Description

Extruded ETFE litz wire is a specialized cabling solution designed for high-performance applications, particularly those in high-voltage environments.

This litz wire has an internal single-wire diameter of 0.21 mm and made of 7 strands twisted together. This construction enhances flexibility and reduces skin-effect losses, making it ideal for high-frequency applications.

The wires are insulated with ETFE (ethylene tetrafluoroethylene), a high-performance polymer renowned for its exceptional heat and chemical resistance. The ETFE insulation is applied using an extrusion process, ensuring a uniform and durable coating, providing superior protection against environmental factors such as moisture, chemicals, and extreme temperatures. One of ETFE's key advantages is its high dielectric strength, enabling the insulation to withstand a breakdown voltage of up to 14,000V. This makes extruded ETFE stranded wire particularly suitable for high-voltage transformers and other critical electrical equipment, ensuring reliable performance and safety.
