Advanatages of anti-frequency converter surge insulated magnet wire have heat resistance, mechanical property, chemical characteristic, electrical characteristic, reliability etc., as with it is exhausted The related requirement characteristic of edge, in addition to higher partial discharge inception voltage, also requires insulating properties excellent under high temperature, also have thermal aging resistance property excellent under high temperature.

Anti-frequency converter surge insulated wire is used for electric/electronic, specially high frequency printed base plate；Or frequency converter relevant device, such as high speed Electrical equipment coil of conversion element, inverter motor, transformer etc. etc., The insulated wire for enamel-covered wire to be used as magnetic wire (magnet wire), which is required that low-k and high-fire resistance are also required while high-insulativity.

Enamel paint insulation resin lamination body, with anti-frequency converter surge insulated wire and electric/electronic with the enamel paint insulation resin lamination body and conductor, the enamel paint insulation resin lamination body has foamed zones and at least one surface of foamed zones without foamed zones, and it is shaped to tabular or tubular, wherein, foamed zones are to make the bubble-free layer of not bubbles in two face sides of the bubble-free layer have to be made up of the bubble layer that separated foam is formed, the thickness of bubble-free layer is more than the thickness of the spaced walls between separated foam, and 5%~60% of the thickness for foamed zones, the at least bubble layer of foamed zones is formed by thermosetting resin.
