Ioyile itanki ye-transformer idityaniswe ngamacangci entsimbi anamandla aphezulu kwaye yahlulwe yangamacandelo aphezulu nasezantsi. I-Shell-type transformers ine-coil evalwe ngokupheleleyo nge-insulating material kwaye ijikelezwe yi-wire cores, ngoko akukho loyiko lomonakalo ngenxa yeempembelelo zangaphandle, kwaye akukho mfuneko yokubonelela ngendawo yokukhusela. Ngokusekwe koku, kukho indawo encinci yendibano phakathi kombindi wentsimbi ye-transformer yohlobo lweqokobhe kunye nodonga lwangaphakathi lweoyile. itanki. Itanki yeoli ihambelana ngokusondeleyo kunye nentsimbi yentsimbi kunye nama-windings. Itanki yeoli iyisakhiwo esidityanisiweyo ngokupheleleyo ngaphandle kweebholiti, ehluke kakhulu kwiinguqu zendabuko. Umzimba ufakwe kwi-tank ye-fuel, ezaliswe ngeoli ye-transformer.
