Ioyile yokukhusela i-varnish, eyaziwa ngokuba yipeyinti yokukhusela okanye i-varnish, idlala indima ekukhuseleni ubushushu, ukumelana nokufuma, ukusasazwa kobushushu, kunye nokuphilisa kwii-transformers ezisebenzisa i-frequency ephezulu.
Ngokweekhemikhali ezahlukeneyo, ii-oyile zokukhusela ubushushu okwangoku zingahlulwahlulwa zibe ziindidi ezintathu: ezisekwe kwi-polyester; udidi lwe-resin; izinto ze-siliceous. I-oyile yokukhusela ubushushu ye-polyester ilungiselelwa ikakhulu yi-condensation reaction ye-polyols kunye ne-polyacids, kwaye idla ngokuba lulwelo olungenambala okanye olukhanyayo olutyheli. Ine-voltage ephezulu yokuqhekeka kunye ne-volume resistivity, enokuthintela ngempumelelo i-current ukuba ingadluli kwaye ibonelele nge-insulation elungileyo. Inexabiso eliphezulu phakathi kweentlobo ezintathu ze-insulation oils kwaye yeyona oyile yokukhusela ubushushu esetyenziswa kakhulu kwii-transformers eziphezulu.
Nangona kunjalo, ioyile yokukhusela i-polyester ine-viscosity ephezulu, kwaye i-viscosity yayo ichaphazeleka kakhulu bubushushu. I-viscosity iyanda kakhulu kumaqondo obushushu aphantsi, nto leyo echaphazela kakhulu ukufuma kwayo kunye nefuthe lokusasaza ubushushu. Ke ngoko, xa isetyenziswa, kudla ngokuba yimfuneko ukongeza i-diluents ukunciphisa i-viscosity yeoyile yokukhusela, ukugcina ukufuma okulungileyo, kunye nokuqinisekisa ukuba i-transformer ephindaphindayo inokuntywiliselwa ngokupheleleyo ngexesha lokuntywiliselwa. Ubunzima obuthile beoyile yokukhusela i-polyester kunye ne-diluent ngokubanzi bumalunga ne-0.9, enokuvavanywa ngemitha ethile yobunzima.
Okwesibini, ioyile yokukhusela i-polyester isengozini yokubola kunye nokubola kumaqondo obushushu aphezulu, ivelisa izinto ezine-asidi kunye nodaka, oluchaphazela ukusebenza okuqhelekileyo kwemveliso kwaye lunciphise uluhlu lwayo lokusetyenziswa kwiindawo ezinobushushu obuphezulu. Ukongeza, xa kuthelekiswa neeoyile zokukhusela i-resin kunye ne-siliceous, iioyile zokukhusela i-polyester zinexabiso eliphezulu lokulahleka kwe-dielectric, oko kuthetha ukuba ukulahleka kwamandla kukhulu phantsi kwamacandelo ombane atshintshanayo kwaye kuya kuchaphazela ukusebenza kakuhle kwemveliso.
Okwangoku, ioyile yokukhusela i-polyester isetyenziswa kakhulu ekufakeni ii-windings, ezifana nee-transformers ezisebenzisa i-high-frequency, ii-motor, ii-cables, njl.njl., ezinokuphucula ukugquma, ukuhanjiswa kobushushu, kunye nokumelana nokufuma kweemveliso kunye nokwandisa ubomi bazo benkonzo. Ioyile yokukhusela i-resin yenziwe ikakhulu zii-organic polymer compounds, ezihlala zikwimo yolwelo okanye eqinileyo, kwaye zinokumelana nokuguguleka okuhle.
Iioyile zokukhusela ezisekwe kwi-resin zinokwenziwa ngokulungelelanisa umlinganiselo wezinto ezikrwada kunye neemeko zokusabela ukuze kuveliswe ulwelo lwe-resin olune-viscosity ephantsi. Ezi ziselo zinobumanzi obuhle kunye neempawu zokugquma, kwaye ngokubanzi azidingi zinyibilikisi ezongezelelweyo. Phantsi kweemeko zokufudumeza, ioyile yokukhusela esekwe kwi-resin inokuthamba okanye inyibilike. Xa kuthelekiswa neoyile yokukhusela i-polyester, ioyile yokukhusela i-resin inozinzo oluphezulu, ukusebenza ngcono kokukhusela umbane, kunye nexabiso eliphezulu. Isetyenziswa kakhulu ekugqumeni ii-transformers ezahlukeneyo, ii-terminals zombane, kunye namajoyinti. Ioyile yokukhusela i-siliceous yenziwe kakhulu zii-organic silicon compounds ezifana ne-polydimethylsiloxane. Ihlala ilulwelo olungenambala okanye olutyheli olucacileyo olune-viscosity ephantsi kakhulu kunye nokukhanya okuhle.
Xa kuthelekiswa neeoyile zokukhusela i-polyester kunye ne-resin, iioyile zokukhusela i-siliceous zinexabiso eliphantsi lokulahleka kwe-dielectric, ukulahleka kwamandla okuncinci phantsi kwamacandelo ombane atshintshanayo, kunye nokusebenza kakuhle kwemveliso. Ikwanayo nokumelana okuhle kwe-arc kunye nokumelana nokuvuza, kwaye inokugcina ukusebenza okuzinzileyo kwiindawo ezixineneyo. Ioyile yokukhusela i-siliceous ingasetyenziselwa ukuthintela i-insulation kwiindawo ezixineneyo ezifana nombane ophezulu, ubushushu obuphezulu, ukufuma okuphezulu, kunye nokubanda okukhulu, okuphucula inqanaba lokukhusela kunye nokuthembeka kokusebenza kweemveliso. Indawo yayo yokutsha ephezulu kunye neempawu zokuzicima zinika iioyile zokukhusela i-siliceous iingenelo ezibalulekileyo kukhuseleko lomlilo. Nangona kunjalo, ioyile yokukhusela i-siliceous inexabiso eliphezulu kwaye ngokubanzi ayisetyenziswa kwii-transformers eziphezulu.
