Make technique, the quality of case lid sealing member has strict requirements, if not reaching the reliable request of use, then can cause transformator
When temperature height, pasta raises, and makes insulating oil overflow；
2, it is arranged on the transformator of cold zone insulating oil liquid level after a period of time of stopping transport and declines more, Power resumption again
Shi Rongyi causes transformer safety accident；
3, the full-sealed transformer of band oil conservater structure can increase the overall dimensions of transformator, increases cost, also gives transport
Certain impact is brought with installing；
4, the full-sealed transformer of band oil conservater structure, if capsule quality is unreliable disrepair phenomenon occurs, works as transformator
Insulating oil can be caused to overflow when higher temperature runs.
