Lub luag haujlwm tseem ceeb ntawm unshielded nruab nrab voltage cable yog xa hluav taws xob hluav taws xob thiab cov teeb liab, thaum muab kev rwb thaiv tsev yooj yim thiab kev tiv thaiv kev ua haujlwm. Hom kab no feem ntau yog siv nyob rau hauv qhov voltage ntawm 1000V thiab 30kV thiab yog dav siv nyob rau hauv ntau yam kev lag luam thiab kev lag luam ib puag ncig.
Cov qauv ntawm unshielded nruab nrab voltage cables yog kuj yooj yim, feem ntau yog tsim los ntawm conductors, rwb thaiv tsev txheej, thiab sheaths. Tus neeg xyuas pib yog lub hauv paus ntawm lub cable, lub luag haujlwm rau kev xa tawm tam sim no; Cov txheej rwb thaiv tsev yog qhwv ib ncig ntawm tus neeg xyuas pib txhawm rau tiv thaiv tam sim no to thiab luv luv Circuit Court; Lub sheath muab kev tiv thaiv lub cev ntxiv los tiv thaiv kev puas tsuaj sab nraud. Cov qauv no ua rau kev teeb tsa thiab kev saib xyuas ntawm cov kab hluav taws xob nruab nrab uas tsis muaj hluav taws xob tau yooj yim thiab siv tau zoo.
Unshielded nruab nrab voltage cables yog haum rau ntau yam ib puag ncig thiab kev siv, suav nrog tab sis tsis txwv rau cov kab ntau lawm, cov tsev lag luam, thaj chaw nyob, thiab lwm yam. Lawv tuaj yeem tiv taus qee yam kev ntxhov siab, muaj qee yam huab cua tsis kam thiab kev ntseeg siab, thiab tuaj yeem hloov mus rau qhov chaw ua haujlwm sib txawv.
