Traditional transformer ntxhia roj muaj teeb meem ntawm qhov qis qis (kwv yees li 160 degree) thiab ib puag ncig muaj kuab paug. Cov nroj tsuag -raws li ib puag ncig tus phooj ywg insulating roj (natural ester) siv los ntawm Pufeike Electric muaj peb qhov zoo: 1) Kev nyab xeeb siab: Flash point Ntau dua los yog sib npaug li 310 degree, txawm tias cov dej xau tshwm sim, nws tsis yooj yim rau ntes hluav taws, ua tau raws li cov kev xav tau ntawm cov chaw muaj neeg coob coob xws li siab - nce vaj tse thiab subways; 2) Kev tiv thaiv ib puag ncig: Biodegradable (degradation tus nqi ntau dua lossis sib npaug li 95%), zam cov av / dej paug, raws li EU RoHS cov lus qhia; 3) Lub neej ua haujlwm ntev: Kev tiv thaiv oxidation zoo heev, kev hloov pauv ntawm cov roj insulating txuas ntxiv mus rau 15 xyoo, txo cov sijhawm txij nkawm piv nrog cov roj ntxhia (8 xyoo). Tam sim no, cov thev naus laus zis no tau siv rau Pufeike's 10kV-110kV series transformers, pab cov neeg siv khoom ua tiav "ntsuab hluav taws xob faib" hloov khoom dua tshiab.
