Lub winding yog ib feem ntawm lub transformer, uas yog mob nrog ib daim ntawv-pob insulated ca hlau los yog round hlau.

Tus neeg xyuas pib ntawm lub transformer coil yog ua los ntawm tooj liab hlau nrog cov duab plaub thiab siab conductivity, thiab sab nrauv yog qhwv nrog ob txheej ntawm kraft ntawv rau rwb thaiv tsev lub hom phiaj. Rau insulating pads ntawm tib cov khoom, tus naj npawb ntawm cov xov tooj ntawm tooj liab nyob ntawm qhov ua haujlwm voltage, yog li cov coil cov ntsiab lus muaj txaus insulating zog ntawm cov khaubncaws sab nraud povtseg. Siv cov kua nplaum rau ntawm txheej sab nraud ntawm daim ntawv insulating, txhua txheej qhwv yog glued ua ke los tsim ib lub voj voog nruj. Txhawm rau txo qis qhov poob tam sim no, kab hla hla yog ua nyob rau ntawm qhov chaw ua ntej ntawm tus neeg xyuas pib. Lub kauj ntawm lub plhaub-hom transformer yog tsau vertically. Txhawm rau tiv thaiv kev tsis sib haum xeeb, ib daim ntoo ntoo yog muab tso rau ntawm lub kauj thiab cov tub ntxhais hlau. Txhua qhov kawg ntawm lub kauj yog kho los ntawm cov tub ntxhais hlau thiab cov roj tank. Lub zog sab nraud yog muab faib rau hauv ib cheeb tsam loj, uas zoo heev txhim kho cov neeg kho tshuab lub zog. .
