Introduction

ETFE-insulated Litz wire is a highly specialized wiring solution designed for advanced electrical applications, particularly those operating in high-frequency environments. This Litz wire has an internal single-wire diameter of 0.1 mm and is constructed from 250 strands of enameled copper wire. This sophisticated construction enhances flexibility and reduces skin-effect losses, making it ideal for high-frequency applications.

The conductors are insulated with ETFE (ethylene tetrafluoroethylene), a high-performance polymer known for its excellent heat and chemical resistance. ETFE is rated for temperatures up to 155°C, ensuring the conductors perform effectively in a variety of harsh conditions. The thinner walls of the winding wires allow for efficient use of space, making them particularly suitable for primary applications in multi-conductor configurations.

Standard

·IEC 60317-23

·NEMA MW 77-C

·customized according to customer requirements.

Advantages

One of the key advantages of ETFE insulation is its superior bending properties compared to other fluoropolymers. This property enables tighter bends without compromising the integrity of the wire, making it ideal for high-frequency interconnects. ETFE also offers excellent water and chemical resistance, further enhancing the wire's durability and longevity in harsh environments.

The combination of these properties makes ETFE insulated litz wire particularly suitable for high-frequency transformer winding applications where reliability and performance are critical. Its lightweight and flexible design, coupled with its excellent electrical performance, makes it the first choice for engineers and designers seeking efficient high-frequency wiring solutions.

We support small batch customization, the minimum order quantity is 1000 meters.
