Dab tsi yog qhov hluav taws xob hluav taws xob hluav taws xob?
Lub ntsiab lus ntawm overhead bar cable
Tsis muaj cov ntaub thaiv npog, nws tau ncaj qha ntsia sab nraum zoov ntawm cov ncej fais fab thiab cov yees, feem ntau yog siv rau siab -voltage/ultra{{1}high voltage overhead transmission kab.

Tej yam kev thov scenarios |
|
ACSR |
Aluminium Conductor Steel Reinforced |
Sab nrauv aluminium strand (conductive) + central steel core (muaj peev xwm tiv taus qhov nro) |
High voltage kis tau tus mob mainline, feem ntau mainstream nyob rau hauv domestic fais fab tuag thiab txawv teb chaws kis tau tus mob thiab tis; 10kV ~ 500kV nyiaj siv ua haujlwm hluav taws xob |
|
UAAC |
Txhuas Aluminium Alloy Conductor |
Txhua yam ua los ntawm aluminium alloy ib lub xov hlau twisted tsis muaj steel core |
Nruab nrab thiab tsis tshua muaj hluav taws xob faib kab, ntug hiav txwv corrosive ib puag ncig, teeb pom kev zoo; 10 ~ 110 kV |
|
AAC |
Txhua tus neeg xyuas pib |
Ntshiab txhuas hlau ib leeg twisted raws li ib tug tag nrho, tsis muaj reinforcing core |
Tsis tshua muaj hluav taws xob luv luv kev faib tawm thiab cov kab hluav taws xob nyob deb nroog; Tsawg voltage Tsawg dua lossis sib npaug li 35kV, cov kab me me |
|
GS/GW |
Galvanized Steel Strand |
Tag nrho cov kub -dip galvanized steel hlau yog sib tw ua ke thiab tsis yog -conductive (tsis tshua muaj siv rau kev nqa tam sim no) |
Kev tiv thaiv xob laim hauv av, ntauwd nyob hlau, thiab kho qhov muag cable (OPGW pob txha) tsis xa hluav taws xob hluav taws xob |
ACSR steel cored aluminium stranded hlau
Aluminium: Conductive (Aluminium muaj cov conductivity zoo heev thiab yog lub teeb yuag)
Cov tub ntxhais hlau: tsuas yog muaj peev xwm tiv taus txhua yam tensile quab yuam
Qhov zoo thiab qhov tsis zoo: Qhov zoo tshaj plaws ntawm kev sib npaug ntawm kev coj ua thiab lub zog siv tshuab, tus nqi siab tshaj -kev ua tau zoo, thiab qhov tsis zoo ntawm lub ntiaj teb cov phiaj xwm hluav taws xob: electrochemical corrosion muaj nyob rau ntawm cov hlau aluminium tiv tauj nto, thiab lub neej kev pab cuam luv luv nyob rau hauv ib puag ncig corrosive heev ntawm ntug dej hiav txwv.
Voltage siv: 10kV, 35kV, 110kV, 220kV, 500kV siab -voltage overhead main kab
AAC tag nrho aluminium stranded hlau
Tag nrho cov txhuas hlau tsis muaj steel core
Qhov zoo: Tus nqi qis;
Disadvantages: Tsawg tensile lub zog, tsis tuaj yeem ntsia tau rau ntawm qhov loj. Haum rau qhov tsis tshua muaj hluav taws xob luv luv nyob deb nroog cov phiaj xwm hluav taws xob, nroog 10kV ceg kab, thiab cov kab me me
Tsis haum rau thaj chaw roob thiab loj - kis tau tus mob hla tus dej
AAAC aluminium alloy stranded hlau
Kev siv tag nrho ntawm aluminium magnesium silicon alloy hlau, tsis muaj steel core piv rau cov ntshiab txhuas (AAC): siab zog tensile, muaj zog corrosion kuj piv rau ACSR: me me qhov hnyav, tsis muaj steel txhuas electrochemical corrosion.
Core scenario: ntug hiav txwv dej thiab thaj chaw muaj kev lag luam nrog corrosion hnyav
Galvanized Steel Strand
Yuav luag tsis siv los ua cov xaim nqa tam sim no! Tsis muaj peev xwm xa hluav taws xob, tsis tshua muaj hluav taws xob conductivity, cia siab rau lub zog hlau rau kev ntxhov siab
Lub Hom Phiaj: ① Nyiaj siv ua haujlwm hauv av xaim (xov hluav taws xob tiv thaiv kab hluav taws xob) nyob rau sab saum toj ntawm cov xaim hluav taws xob ② Kev sib zog rub hlau rau lub zog ncej thiab hlau yees
Tshwj xeeb: OPGW fiber optic composite av xaim muaj steel strands thiab optical fibers sab hauv.
