Kub
Qhov kub thiab txias tuaj yeem ua rau cov ntaub ntawv rwb thaiv tsev tsis zoo nyob rau lub sijhawm, ua rau txo lub zog dielectric thiab ua tsis tiav.
Cov ntsiab lus noo noo
Cov dej noo yog ib qho ntawm cov yeeb ncuab tseem ceeb ntawm cov ntawv rwb thaiv tsev. Cov dej noo siab tuaj yeem txo cov dielectric zog thiab ua rau kev laus.
Kev laus thiab degradation
Nrog lub sijhawm, txawm tias cov ntawv rwb thaiv tsev zoo tshaj plaws yuav degrade. Kev soj ntsuam tsis tu ncua thiab kev saib xyuas yog tsim nyog los xyuas kom meej tias cov transformers txuas ntxiv ua haujlwm kom raug.
