Development of New Magnet Wire Insulation & A New Flat Cable Manufacturing Concept

摘要

Long experience in coating optical fibers with UV curable inks/resins has resulted in the development of completely new product lines. For many years now, the copper wire used in magnet wire has been insulated by applying layers of enamel to it (enamelled copper wire). Many coats of the solvent-based varnishes used for this purpose are applied in several passes and dried by evaporating the solvent. The new process developed by Medek & Schorner involves replacing conventional solvent-based varnishes with varnishes cured by UV irradiation. This process does not produce any solvent vapors, and the use of UV radiators reduces energy costs to far below the level previously required for thermal drying ovens at comparable levels of production.
