Aluminium alloy cables tsis tau siv rau lub sijhawm ntev hauv peb lub tebchaws, tab sis twb muaj cov xwm txheej uas qhia tau hais tias muaj kev phom sij loj heev thiab muaj kev pheej hmoo ntawm kev siv cov aluminium alloy cables hauv nroog, factories thiab mines.Ob qhov xwm txheej hauv qab no thiab yim yam ua rau muaj kev pheej hmoo ntawm kev sib tsoo ntawm aluminium alloy cables tau tham txog.
Case 1
Aluminium alloy cables tau siv rau hauv cov khoom siv hauv cov nroj tsuag steel.Ob qhov hluav taws kub tau tshwm sim hauv ib xyoos, ua rau muaj kev kaw ib nrab lub hlis thiab kev lag luam ncaj qha los ntawm 200 lab yuan.
Qhov no yog ib tug cable choj uas tau kho tom qab hluav taws kub.Cov kab hluav taws kub tseem tshwm sim.
Case ob
Aluminium alloy cables yog siv nyob rau hauv lub teeb pom kev zoo tis system ntawm ib lub nroog nyob rau hauv Hunan xeev.Tsis pub dhau ib xyoos tom qab kev teeb tsa, muaj zog corrosion ntawm aluminium alloy cables tshwm sim, ua rau muaj kev puas tsuaj ntawm cov pob qij txha thiab cov neeg xyuas pib, thiab lub zog tsis ua haujlwm ntawm cov kab.
Los ntawm ob qhov xwm txheej no, peb tuaj yeem pom tias qhov loj-loj nrov ntawm aluminium alloy cable hauv cov nroog, cov chaw tsim khoom thiab cov mines hauv Suav teb tau tso cov kev phom sij zais cia rau cov nroog, cov chaw tsim khoom thiab cov mines.Cov neeg siv tsis muaj kev nkag siab txog cov yam ntxwv ntawm aluminium alloy cable, thiab yog li raug kev txom nyem loj heev.Yog tias cov neeg siv nkag siab txog cov yam ntxwv ntawm aluminium alloy cable hauv kev tiv thaiv hluav taws kev ntseeg tau thiab kev tiv thaiv ua ntej, lawv yuav raug kev puas tsuaj loj.Kev sib deev, xws li kev poob yuav zam tau ua ntej.
Raws li cov yam ntxwv ntawm aluminium alloy cables, aluminium alloy cables muaj qhov tsis xws luag hauv kev tiv thaiv hluav taws thiab tiv thaiv corrosion.Nws yog qhia nyob rau hauv yim yam nram qab no:
1. Corrosion tsis kam, 8000 Series Aluminium alloy yog qis dua li cov aluminium alloy zoo tib yam
GB / T19292.2-2003 Standard Table 1 Note 4 hais tias qhov corrosion kuj ntawm aluminium alloy yog phem dua li cov zoo tib yam aluminium alloy thiab phem dua li tooj liab, vim hais tias cov txhuas alloy cables muaj magnesium, tooj liab, zinc thiab hlau ntsiab, yog li ntawd lawv yog nquag mus rau hauv zos corrosion xws li kev nyuaj siab corrosion cracking, txheej corrosion thiab intergranular corrosion.Ntxiv mus, 8000 Series Aluminium alloy belongs rau cov qauv corrosion-nrhiav, thiab aluminium alloy cables yooj yim rau corroded.Ntxiv cov txheej txheem kev kho cua sov, nws yooj yim ua rau lub cev tsis sib xws, uas yooj yim dua rau corroded dua aluminium cable.Tam sim no, aluminium alloys siv nyob rau hauv peb lub teb chaws yog 8000 txhuas alloy series.
