Txheej txheem cej luam los ntawm insulators rau kev tsheb ciav hlau fais fab
Cov ntxig hluav taws xob ntawm cov tsheb nqaj hlau traction zog muab faib rau cov pas nrig hom kab hluav taws xob rau cov catenary, kev rho tawm hom insulators, cov hlau txuas ntxiv hom kab hluav taws xob, txuas hluav taws xob rau cov ntu tiv thaiv, thiab lwm yam. Raws li cov khoom siv, muaj cov tshuaj thaiv zoo (feem ntau yog cov roj hmab insulators roj hmab), cov nplaim hluavtaws insulators, tempered iav insulators thiab hais txog.
Cov ntsuas hluav taws xob thoob ntiaj teb, xws li cov hlaws hluav taws xob thiab cov ntxig hluav taws xob, tsim tawm raws li lub teb chaws tus qauv (GB) thiab cov qauv kev lag luam (feem ntau DL qauv rau cov tshuab fais fab). Cov.
Cim npe nrov: rho tawm hluavtaws hluavtaws tso rau cov tsheb ciav hlau, Tuam Tshoj, tuam ntxhab, cov muag khoom, lub Hoobkas, lag luam wholesale, kev muag khoom
