Amafutha tank we-transformer ashiselwe ngamapuleti ensimbi aqinile futhi ahlukaniswe izingxenye ezingaphezulu nezingezansi. Ama-Shell-type transformers anamakhoyili avaliwe ngokuphelele nge-insulating material futhi azungezwe ama-wire cores, ngakho-ke akukho ukwesaba ukulimala ngenxa yamathonya angaphandle, futhi asikho isidingo sokuhlinzeka ngendawo yokuvikela. Ngokusekelwe kulokhu, kunesikhala esincane sokuhlangana phakathi komgogodla wensimbi we-transformer yohlobo lwegobolondo kanye nodonga lwangaphakathi lwamafutha. tank. Ithangi likawoyela lihambisana eduze nengqikithi yensimbi namawindi. Ithangi lamafutha liyisakhiwo esishiselwe ngokuphelele ngaphandle kwama-bolts, ahluke kakhulu kuma-transformers endabuko. Umzimba ufakwe ethangini likaphethiloli, eligcwele uwoyela we-transformer.
