1. Tsawg resistivity: Lub resistivity ntawm aluminium cable yog li 1.68 npaug siab dua li ntawm tooj liab hluav taws xob Cable.
2. Zoo ductility: elongation tus nqi ntawm tooj liab alloy yog 20 ~ 40%, elongation tus nqi ntawmCopper Hluav Taws Xob Cableyog ntau tshaj 30%, thiab aluminium alloy tsuas yog 18%.
3. Lub zog siab: qhov tso cai rau kev ntxhov siab ntawm chav tsev kub yog 7 ~ 28% siab dua li ntawm txhuas. Tshwj xeeb tshaj yog qhov kev ntxhov siab ntawm qhov kub thiab txias, qhov sib txawv ntawm ob yog nyob deb heev.
4. Los tiv thaiv kev qaug zog: aluminium yog yooj yim tawg los ntawm kev rov kho dua, thiab tooj liab tsis yooj yim. Nyob rau hauv cov nqe lus ntawm elasticity Performance index, tooj liab kuj yog hais txog 1.7 mus rau 1.8 lub sij hawm siab tshaj txhuas.
5. Zoo stability thiab corrosion kuj: tooj liab tub ntxhais yog resistant rau oxidation thiab corrosion, thaum txhuas core yog susceptible oxidation thiab corrosion.
6. Lub peev xwm nqa tam sim no loj: vim qhov tsis muaj zog, cov tub ntxhais tooj liab cable ntawm tib seem yog li 30% siab tshaj qhov tso cai tam sim no nqa peev xwm (qhov siab tshaj plaws tam sim no tuaj yeem hla) ntawm cov tub ntxhais aluminium cable.
7. Tsis tshua muaj hluav taws xob poob: vim qhov tsis tshua muaj hluav taws xob ntawm cov tooj liab cable, tib qhov tam sim no ntws los ntawm tib seem. Cov tooj liab cable muaj qhov me me voltage poob. Qhov sib kis tau zoo tib yam tuaj yeem ua kom muaj hluav taws xob zoo; Nyob rau hauv qhov kev tso cai ntawm qhov poob qis, qhov kev sib txuas ntawm tooj liab tuaj yeem ncav cuag qhov ntev, uas yog, qhov chaw siv hluav taws xob muaj qhov loj, uas yog qhov tsim nyog rau kev npaj network thiab txo cov naj npawb ntawm cov khoom siv hluav taws xob.
8. Tsawg cua sov: nyob rau hauv tib lub tam sim no, cov cua kub tso tawm ntawm cov tub ntxhais tooj liab cable nrog tib seem yog ntau me dua li ntawm aluminium core cable, ua rau kev ua haujlwm zoo dua.
9. Kev siv hluav taws xob tsawg: Vim qhov tsis tshua muaj zog ntawm tooj liab, piv nrog aluminium cables, lub zog poob ntawm tooj liab cables yog tsawg, uas yog pom tseeb. Qhov no yog qhov tsim nyog rau kev txhim kho cov khoom siv hluav taws xob thiab kev tiv thaiv ib puag ncig.
10. Oxidation kuj thiab corrosion kuj: lub taub hau kev twb kev txuas ntawm cov tub ntxhais tooj liab cable yog ruaj khov thiab yuav tsis ua rau raug mob vim oxidation. Cov pob qij txha tsis ruaj khov ntawm aluminium core cables feem ntau ua rau muaj kev sib tsoo vim qhov nce ntawm kev tiv thaiv thiab cua sov vim oxidation. Yog li ntawd, qhov kev huam yuaj yog ntau dua li ntawm cov tub ntxhais tooj liab cables.
11. Kev tsim kho yooj yim:
Cov tub ntxhais tooj liab muaj qhov ua tau zoo thiab qhov me me uas tuaj yeem khoov lub vojvoog, yog li nws yooj yim tig thiab yooj yim rau Pierce cov yeeb nkab;
Cov tub ntxhais tooj liab los tiv thaiv kev qaug zog, rov kho dua tsis yooj yim rau kev tawg, yog li cov xaim yog yooj yim;
Cov tub ntxhais tooj liab muaj lub zog ua haujlwm siab thiab tuaj yeem tiv taus qhov sib tsoo loj, uas ua rau muaj kev yooj yim rau kev tsim kho thiab tso, thiab tseem tsim cov kev tsim kho tshuab.
