I-F-grade epoxy resin prepreg yenziwe nge-polyester film polyester fiber non-woven soft composite material futhi ifakwe ne-epoxy resin engashi.Ithatha indawo yendwangu engenisiwe engamelani nokushisa epoxy engeyona eyelukiweyo engafakwanga pre-impregnated resin non-woven fabric (HTEPP), inezinto ezinhle kakhulu zikagesi, ukumelana nokushisa, ukungalawuleki komlilo, isikhathi eside sokugcina endaweni yokushisa yasekamelweni, ingasetshenziswa njenge-transformer yohlobo olomile oluphansi. -i-voltage coil interlayer insulation kanye ne-F-class Motor slot insulation kanye nokufakwa kwesigaba.
