The result is a wire product that combines the unique benefits of litz wire with enhanced mechanical and electrical properties, making it perfect for transformers, motors, and other high-demand applications. This article delves into the details of taped litz wire, its construction, features, applications, and why it is the preferred choice for critical industries.
What is Taped Litz Wire?
Taped Litz Wire refers to litz wire wrapped with high-quality insulating tapes like Mylar, PI, or PTFE, designed to meet specific performance and durability requirements. It retains the core features of litz wire, such as reducing the skin effect and proximity effect losses, while adding enhanced insulation and thermal endurance.The overlapping tape layers ensure excellent breakdown voltage resistance and superior mechanical properties, making it ideal for high-frequency and high-voltage applications.

| Overlapping Rate | Available in 50%, 67%, or 75% overlap configurations for varying insulation requirements. |
| Strand Design | Includes up to 385 strands with diameters ranging from 0.020mm to 0.60mm. |
| Tape Options | Materials like Mylar, PI (Polyimide), and PTFE films provide flexibility and durability. |
| Thermal Classes | Options available for 155°C, 180°C, 200°C, and beyond. |
How is Taped Litz Wire Constructed?
The construction of taped litz wire involves wrapping individually insulated strands of enameled copper wire with a specific type of tape. The degree of overlap ensures the desired insulation and mechanical strength. This process follows stringent manufacturing standards to ensure consistent quality and performance.
Insulation and Tape Materials
- Mylar Tape: Offers excellent electrical insulation and thermal resistance.
- PI Film (Polyimide): Provides superior radiation resistance, making it suitable for applications requiring high mechanical stress.
- PTFE Film: Ensures high flexibility and resistance to extreme environments.
The wire is constructed with care to meet precise requirements, such as thermal endurance, defined creepage distances, and resistance to flexing and mechanical stress.
Key Features of Taped Litz Wire
1. High Insulation Strength
The layered tape insulation provides superior protection against voltage breakdown and ensures stable performance in high voltage applications. The use of advanced materials like PI and PTFE enhances the wire’s durability under harsh conditions.
2. High Thermal Performance
With thermal ratings of up to 155°C and beyond, taped litz wire is ideal for applications requiring consistent performance under extreme heat. The insulation materials ensure minimal thermal degradation over time.
3. Resistance to Radiation
The use of PI tapes in certain configurations makes taped litz wire suitable for applications requiring high resistance to radiation, such as aerospace and medical equipment.
Applications of Taped Litz Wire
1. Transformers with High Interlayer Discharge Voltage
Taped litz wire is widely used in transformers where high interlayer discharge voltage and superior thermal performance are critical. Its ability to handle high breakdown voltage ensures reliable operation in high-stress environments.
2. Motors and Generators
In applications requiring high thermal resistance and durability, such as motors and generators, taped litz wire excels due to its robust construction and superior insulation.
3. High-Frequency Applications
Taped high-frequency litz wire minimizes energy losses caused by the skin effect and proximity effect, making it ideal for SMPS (Switched-Mode Power Supplies), inverters, and other high-frequency applications.
Why Use Taped Litz Wire?
1. How Does Taped Litz Wire Reduce Skin Effect?
The skin effect occurs when high-frequency currents tend to flow on the surface of a conductor, increasing resistance and energy losses. By using multiple individually insulated strands, taped litz wire effectively distributes the current, reducing these losses.
2. What Makes Taped Litz Wire Suitable for High-Voltage Applications?
The tape insulation provides an additional layer of protection, ensuring the wire can handle voltage resistance in demanding applications. This makes it a preferred choice for transformers and motors where high reliability is required.
