Magnet Wire for all applications
Flat wire
Engineered for superior space efficiency and optimized for high power density, flat wire is ideal for compact and high-performance applications like electric motors and transformers.
Round wire
A versatile and reliable solution, round wire combines excellent conductivity with mechanical robustness, ensuring consistent performance across various industries and applications.
Hollow wire
Designed for advanced cooling solutions, hollow wire integrates fluid channels for thermal management in high-power applications, enhancing efficiency and reliability.
Concentric coating
Tretau’s concentric coating ensures uniform insulation thickness around the wire, providing optimal electrical insulation and reducing the risk of localized breakdowns.
Eccentric coating
Specially developed for applications requiring tailored insulation, eccentric coating provides variable thickness to meet specific design and performance needs.
Technical specifications
Tretau’s magnet wire is designed to meet the specific demands of our customers. With fully customizable solutions, we produce magnet wire featuring a monolayer coating that offers best-in-class dielectric properties, exceptional aging performance, a bending radius of ≤ 1.0 mm (for rectangular wire), and a record-breaking adhesion stripping force of ≥ 2.0 N/mm (PEEK).
Tretau’s DryCycle coating technology enables the delivery of technopolymers-based (PEEK, PAEK, PEKK, PFA, PPS, PPSU) magnet wire tailored for high heat and voltage thresholds.
