Qhov zoo ntawm toughened iav insulator
1. Nws muaj lub zog dielectric siab heev piv rau cov plooj (porcelain).
2. Nws kuj yog siab heev.
3. Nws muaj qis coefficient ntawm thermal expansion.
4. Nws muaj zog tensile ntau dua piv rau porcelain insulator.
5. Raws li nws yog pob tshab nyob rau hauv qhov tsis yog rhuab nyob rau hauv tshav ntuj li porcelain.
6. Cov impurities thiab huab cua npuas tuaj yeem tshawb pom tau yooj yim hauv lub iav insulator lub cev vim nws cov pob tshab.
7. Cov iav muaj lub neej ua haujlwm ntev heev vim tias cov khoom siv hluav taws xob thiab hluav taws xob ntawm iav tsis cuam tshuam los ntawm kev laus.
8. Tom qab tag nrho, iav yog pheej yig dua porcelain.
