Steel-cored aluminium stranded hlau yog tsuas yog siv nyob rau hauv siab -voltage, ntev-nruab deb, loj-span overhead kis kab. Nws kuj tau siv dav hauv kev sib txuas sib txuas, cov phiaj xwm hluav taws xob tshiab, thiab kev xa hluav taws xob hauv thaj chaw tshwj xeeb.
Tus neeg xyuas pib no muaj cov tub ntxhais hlau sab hauv thiab ib qho txhuas hlau sab nraud. Cov tub ntxhais steel muab lub zog siab, muaj peev xwm tiv taus cov khoom siv xws li cua thiab daus; aluminium txheej txheej yog lub luag hauj lwm rau conductivity. Siv lub teeb yuag thiab siab conductivity ntawm txhuas, ua ke nrog "skin effect" ntawm alternating tam sim no, nws txhim kho kev sib kis tau zoo. Yog li ntawd, nws yog qhov tshwj xeeb tshaj yog haum rau qhov ntev -kab hluav taws xob xa hluav taws xob tej yaam num uas yuav tsum tau hla hav, dej, los yog complex struts.
Cov xwm txheej tshwj xeeb ntawm daim ntawv thov muaj xws li:
High-voltage thiab ultra-high-voltage kis kab: Dav siv nyob rau hauv voltage theem ntawm 220kV thiab saum toj no, tshwj xeeb tshaj yog haum rau split conductor tsim kom muaj peev xwm kis tau tus mob thiab txo corona poob.
Kev tsim hluav taws xob hauv nroog thiab nyob deb nroog: Siv los txuas cov chaw siv hluav taws xob mus rau thaj chaw siv hluav taws xob, txhim kho cov khoom siv hluav taws xob ruaj khov thiab pab kev hloov pauv ntawm cov phiaj xwm hauv nroog thiab hauv nroog.
Kev xa tawm hluav taws xob tshiab: Kev siv hluav taws xob txuas ntxiv dua tshiab xws li cua ua liaj ua teb thiab chaw siv hluav taws xob photovoltaic siv steel -cored aluminium stranded hlau los sau thiab xa hluav taws xob mus rau hauv daim phiaj hluav taws xob loj.
Kev Thauj Khoom Siv Hluav Taws Xob: Hom tus neeg xyuas pib no feem ntau siv hauv kev tsheb ciav hlau traction fais fab mov los xyuas kom meej lub tsheb ciav hlau ruaj khov.
Heavy Icing Areas thiab Long-Span Projects: Vim nws lub zog tensile siab thiab zoo sag yam ntxwv, nws yog haum rau cov cheeb tsam uas muaj icing hnyav los yog xwm txheej yuav tsum tau ntev spans, xws li tej yaam num hla dej thiab hiav txwv.
