1. Conductivity: Lub conductivity ntawm txhuas alloy yog 61.5% ntawm cov feem ntau siv benchmark khoom tooj liab IACS, thiab tam sim no nqa peev xwm yog 79% tooj liab, uas yog superior rau tus qauv rau ntshiab txhuas.
2. Creep kuj: Cov khoom siv alloy thiab cov txheej txheem annealing ntawm aluminium alloy conductor txo qhov nyiam ntawm tus neeg xyuas pib mus rau "ceep" nyob rau hauv tshav kub thiab siab. Piv nrog rau cov ntshiab txhuas, cov creep kuj yog nce los ntawm 300%, tsis txhob muaj teeb meem so los ntawm cov dej txias los yog creep.
3. Tensile zog thiab elongation: Piv rau cov ntshiab txhuas conductors, aluminium alloy conductors tau zoo heev tensile lub zog vim qhov sib ntxiv ntawm cov khoom xyaw tshwj xeeb thiab siv cov txheej txheem tshwj xeeb, thiab elongation tau nce mus rau 30%, ua rau lawv muaj kev nyab xeeb thiab txhim khu kev qha siv.
4. Thermal expansion coefficient: Thermal expansion coefficient yog siv los xam qhov seem hloov ntawm cov khoom thaum kub hloov.The thermal expansion coefficient ntawm aluminium alloy yog piv rau cov tooj liab, thiab aluminium connectors tau ntseeg tau siv rau tooj liab thiab txhuas. conductors tau ntau xyoo. Feem ntau ntawm cov khoom siv hluav taws xob siv niaj hnub no yog ua los ntawm txhuas, uas yog tshwj xeeb tshaj yog haum rau aluminium alloy.Yog li ntawd, kev nthuav dav thiab kev cog lus ntawm aluminium alloy conductors thiab connectors yog zoo ib yam.
5. Muaj zog tus kheej hnyav bearing muaj peev xwm. Aluminium alloy txhim kho lub zog tensile ntawm ntshiab txhuas, thiab aluminium alloy cables tuaj yeem txhawb nqa tus kheej qhov hnyav ntawm 4000 meters ntev, thaum tooj liab cables tsuas yog txhawb nqa 2750 meters.Qhov zoo dua no tshwj xeeb tshaj yog nyob rau hauv kev xaim ntawm cov vaj tse loj xws li cov chaw ua kis las.
6. Anti-corrosion kev ua tau zoo: Lub hauv paus los tiv thaiv corrosion kev ua tau zoo ntawm txhuas yog tsim los ntawm cov txheej nyias nyias tab sis muaj zog oxide txheej ntawm cov txhuas nto thaum nws los rau hauv kev sib cuag nrog huab cua. Cov txheej txheej oxide no tshwj xeeb tshaj yog tiv taus ntau hom kev xeb.Qhov sib ntxiv ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb rau cov alloys tuaj yeem txhim kho cov kev tiv thaiv corrosion ntawm txhuas, tshwj xeeb tshaj yog electrochemical corrosion.Qhov muaj peev xwm ntawm txhuas los tiv thaiv ib puag ncig hnyav ua rau nws siv dav hauv cov neeg siv khoom. ntawm cov cables hauv cov tais, nrog rau ntau cov khoom lag luam thiab cov thawv ntim khoom.Qhov tshwm sim ntawm corrosion feem ntau yog cuam tshuam nrog kev sib txuas ntawm cov hlau sib txawv hauv qhov chaw ntub dej, thiab cov kev tiv thaiv zoo tuaj yeem siv los tiv thaiv corrosion, xws li kev siv cov roj nplua nyeem, antioxidants, thiab tiv thaiv coatings.Alkaline av thiab tej yam acidic av ib puag ncig muaj ib tug siab corrosivity rau txhuas, yog li txhuas conductors uas ncaj faus yuav tsum tau tiv thaiv corrosion siv insulating txheej los yog molded sheaths.In sulfur-muaj ib puag ncig, xws li railway tunnels thiab lwm qhov chaw zoo sib xws, kev tiv thaiv corrosion ntawm aluminium alloys zoo dua li ntawm tooj liab.
