Kev xaiv ntawm cov tub ntxhais tooj liab cables thiab aluminium core cables yog qhov tseem ceeb heev thaum xaiv cov khoom siv hluav taws xob tsim nyog. Ob hom cables muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, thiab kev nkag siab txog lawv qhov sib txawv tuaj yeem pab koj txiav txim siab paub.
Copper core cables paub txog lawv cov hluav taws xob zoo heev thiab kev tiv thaiv corrosion. Lawv kuj hloov tau yooj yim dua thiab siv tau yooj yim dua li aluminium core cables. Qhov no ua rau lawv muaj kev xaiv nrov rau kev siv hluav taws xob hauv tsev thiab kev lag luam. Txawm li cas los xij, cov tub ntxhais tooj liab cables zoo li yuav kim dua li cov tub ntxhais aluminium cables, uas tej zaum yuav yog qhov tsis zoo rau qee cov neeg siv.
Ntawm qhov tod tes, aluminium core cables yog sib dua thiab pheej yig dua li cov tub ntxhais tooj liab cables. Vim lawv lub teeb nyhav thiab tus nqi qis, lawv kuj zoo dua rau kev xa hluav taws xob mus ntev. Txawm li cas los xij, aluminium core cables muaj hluav taws xob qis dua thiab muaj kev cuam tshuam ntau dua rau corrosion, uas tuaj yeem cuam tshuam rau lawv qhov kev ua tau zoo thiab kev pabcuam lub neej.
Ib qho ntawm qhov sib txawv tseem ceeb ntawm cov tooj liab thiab txhuas cables yog lawv cov ampacity, uas yog hais txog qhov siab tshaj plaws ntawm tam sim no lub cable nqa tau. Copper core cable muaj ampacity ntau dua li txhuas core cable ntawm tib qhov loj, ua rau nws tsim nyog rau cov ntawv thov uas xav tau hluav taws xob ntau dua.
Lwm qhov tseem ceeb uas yuav tau xav txog yog qhov thermal expansion thiab contraction ntawm cable. Aluminium core cables muaj cov coefficient ntau dua ntawm kev nthuav dav dua li cov tub ntxhais tooj liab cables, uas txhais tau hais tias lawv muaj feem ntau yuav xoob lub sijhawm. Yog tias tsis kho kom raug, nws tuaj yeem ua rau muaj kev nyab xeeb thiab teeb meem hluav taws xob.
Txhawm rau ua tiav, kev xaiv ntawm tooj liab tub ntxhais cable thiab aluminium core cable thaum kawg yog nyob ntawm cov kev cai tshwj xeeb ntawm kev teeb tsa hluav taws xob. Thaum tooj liab-core cables muab kev ua tau zoo thiab ua haujlwm ntev, aluminium-core cables yog qhov kev xaiv zoo rau kev xa hluav taws xob mus ntev. Kev nkag siab txog qhov sib txawv ntawm ob hom cables tuaj yeem pab cov neeg siv kev paub txog kev txiav txim siab raws li lawv cov kev xav tau tshwj xeeb thiab kev txwv nyiaj txiag.