2. Kub tsis kam ntawm aluminium alloy yog qhov sib txawv ntawm cov tooj liab.
Lub melting point ntawm tooj liab yog 1080 thiab ntawm txhuas thiab txhuas alloys yog 660 yog li tooj liab conductor yog ib qho kev xaiv zoo dua rau refractory cables.Tam sim no qee cov tuam txhab lag luam aluminium alloy tau thov kom muaj peev xwm tsim cov khoom siv hluav taws xob aluminium alloy cables thiab dhau lub teb chaws cov qauv ntsuas, tab sis tsis muaj qhov sib txawv ntawm aluminium alloy cables thiab aluminium cables hauv qhov kev hwm no.Yog hais tias qhov kub thiab txias siab tshaj qhov melting point ntawm aluminium alloy thiab aluminium cable nyob rau hauv qhov hluav taws kub qhov chaw (saum toj no), tsis muaj teeb meem dab tsi rwb thaiv tsev ntsuas cov cables coj, cov cables yuav yaj nyob rau hauv ib tug luv luv lub sij hawm thiab poob nws conductive muaj nuj nqi.Yog li ntawd, aluminium thiab aluminium alloys yuav tsum tsis txhob siv los ua refractory cable conductors lossis nyob rau hauv cov neeg nyob hauv nroog loj, cov tsev, factories thiab mines.
3. Lub thermal expansion coefficient ntawm aluminium alloy yog ntau dua li ntawm tooj liab, thiab ntawm AA8030 aluminium alloy tseem siab dua li ntawm cov zoo tib yam aluminium alloy.
Nws tuaj yeem pom los ntawm lub rooj hais tias thermal expansion coefficient ntawm txhuas yog ntau dua li ntawm tooj liab.Aluminium alloys AA1000 thiab AA1350 tau txhim kho me ntsis, thaum AA8030 tseem siab dua li ntawm txhuas.High thermal expansion coefficient yuav ua rau kev sib cuag tsis zoo thiab lub voj voog vicious ntawm cov conductors tom qab thermal expansion thiab contraction.Txawm li cas los xij, ib txwm muaj lub ncov thiab hav hauv lub hwj chim, uas yuav ua rau muaj kev sim loj rau kev ua haujlwm ntawm lub cable.
4. Aluminium alloy tsis daws qhov teeb meem ntawm aluminium oxidation
Aluminium alloys los yog aluminium alloys raug rau cov cua yuav sai sai tsim ib qho nyuaj, kev sib raug zoo tab sis tsis yooj yim zaj duab xis nrog ib tug tuab ntawm txog 10 nm, uas muaj siab resistivity.Nws hardness thiab bonding quab yuam ua rau nws nyuaj rau tsim conductive hu.Qhov no yog vim li cas yog vim li cas cov oxide txheej ntawm lub npoo ntawm txhuas thiab txhuas alloys yuav tsum tau muab tshem tawm ua ntej installation.Copper nto kuj oxidizes, tab sis oxide txheej yog mos thiab yooj yim rau tawg mus rau hauv semiconductors, tsim hlau-hlau sib cuag.
5. Aluminium alloy cables tau txhim kho kev ntxhov siab thiab nkag siab, tab sis deb tsawg dua tooj liab cables.
Cov khoom nkag ntawm aluminium alloy tuaj yeem txhim kho los ntawm kev ntxiv cov ntsiab lus tshwj xeeb rau hauv aluminium alloy, tab sis qib ntawm kev txhim kho yog tsawg heev piv nrog aluminium alloy, thiab tseem muaj qhov sib txawv loj piv nrog tooj liab.Txawm hais tias aluminium alloy cable tuaj yeem txhim kho qhov kev nkag siab zoo yog ze rau kev siv tshuab, thev naus laus zis thiab kev tswj hwm qib ntawm txhua lub lag luam.Qhov kev tsis paub tseeb no nws tus kheej yog qhov pheej hmoo.Yog tias tsis muaj kev tswj hwm nruj ntawm cov cuab yeej paub tab, kev txhim kho ntawm kev nkag siab ntawm aluminium alloy cable tsis tuaj yeem lav.
