Qhov Sib Txawv ntawm Tooj Liab Cable thiab Aluminium Cable

Thaum xaiv cov xov hlau uas siv tooj liab thiab cov xov hlau uas siv txhuas yog qhov tseem ceeb heev, ob hom xov hlau no muaj lawv qhov zoo thiab qhov tsis zoo, thiab kev nkag siab txog lawv qhov sib txawv tuaj yeem pab koj txiav txim siab tau zoo.

Cov xov tooj liab tseem ceeb yog paub txog lawv cov hluav taws xob zoo heev thiab tiv taus xeb. Lawv kuj yooj ywm dua thiab yooj yim siv dua li cov xov tooj txhuas tseem ceeb. Qhov no ua rau lawv yog qhov kev xaiv nrov rau kev tsim hluav taws xob hauv tsev thiab kev lag luam. Txawm li cas los xij, cov xov tooj liab tseem ceeb feem ntau kim dua li cov xov tooj txhuas tseem ceeb, uas yuav yog qhov tsis zoo rau qee tus neeg siv.

Ntawm qhov tod tes, cov xov hlau txhuas tseem ceeb yog sib dua thiab pheej yig dua li cov xov hlau tooj liab tseem ceeb. Vim lawv qhov hnyav sib dua thiab tus nqi qis, lawv kuj zoo dua rau kev xa hluav taws xob mus deb. Txawm li cas los xij, cov xov hlau txhuas tseem ceeb muaj cov hluav taws xob qis dua thiab yooj yim rau xeb, uas tuaj yeem cuam tshuam rau lawv cov kev ua tau zoo thiab lub neej ua haujlwm.

Ib qho ntawm qhov sib txawv tseem ceeb ntawm cov xov tooj liab thiab cov xov hlau txhuas yog lawv qhov ampacity, uas yog hais txog qhov siab tshaj plaws ntawm cov hluav taws xob uas cov xov hlau tuaj yeem nqa tau. Cov xov hlau tooj liab muaj qhov ampacity siab dua li cov xov hlau txhuas ntawm tib qhov loj me, ua rau nws tsim nyog dua rau cov ntawv thov uas xav tau cov khoom siv hluav taws xob ntau dua.

Lwm yam tseem ceeb uas yuav tsum xav txog yog qhov thermal expansion thiab contraction ntawm lub cable. Cov cables txhuas muaj cov coefficient ntawm expansion ntau dua li cov cables tooj liab, uas txhais tau tias lawv yuav xoob dua li lub sijhawm. Yog tias tsis tuav kom zoo, nws tuaj yeem ua rau muaj kev phom sij rau kev nyab xeeb thiab teeb meem hluav taws xob.

Hauv kev xaus lus, qhov kev xaiv ntawm cov xov tooj liab thiab cov xov tooj txhuas yog nyob ntawm qhov xav tau tshwj xeeb ntawm kev teeb tsa hluav taws xob. Txawm hais tias cov xov tooj liab muaj kev coj ua hluav taws xob zoo thiab ruaj khov, cov xov tooj txhuas yog qhov kev xaiv pheej yig rau kev xa hluav taws xob mus deb. Kev nkag siab txog qhov sib txawv ntawm ob hom xov tooj tuaj yeem pab cov neeg siv txiav txim siab raws li lawv cov kev xav tau tshwj xeeb thiab kev txwv nyiaj txiag.
