Polyimide Film Mica Tape Insulated Wire is a high-performance magnet wire designed for electrical equipment operating under extreme thermal, electrical, and environmental conditions.
The insulation system is based on a polyimide film reinforced mica tape structure, integrating the excellent dielectric and fire resistance of mica with the mechanical strength and flexibility of polyimide film.
This advanced composite insulation provides exceptional long-term reliability for critical applications where conventional organic insulation systems reach their limits.