6. Aluminium alloy cable tsis daws qhov teeb meem kev ntseeg siab ntawm kev sib txuas ntawm txhuas
Muaj tsib yam cuam tshuam rau kev ntseeg siab ntawm aluminium pob qij txha.Aluminium alloys tsuas yog txhim kho ntawm ib qho teeb meem, tab sis tsis tau daws qhov teeb meem ntawm cov pob qij txha ntawm txhuas.
Muaj tsib qhov teeb meem hauv kev sib txuas ntawm aluminium alloy.Kev ntxhov siab thiab kev ntxhov siab ntawm 8000 Series Aluminium alloy tau raug txhim kho nkaus xwb, tab sis tsis muaj kev txhim kho hauv lwm yam.Yog li ntawd, qhov teeb meem kev sib txuas tseem yuav yog qhov teeb meem loj cuam tshuam rau qhov zoo ntawm aluminium alloy.Aluminium alloy kuj yog ib hom txhuas thiab tsis yog cov khoom siv tshiab.Yog tias qhov sib txawv ntawm cov khoom siv tseem ceeb ntawm txhuas thiab tooj liab tsis raug daws, aluminium alloy tsis tuaj yeem hloov tooj liab.
7. Qhov tsis zoo creep kuj ntawm domestic aluminium alloys vim tsis zoo tswj (alloy muaj pes tsawg leeg)
Tom qab POWERTECH xeem nyob rau hauv Canada, muaj pes tsawg leeg ntawm domestic aluminium alloy tsis ruaj khov.Qhov sib txawv ntawm Si cov ntsiab lus nyob rau hauv North American aluminium alloy cable yog tsawg dua 5%, thaum lub sij hawm ntawm domestic aluminium alloy yog 68%, thiab Si yog ib qho tseem ceeb ntawm cov khoom uas cuam tshuam rau creep zog.Ntawd yog hais tias, kev nkag siab ntawm kev siv hluav taws xob hauv tsev aluminium alloy tseem tsis tau tsim los ntawm cov cuab yeej paub tab.
8. Aluminium alloy cable sib koom ua ke thev naus laus zis yog txoj hauv kev yooj yim thiab yooj yim kom tawm hauv qhov tsis zoo.
Aluminium alloy cable pob qij txha muaj peb txheej txheem ntau dua li tooj liab cable sib txuas.Kev tshem tawm zoo ntawm oxide txheej thiab txheej ntawm cov tshuaj tua kab mob antioxidant yog qhov tseem ceeb.Cov qib kev tsim kho hauv tsev, cov kev xav tau zoo tsis sib xws, tawm hauv qhov kev phom sij zais.Tsis tas li ntawd, vim tsis muaj kev cai lij choj kev lav phib xaub hauv Suav teb, qhov kev poob siab kawg hauv kev coj ua yog qhov xav tau los ntawm cov neeg siv lawv tus kheej.
Ntxiv nrog rau cov xwm txheej saum toj no, aluminium alloy cable kuj tsis muaj kev sib koom ua ke ntawm kev txiav tawm khiav, qhov kev sib txuas ntawm lub davhlau ya nyob twg tsis dhau, lub capacitive tam sim no nce, qhov kev ncua deb ntawm aluminium alloy cable yuav nqaim los yog tsis txaus los txhawb vim qhov nce kev hla ntu, kev tsim kho nyuaj yog tshwm sim los ntawm kev nce ntawm cable hla ntu, qhov sib txuam ntawm qhov chaw cable trench, kev ceev ceev ntawm kev tu thiab kev pheej hmoo ntawm tus nqi.Cov teeb meem kev tshaj lij, xws li kev nce nqi ntawm lub neej voj voog thiab qhov tsis muaj cov qauv tsim rau cov neeg tsim qauv ua raws li, xws li kev tuav tsis raug lossis tsis txhob txwm tsis quav ntsej txog ib qho ntawm lawv, txaus ua rau cov neeg siv raug kev txom nyem hnyav thiab tsis tuaj yeem poob thiab raug xwm txheej.