7. Flexibility Aluminium alloy muaj cov khoom zoo heev bending, thiab nws qhov tshwj xeeb alloy formulation thiab kev siv tshuab zoo heev txhim kho nws qhov yooj.Aluminium alloy yog 30% hloov tau ntau dua li tooj liab thiab muaj qhov elasticity qis dua tooj liab.Qhov dabtsi yog khoov vojvoog ntawm cov khoom siv tooj liab yog {{ 2}} zaug ntawm txoj kab uas hla sab nraud, thaum lub vojvoog dabtsi yog khoov ntawm aluminium alloy cables tsuas yog 7 npaug ntawm txoj kab uas hla sab nraud, ua rau nws yooj yim rau kev txuas cov terminals.
8. Cov yam ntxwv ntawm armored Feem ntau ntawm cov armored cables feem ntau siv nyob rau hauv Suav teb siv steel daim kab xev armor, uas muaj kev nyab xeeb tsawg. Thaum raug kev puas tsuaj rau sab nraud, nws qhov kev tiv thaiv tsis zoo, yooj yim ua rau tawg, thiab qhov hnyav hnyav, ua rau cov nqi siab heev. Tsis tas li ntawd, nws cov corrosion kuj tsis zoo thiab nws cov kev pab cuam lub neej tsis ntev.Txawm li cas los xij, cov hlau saw armored cable tsim los ntawm peb raws li tus qauv American siv aluminium alloy daim kab xev saw armor. Cov qauv saw ntawm cov khaubncaws sab nraud povtseg kom ntseeg tau tias lub cable tuaj yeem tiv taus kev puas tsuaj sab nraud. Txawm tias thaum lub cable raug lub zog loj thiab cuam tshuam, nws tsis yooj yim punctured, txhim kho kev nyab xeeb kev ua tau zoo.Tam sim no, cov qauv armor cais cov cable los ntawm lub ntiaj teb sab nraud. Txawm tias thaum muaj hluav taws kub, txheej armor pab txhim kho cov nplaim hluav taws thiab tiv thaiv hluav taws ntawm cov kab hluav taws xob, txo qhov kev pheej hmoo ntawm hluav taws.Piv nrog steel daim kab xev armor, aluminium alloy daim kab xev armor qauv yog lub teeb yuag, yooj yim rau nteg, tuaj yeem ntsia tau yam tsis muaj lub tais, thiab tuaj yeem txo cov nqi teeb tsa los ntawm 20% mus rau 40%.
9. Compact yam ntxwv Xav txog tsuas yog lub ntim conductivity, aluminium alloy yog inferior rau tooj liab. Txawm li cas los xij, tus neeg xyuas pib peb tsim tsis tau tsuas yog txhim kho cov khoom siv, tab sis kuj ua rau muaj kev cuam tshuam loj hauv cov txheej txheem. Peb tau txais ib qho kev sib cog lus tsis sib haum xeeb kom ua tiav qhov kev sib cog lus ntawm 0.93, thaum lub compact factor ntawm lub zoo li tus hlau yuav ncav cuag 0.95, uas yog thawj nyob rau hauv Tuam Tshoj.Los ntawm lub siab tshaj plaws txwv ntawm compact, nws tuaj yeem ua rau qhov tsis txaus ntawm aluminium alloy nyob rau hauv ntim conductivity, ua rau stranded conductor core zoo li ib tug khoom neeg xyuas pib, ho txo lub sab nraud txoj kab uas hla ntawm cov tub ntxhais thiab kev txhim kho cov conductivity. Sab nraud txoj kab uas hla ntawm tus neeg xyuas pib tsuas yog 10% loj dua li ntawm tooj liab cable nyob rau hauv tib lub peev xwm nqa tam sim no.
