Product Introduction
Flat Litz wire is made by twisting and flattening multiple fine copper wire strands. It's suitable for high-frequency electrical equipment such as motor stators, transformer coils, maglev trains, and wireless charging, effectively reducing eddy current losses.

During production, each wire is transposed to ensure low eddy current losses. Litz wire boasts a maximum width-to-width ratio of 20:1, and its rectangular cross-section effectively increases the fill factor of electric motors. This wire has been successfully used in stator coils for China Aerospace Science and Industry Corporation's high-speed train (magnetic levitation + vacuum tube) project. |
Material
Flat litz wire is made of high-purity oxygen-free copper wire, some of which are available with silver-plated copper or tin-plated copper.
Bonding Method
During production, each strand of copper wire is transposed, and multiple strands are arranged in parallel and pressed into a rectangular or flat ribbon structure.
Shape
Rectangular flat cross-section, with a maximum wire-to-width ratio of 20:1. Custom sizes can be customized to suit motor slot widths.
Surface Insulation Material
Polyester film enamel, polyamide enamel, or multi-layer polyester insulation film are used to ensure high-frequency insulation performance and heat resistance.
Packing Reference
Available in cylindrical wooden/plastic spools, tapered plastic spools, IPPC wooden pallets, or wooden boxes.
Shipping Options
Flat litz wire can be shipped by air, sea, road or container.
Frequently Asked Questions
Q: What payment methods do you accept?
A: We typically accept common international payment methods such as T/T (Wire Transfer) and L/C (Letter of Credit). Long-term customers can negotiate more flexible payment terms.
Q: What if there is a problem with the product I receive?
A: Please contact us immediately upon receipt. We will promptly investigate the cause and provide a return, exchange, or reissue service to ensure your safety.
Q: Do you provide samples?
A: Yes. We provide standard samples for testing purposes, and some samples are provided free of charge. Shipping costs are borne by the customer.
Q: What are the main applications of flat litz wire?
A: High-frequency transformers, motor stators, maglev trains, and wireless charging coils.
Q: How do I clean flat litz wire?
A: Use a dry cloth and avoid using corrosive chemical solvents.
Q: What precautions should be taken during installation?
A: Keep the coils tightly wound to avoid damaging the insulation.
Q: Is it bendable?
A: It can be bent repeatedly and remains flexible without affecting its conductivity.
Q: Can it be cut?
A: It can be cut to your specifications, but the ends will require re-insulation.
Q: Is it customizable?
A: We can customize the wire diameter, strand count, insulation type, and length.
Q: What are the storage conditions?
A: Flat litz wire should be stored in a dry, well-ventilated area, away from heat and humidity.
