Insulation ntchito osiyanasiyana mica chubu

Mica chubu nthawi zambiri amagwiritsa mafuta kapena gasi ngati sing’anga insulating, ndipo kawirikawiri amapangidwa thiransifoma bushings kapena dera breaker bushings, ndipo nthawi zambiri amagwiritsidwa ntchito voteji pansi 35 kV. Mkati mwake pakati pa kondakitala wa insulating chubu ndi manja a porcelain amadzazidwa ndi mafuta osinthira ma radial insulation. Mphamvu yamagetsi ikadutsa 35 kV, woyendetsa amakutidwa ndi chubu kapena chingwe kuti alimbikitse kutchinjiriza. Amagwiritsidwa ntchito makamaka pa ma ultra-high voltage transformers ndi ma circuit breakers.

Mica chubu ndi chinthu chokhala ndi resistivity mkulu ndi otsika madutsidwe. Nthawi zambiri amagwiritsidwa ntchito kuyika insulate waposachedwa komanso kutentha. Zida zotchingira zingagwiritsidwe ntchito kupatula ma conductor amoyo kapena ma conductor a kuthekera kosiyanasiyana, kuti magetsi aziyenda mbali ina. Panthawi imodzimodziyo, imathandizanso kuti pakhale kutentha, kuziziritsa, kuthandizira, kukonza, kuzimitsa kwa arc, kupititsa patsogolo kuthekera kwa gradient, chinyezi-proof, mildew-proof ndi conductor chitetezo.
