High Frequescy Enamelled Copper Litz Wires Manufacturer
Litz Wire: A Revolution in High-Frequency Electrical Conductivity
Litz wire is a specialized type of multi-stranded wire designed to reduce energy losses caused by the skin effect and proximity effect in high-frequency applications. Unlike standard conductors, litz wire is made up of multiple individually insulated strands twisted or braided in a specific pattern to improve efficiency. This unique construction allows it to handle alternating current (AC) more effectively than traditional solid or stranded wires.In this article, we’ll explore the various aspects of litz wire, including its construction, types, applications, and why it is the preferred choice for industries ranging from transformers to wireless power systems. Whether you’re a manufacturer, engineer, or industry expert, this guide will provide valuable insights into the benefits of using litz wire and how it can reduce AC losses in your designs.
What is Litz Wire?
Litz wire is short for “litzendraht,” a German term meaning “woven wire.” It is a conductor made up of many individually insulated strands that are twisted or braided in a specific pattern. This design minimizes energy losses caused by the skin effect and proximity effect, phenomena that occur in high-frequency AC circuits where current tends to flow on the surface of a conductor rather than evenly across its cross-section.
Key Features of Litz Wire
- Reduced AC Losses: The braided or twisted pattern ensures uniform current distribution, reducing energy losses.
- High-Frequency Efficiency: Perfectly suited for high-frequency power applications such as transformers, inductors, and wireless charging systems.
- Customization Options: Available in a variety of strand counts, sizes, and insulation materials to meet specific performance requirements.
How is Litz Wire Constructed?
The construction of litz wire involves twisting or braiding multiple individually insulated strands of magnet wire. These strands are arranged in a uniform pattern to ensure that each strand occupies every position in the cross-section of the wire equally over its length. This helps mitigate the uneven current distribution caused by the skin depth effect in high-frequency applications.
Materials Used
- Copper Wire: The primary conductor, offering excellent electrical conductivity.
- Insulation: Includes materials such as polyester, nylon, or enamel to protect individual strands and prevent short circuits.
- Outer Insulation: In some cases, the litz wire is further enclosed in an additional jacket for mechanical protection.
Types of Litz Wire
What Are the Key Litz Wire Types?
Litz wire comes in various types, each tailored to specific applications. These include:
- Unserved Litz Wire: Basic construction without additional outer protection.
- Served Litz Wire: Includes a protective layer of silk, nylon, or textile for enhanced durability and smoother winding.
- Custom Litz Wire: Fully customizable designs to meet unique requirements, such as specific strand counts, insulation materials, or thermal ratings.
Each type offers unique benefits depending on the application, from wire used in transformers to high-frequency litz wire in wireless power systems.
How Does Litz Wire Reduce AC Losses?
Understanding AC Losses in High-Frequency Applications
In high-frequency applications, AC losses occur due to the skin effect (current flowing on the surface of the conductor) and the proximity effect (interaction of magnetic fields between nearby conductors). These effects increase the resistance of the wire, reducing efficiency.
How Litz Wire Mitigates These Effects
- Skin Effect Reduction: By breaking the conductor into multiple individually insulated strands, litz wire ensures that current flows more evenly, reducing resistance.
- Proximity Effect Mitigation: The twisted or braided pattern minimizes magnetic field interactions, further reducing energy losses.
Using litz wire in high-frequency designs significantly improves efficiency and reduces heat generation.
Applications of Litz Wire

2. Evaluate Thermal Requirements
Choose a thermal class that can handle the heat generated in your application. Options range from 155°C to 220°C, depending on the insulation material.
3. Strand Count and Diameter
The number of strands and their diameter determine the wire’s current-carrying capacity. Applications requiring higher currents benefit from larger strand counts.
How is Litz Wire Manufactured?
The manufacturing process of litz wire involves:
- Stranding: Multiple individually insulated strands are twisted or braided together.
