Iphaneli yombane edibeneyo yombane yenziwe nge-multi-layer composite ye-adhesive high-temperature ehlanganiswe nefilimu ye-polyester.Ineempawu ezintle zomatshini, iipropati zombane, i-shrinkage, i-hygroscopicity kunye nokumelana nokushisa okuthembekileyo.Isetyenziswa ikakhulu kwi-transformer eyomileyo yombane ophezulu kunye nophantsi.I-Insulation phakathi kweekhoyili, ingasetyenziselwa njenge-cylinder yokukhusela kunye ne-insulation end insulation endaweni yebhodi ye-epoxy resin, ibhodi ye-phenolic resin.
