Engineered to withstand harsh operational stresses, extreme temperatures, and structural mechanical challenges.
Fiberpolyesterimide (EIW) coated wire represents the pinnacle of high-thermal performance winding materials. Engineered using a polyesterimide base coat with a modified polyamideimide (AIW) topcoat, these conductors operate reliably under continuous temperatures up to 200°C and peak surges exceeding 220°C.
As modern electrification shifts toward high-voltage systems (specifically the 800V EV battery architectures and high-density distribution transformers), selecting the correct magnet wire coating is critical. Traditional coatings fail under the thermal and mechanical stresses of high-speed automation, making Fiberpolyesterimide Coated Wire the new industry baseline.
