Overhead Kab

Vim hais tias cov conductors siv los ua tam sim no tau teeb tsa rau ntawm cov ncej nrog insulators thiab fittings, lawv hu ua cov kab hluav taws xob thiab cov hluav taws xob siv hluav taws xob. Cov kab hluav taws xob feem ntau yog tsim los ntawm cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov ncej thiab cov yees thiab lawv cov hauv paus, kev tiv thaiv hluav taws xob thiab cov khoom siv hauv av, thiab lwm yam. Lub luag haujlwm tseem ceeb ntawm cov xaim hluav taws xob yog ua hluav taws xob tam sim no; nws yog qhov tseem ceeb ntawm lub voj voog. Thaum ua hluav taws xob tam sim no, cov insulators yuav tsum tau ua kom peb theem insulated ntawm ib leeg thiab hauv av. Lub pej thuam yog siv los txhim kho cov conductors kom muaj ib qho kev ncua deb ntawm cov conductors thiab hauv av nrog rau ntawm peb theem. Fittings yog cov khoom siv hlau ntsia rau ntawm tus ncej thiab cov yees, siv los txuas cov xov hlau, insulators, thiab lwm yam. Lub luag haujlwm tseem ceeb ntawm tus pas nrig yog tiv thaiv tus neeg xyuas pib thiab tiv thaiv kom tsis txhob raug hluav taws xob ncaj qha.
