33kV high voltage post porcelain insulator 57-2 ANSI kirasi chiyero

Tsanangudzo Pfupi

High voltage line rod insulator inoshandiswa sekudzivirira uye inotsigira conductor mune yakakwirira voltage transmission uye mutsara wekugovera.Chigadzirwa chacho hachina kuputsika chimiro uye chine zvakanakira chepamusoro mechanical simba, yakasimba insulation kuita uye yakanaka kusvibisa kuramba.Iyo insulator ine zvakanakira kushanda kwakachengeteka uye kwakavimbika, kugadzirisa kuri nyore, hupenyu hurefu hwebasa uye mutengo wakaderera wemutsara.
