Khoom Taw Qhia:
Raws li insulating thiab txhawb tus neeg xyuas pib nyob rau hauv HV kis tau tus mob & tis kab, post insulators tau muab faib ua kab post porcelain insulator, cross arm porcelain insulator thiab long rod suspension insulator thiab lwm yam. Lawv muaj cov yam ntxwv ntawm tsis muaj puncture, siab mechanical zog, zoo heev rwb thaiv tsev thiab anti- pa phem. Hom insulator no muaj kev nyab xeeb thiab txhim khu kev qha hauv kev ua haujlwm, yooj yim hauv kev txij nkawm, lub neej ntev hauv kev khiav thiab qis nqi.
