Aluminium cable, zoo li lwm yam, muaj ntau tus yam ntxwv. Cov npe no suav nrog cov kev txwv xws li cov khoom siv thiab ntu ntu ntawm cov tub ntxhais, cov khoom siv rau rwb thaiv tsev thiab cov xov tooj ntawm cov tub ntxhais.

thawj tus yam ntxwv

Yog li, thawj qhov ntsuas yog cov khoom tseem ceeb. Nyob rau hauv lub neej txhua hnub, tib neeg feem ntau yog siv peb lub ntsiab cables: tooj liab, txhuas thiab txhuas-tooj liab. Yog tias peb tham txog aluminium cable, peb tuaj yeem hais txog qhov zoo xws li tus nqi qis, lub teeb yuag, hluav taws xob zoo, hloov hluav taws xob zoo, tshuaj tiv thaiv.

Txawm li cas los xij, muaj qee qhov tsis zoo ntawm cov xaim no:

• Cov khoom siv me me yooj yim. Yog tias koj khoov ib qho txhuas hlau ob peb zaug hauv tib qhov chaw, nws yuav tawg. Nws ua raws los ntawm qhov no hais tias kev ua haujlwm ntawm hom kab no tsuas yog siv tau rau hauv qhov chaw ruaj khov tsis muaj qhov ntse ntse, tig, thiab lwm yam.
• Oxidation ntawm kev sib cuag nrog huab cua. Thaum huab cua cuam tshuam nrog cov hlau no, aluminium oxide tshwm. Qhov no yog ib zaj duab xis refractory dub heev uas npog lub hauv paus. Tag nrho cov teeb meem yog tias cov oxide yogua kom tiav dielectric. Vim li no, hauv qhov chaw uas cov yeeb yaj kiab tau tsim, cov hluav taws xob tam sim no tsis dhau.
• Aluminium yog suav tias yog tus neeg xyuas pib zoo, tab sis qhov no tsuas yog cov khoom siv ntshiab, uas yog, tsis muaj impurities. Tam sim no qhov no nyuaj heev kom ua tiav.

Second parameter - section

Txoj kev hla ntawm ib qho txhuas cable yog ib yam tseem ceeb uas siv tau rau txhua yam ntawm tus neeg xyuas pib. Yog tias peb tham txog cov xov hlau feem ntau, ces lawv cov hlaws tuaj yeem nyob hauv thaj tsam ntawm 0.3 txog 800 mm². Txawm li cas los xij, nws yuav tsum tau hais tias nws tsis pom zoo kom siv cov xov hlau zoo li no hauv lub neej txhua hnub. Feem ntau yog los ntawm 0.35 txog 16mm². Tsis tshua muaj, tab sis tseem, 25 mm cables siv ^2.

Txhawm rau txiav txim siab seb ntu twg yuav tsum tau muaj nyob rau hauv ib qho kev sib txuas, nws yuav tsum tau ua raws li lub zog tam sim no thiab qhov hluav taws xob uas yuav nyob hauv lub network. Kev vam khom ntawm cov kev txwv no yooj yim heev. Qhov tuab ntawm qhov hla ntawm cable, qhov ntau dua qhov conductivity nws muaj. Lwm qhov me me tab sis tseem ceeb yam ntxwv ntawm lub cable nrog aluminium conductors yog lawv tus lej. Nyob ntawm qhov ntsuas no, qhov hloov pauv ntawm cov hlau tag nrho yuav hloov pauv. Qhov kev vam khom ntawm tus yam ntxwv no yog raws li hauv qab no - ntau tus neeg xyuas pib hauv ib ntu, qhov hloov pauv ntawm cov hlau yuav ntau dua.

Insulation Nyob

Yog tias koj xaiv tus yam ntxwv tseem ceeb tshaj plaws ntawm aluminium cables, nws yuav yog cov khoom siv insulating. Nws yog cov khoom no uas txiav txim siab seb qhov zoo ntawm cov hlau yuav muaj li cas. Nyob ntawm cov rwb thaiv tsev, muajxws li hom cables: armored, tshav kub-resistant, waterproof, nrog siab tiv thaiv, thiab lwm yam. Txij li thaum hluav taws xob tam sim no yog ib tug tiag tiag txaus ntshai rau tib neeg lub neej, qhov teeb meem ntawm cable rwb thaiv tsev yog qhov tseem ceeb tshaj plaws ntawm nws txoj haujlwm. Txawm li cas los xij, nws yuav tsum tau hais ntawm no tias kev rwb thaiv tsev yog xav tau tsis yog los tiv thaiv tus neeg xwb, tab sis kuj los tiv thaiv tus neeg xyuas pib nws tus kheej. Qhov no yog qhov zoo tshaj plaws pom yog tias muaj hlua khi.

Kev sib tw rwb thaiv tsev thiab lub zog dielectric

Yog tias peb tham txog lub luag haujlwm tseem ceeb ntawm kev rwb thaiv tsev, lawv suav nrog cov hauv qab no: kev tiv thaiv tawm tsam, nrog rau kev tiv thaiv hluav taws xob, kev tiv thaiv hluav taws xob thiab hluav taws xob ntawm lub cable nws tus kheej, qhia txog cov khoom siv hluav taws xob. Nws yog ib qho tsim nyog sau cia ntawm no tias muaj ntau yam khoom siv rau rwb thaiv tsev, nrog rau hom rwb thaiv tsev. Nws yuav siv sij hawm ntau npaum li cas los txiav txim siab txhua hom, thiab tsis tas li ntawd, nws tsis muaj kev nkag siab. Nws yog qhov zoo tshaj plaws los txiav txim siab txog cov uas muaj feem xyuam rau hauv tsev.

