Unshielded nruab nrab voltage cablehais txog qhov nruab nrab voltage cable tsis muaj neeg xyuas pib shielding txheej thiab rwb thaiv tsev shielding txheej. Hom kab no feem ntau muaj ib lossis ntau dua tooj liab lossis aluminium conductors, rwb thaiv tsev txheej, sheaths, thiab lwm yam khoom siv, thiab tsim nyog rau kev xa hluav taws xob nruab nrab voltage. Cov qauv ntawm unshielded nruab nrab voltage cables yog kuj yooj yim, tsis muaj ntxiv shielding khaubncaws sab nraud povtseg, yog li lawv cov txheej txheem tsim thiab cov nqi kuj tsawg.
Cov yam ntxwv ntawm unshielded nruab nrab voltage cable muaj xws li:
Cov qauv yooj yim: Vim tias tsis muaj cov txheej txheem tiv thaiv, cov qauv ntawm cov cable yog qhov yooj yim, txo qhov nyuaj ntawm cov txheej txheem tsim khoom.
Tus nqi qis: Qhov tsis muaj txheej thaiv thaiv ua rau qis dua tag nrho cov nqi tsim khoom cable.
Txwv tsis pub siv: Vim tsis muaj cov txheej thaiv thaiv, cov kab no tsim nyog rau cov ntawv thov uas tsis xav tau hluav taws xob ua haujlwm siab, xws li qee qhov hluav taws xob qis lossis cov hom phiaj tshwj xeeb.
Daim ntawv thov scenarios ntawm unshielded nruab nrab voltage cable mas suav nrog:
Kev faib hluav taws xob tsawg: Hauv qee qhov kev faib hluav taws xob tsawg, vim qhov tsis tshua muaj hluav taws xob thiab tam sim no, tsis tas yuav tsum muaj cov txheej thaiv thaiv ntxiv los txhim kho hluav taws xob xa hluav taws xob lossis txhim kho hluav taws xob.
Daim ntawv thov kev lag luam tshwj xeeb: Hauv qee cov ntawv thov kev lag luam nrog kev tswj hwm tus nqi nruj, cov kab hluav taws xob tsis muaj hluav taws xob tsis muaj hluav taws xob tau txais yuav vim lawv cov nqi qis dua.
Txoj hauv kev ib ntus lossis tsis tseem ceeb: Hauv qee txoj kev tsis tseem ceeb lossis ib ntus, siv cov kab hluav taws xob nruab nrab uas tsis muaj kev tiv thaiv tuaj yeem txo cov nqi pib nqis peev.
