizing skin and proximity effects, SST-Litz Wire greatly reduces AC resistance at medium and high frequencies.
Excellent Flexibility
Despite containing hundreds of strands, the finished conductor remains flexible and easy to wind around transformer cores or motor stators.
Improved Thermal Performance
Lower electrical losses translate into reduced operating temperatures and longer equipment life.
