Roj-immersed transformers siv roj ua lub hauv paus rwb thaiv tsev thiab cua txias nruab nrab, siv txoj kev xws li roj-immersed tus kheej-txias, roj-immersed cua txias, roj-immersed dej txias, thiab yuam roj ncig. Cov khoom tseem ceeb ntawm lub transformer muaj xws li cov tub ntxhais, windings, tank, conservator, breather, tawg- cov yeeb nkab pov thawj (siab nyem valve), radiator, insulating bushings, kais changer, roj relay, ntsuas kub, thiab roj purifier.
Vim lub sij hawm ntev - immersion ntawm silicon steel nplooj ntawv nyob rau hauv lub transformer, roj permeates cov txheej, thiab cov elasticity ntawm transformer roj muab ib tug buffering nyhuv, ua rau cov suab nrov qis. Txawm li cas los xij, qhov hloov hluav taws xob hloov hluav taws xob nyob hauv lub tank, thiab nws qhov kev sib cuag thaum hloov hluav taws xob tsis pom los ntawm sab nraud. Yog tias kev sib cuag tau ploj, lub Circuit Court qhib; kev sib cuag tsis zoo tuaj yeem yooj yim hlawv tawm qhov hloov pauv nyob rau hauv kev thauj khoom ntau dhau.
