Cov xov hluav taws xob nruab nrab yog siv rau kev xa hluav taws xob los ntawm ib qho chaw mus rau lwm qhov. Cov xov no feem ntau siv rau hauv cov chaw lag luam, cov chaw tsim hluav taws xob, thiab lwm yam kev siv uas xav tau hluav taws xob siab.
Muaj ntau hom xov hluav taws xob nruab nrab, xws li XLPE (cross-linked polyethylene) insulated cables, EPR (ethylene propylene roj hmab) insulated cables, thiab PILC (paper insulated lead covered) cables.
Cov xov hluav taws xob XLPE insulated yog hom xov hluav taws xob nruab nrab uas siv ntau tshaj plaws. Lawv paub txog lawv cov khoom siv hluav taws xob zoo heev, kev ruaj khov thermal siab, thiab tiv taus dej noo thiab tshuaj lom neeg. Cov xov hluav taws xob EPR insulated kuj nrov vim lawv qhov yooj ywm, tiv taus cua sov thiab txias, thiab cov khoom siv hluav taws xob zoo. Cov xov hluav taws xob PILC, ntawm qhov tod tes, yog cov thev naus laus zis qub dua thiab tsis tshua siv niaj hnub no vim lawv tus nqi siab dua thiab kev ua haujlwm qis dua piv rau cov xov hluav taws xob XLPE thiab EPR.
Thaum xaiv cov xov hluav taws xob nruab nrab voltage, nws yog ib qho tseem ceeb uas yuav tsum xav txog cov yam xws li qhov ntsuas voltage, lub peev xwm nqa tam sim no, cov khoom siv rwb thaiv tsev, qhov loj me thiab hom conductor, thiab lub peev xwm ntawm cable los tiv taus cov yam ntxwv ib puag ncig xws li kub, noo noo, thiab tshuaj lom neeg. Nws tseem yog ib qho tseem ceeb kom ntseeg tau tias cov cable ua raws li cov qauv kev lag luam thiab cov cai.
Kev teeb tsa thiab kev saib xyuas cov xov hluav taws xob nruab nrab kom zoo yog qhov tseem ceeb heev rau kev ua haujlwm kom muaj kev nyab xeeb thiab txhim khu kev qha. Qhov no suav nrog kev xa cov xov hluav taws xob, kev txiav, thiab kev sib txuas kom zoo, nrog rau kev tshuaj xyuas thiab kev sim tsis tu ncua kom pom cov teeb meem uas yuav tshwm sim thaum ntxov.
