Transformer bushing ndi njira yotetezera yomwe imathandizira kuti kokondakita wamphamvu, wonyamula pakali pano adutse mu thanki yokhazikika ya thiransifoma. Zitsamba zomwe zimagwiritsidwa ntchito popangira ma voteji otsika a thiransifoma nthawi zambiri zimakhala zolimba zokhala ndi porcelain kapena epoxy insulator.
Chitsamba choyambira cha porcelain ndi chopangidwa ndi dothi chopanda kanthu chomwe chimalowera pabowo pakhoma kapena chitsulo, chomwe chimalola woyendetsa kudutsa pakati pake, ndikulumikiza mbali zonse ziwiri ku zida zina. Zitsamba zamtunduwu nthawi zambiri zimapangidwa ndi dothi lonyowa, lomwe limakutidwa ndi glaze.

Tili ndi mzere wathunthu wopanga kuphatikiza labu yoyesera. ndipo atha kukupatsani zinthuzo malinga ndi zomwe mukufuna.
