Litz wire consists of multiple insulated strands of wire twisted or woven into a specific geometric pattern. This design allows each strand to occupy every position within the cable over its length. The primary advantage of this configuration is to minimize losses due to the tendency of high-frequency currents to flow primarily on the surface of conductors. We offer a diverse range of Litz wire configurations, from fine wire strands to superflex cables up to four inches in diameter.
Litz wire enhances the efficiency of transformers and motors by reducing AC losses from skin and proximity effects at high frequencies. The construction involves individually insulated strands arranged to ensure even distribution of current across all strands, thus improving overall current-carrying efficiency.
Applications:
- High-frequency inductors and transformers
- Motors
- Relays
- Inverters
- Power supplies
- Ultrasonic and sonar equipment
- Heat-induction equipment
- High-twist applications, up to 300 turns per foot
Our Litz wire comes in various configurations tailored to specific frequencies, voltages, and current-carrying needs. Strands range from 50 to 16 AWG, with configurations from a few strands to several thousand. We offer traditional round conductors as well as space-saving square and rectangular cross sections for maximum copper density.
Popular configurations include 60 strands of 36 AWG, 100 strands of 38 AWG, and 2100 strands of 36 AWG.
What is Litz Wire?
Litz wire is a specialized cable made by bundling multiple thin, insulated wires side by side. This construction allows it to efficiently carry high-frequency currents by distributing the current across all the strands, which minimizes losses from the skin effect. Litz wire is widely used in applications such as radio frequency (RF) systems, high-frequency power circuits, induction heaters, and Tesla coils.
The strands in Litz wire are typically twisted together in one or multiple bunches, forming a larger cable. This twisting helps manage the magnetic fields around the wires, ensuring even current flow and reducing losses.
Where can I buy Litz wire?
We offer a variety of Litz wire sizes and provide soldering services for ready-to-use Litz cable assemblies. If you require a specific size that we do not have in stock, we can custom-manufacture it to meet your needs.