Tam sim no, muaj ob hom tseem ceeb. Thawj yog TPZh - ib tug conductive core, raws li zoo raws li ib tug sheath npog cov tub ntxhais los ntawm sab nraud. Lub ntsiab parameter uas cov khoom siv rau rwb thaiv tsev yog xaiv yog lub zog hluav taws xob. Qhov kev ntsuas no tuaj yeem piav qhia raws li hauv qab no: qhov no yog tus nqi ntawm lub zog tam sim no, uas yuav txaus kom tawg los ntawm cov txheej txheem insulating nrog lub thickness ntawm 1 hli. Nws yuav tsum tau muab sau tseg tias tag nrho cov cables uas tau siv nyob rau hauv domestic tej yam kev mob muaj ib tug loj hluav taws xob lub zog, thiab yog li ntawd lub tawg ntawm hluav taws xob tam sim no yog ua tau tsuas yog nyob rau hauv cov ntaub ntawv ntawm mechanical puas.cable rwb thaiv tsev nws tus kheej.

Heat resistance

Tus yam ntxwv thib ob ntawm cov khoom siv insulating siv los npog cov txhuas cable yog cov cua sov ua haujlwm. Txhua yam yog qhov yooj yim heev ntawm no: qhov loj dua tus nqi no, qhov ntau dua qhov kub ntawm cov khoom siv tuaj yeem tiv taus yam tsis poob nws cov khoom. Qhov no yog qhov tseem ceeb heev, txij li txhua tus paub tias thaum hluav taws xob dhau mus, tus neeg xyuas pib ua kom sov. Yog tias tus nqi tsis loj txaus, cov khoom siv insulating yuav yaj. Qhov no kuj suav nrog xws li cov khoom zoo ntawm cov hlau xws li tiv thaiv Frost thiab mechanical zog. Lawm, qhov muaj zog thiab ntau dua tsim kua muag-resistant cov rwb thaiv tsev, qhov zoo dua.

Ib qho ntawm cov khoom siv rwb thaiv tsev niaj hnub no yog polyvinyl chloride (PVC). Cov khoom no qhia nws qhov zoo tshaj plaws thaum tiv thaiv alkalis thiab lwm cov kua qaub. Qhov tsis zoo ntawm cov khoom siv no suav nrog qhov tseeb tias nws muaj qhov tsis kam tiv thaiv Frost - tsuas yog mus txog -20 degrees Celsius.

fais fab cable nrog aluminium conductors

Cov kab no feem ntau yog siv hauv cov kab hluav taws xob siab. Nws yog ib qho tsim nyog yuav tsum tau sau tseg ntawm no tias ntawm qhov kub siab tshaj qhov tus nqi ntawm qhov muaj peev xwm nqa lub peev xwm ntawm xws li cable tsis hloov. Txawm li cas los xij, nrog kev thim rov qab, uas yog, nrog rau qhov txo qis hauv qhov kub thiab txias, qhov kev tawm mus kuj yuav txo qis. Lub zog aluminium cable yog qhov dav heev vim tias nws muaj tus nqi qis. Txawm li cas los xij, nws kuj muaj me mehnyav txawm nrog loj qhov ntev. Nws yog cov txiaj ntsig zoo no uas paub qhov txawv ntawm lub cable nrog cov tub ntxhais aluminium los ntawm ib lub cable nrog tooj liab.

Txawm li cas los xij tus nqi qis tsis yog ib txwm zoo. Cov lus tawm tswv yim los ntawm cov neeg yuav khoom thiab cov neeg siv hluav taws xob yog qhov tsis sib haum xeeb ntawm qhov qhab nia no. Yog lawm, aluminium cables pheej yig dua, tab sis lawv qhov kev tiv thaiv yog yuav luag ib thiab ib nrab zaus ntau dua li tooj liab, piv txwv li. Hauv lwm lo lus, qhov tsis zoo yog tias nrog tib seem hla, aluminium cable hla ib thiab ib nrab zaus tsawg dua tam sim no thiab tib lub sijhawm heats li. Yuav kom daws tau qhov teeb meem no, koj yuav tsum tau yuav ib lub cable nrog ib ntu tuab.

Aluminium Armored Cable

Ib armored cable txawv ntawm tus so hauv qhov ntawd, ntxiv rau kev rwb thaiv tsev, nws kuj muaj txheej txheej hlau. Lub xub ntiag ntawm ib txheej hlau ntxiv zoo heev ua rau lub neej kev pab cuam ntawm xws li cable, thiab tus neeg xyuas pib tau txais kev tiv thaiv ntau dua los ntawm kev puas tsuaj.

Feem ntau, galvanized daim kab xev yog siv los ua txheej hlau, uas yog qhov txhab ntawm cov txheej txheem ntawm cov pa rwb thaiv tsev. Qhov tsis zoo, tau kawg, yog qhov yuav luag tiav ntawm kev hloov pauv ntawm cable, uas dhau los ua pom ntau dua nyob rau hauv cov ntaub ntawv ntawm txhuas tus neeg xyuas pib, uas pib muaj qhov yooj yim me ntsis.
