Steel-cored aluminium stranded hlau yog dav siv nyob rau hauv overhead kis tau tus mob thiab tis kab ntawm ntau theem voltage, tshwj xeeb tshaj yog haum rau scenarios nrog ntev spans thiab siab mechanical zog yuav tsum tau, xws li complex terrains xws li roob roob, hav, thiab dej hla, raws li zoo raws li lub nroog fais fab mov thiab high -voltage projection.
Nws cov ntawv thov tseem ceeb suav nrog:
High-voltage thiab ultra-high-voltage kis kab: Nyob rau hauv cov kab kis tau tus mob nrog voltage theem ntawm 220kV thiab siab dua, steel-cored aluminium stranded hlau yog dav siv vim nws lub zog siab thiab siab tam sim no{5}} nqa peev. Nws tuaj yeem txhawb nqa nws tus kheej qhov hnyav thiab kev thauj khoom sab nraud (xws li cua thiab dej khov) thaum lub sijhawm ntev - erection nrug, thaum ua kom muaj zog sib kis tau zoo.
Ntev - ncua sij hawm thiab hnyav icing thaj chaw: Vim lub zog tensile muaj zog muab los ntawm cov tub ntxhais hlau, tus neeg xyuas no tshwj xeeb yog tsim rau ntev - ncua kev ua haujlwm (xws li hla tus Dej Yangtze lossis hav txwv yeem) thiab thaj chaw uas muaj dej khov hnyav, txo cov pej thuam, txo qis, thiab txhim kho kab kev ruaj ntseg.
Hauv Nroog thiab Densely Populated Area Power Distribution Networks: Hauv kev hloov kho lub zog hauv nroog, steel-cored aluminium stranded hlau yog siv nyob rau hauv 10kV thiab hauv qab kab sib faib, tshwj xeeb tshaj yog nyob rau hauv cheeb tsam uas muaj kev nyab xeeb nyob deb thiab qhov chaw txwv. Nws cov qauv txhim khu kev qha, kev saib xyuas yooj yim, thiab kev yoog raws rau cov neeg nyob hauv qhov siab - nce lub tsev ib puag ncig ua rau nws zoo tagnrho rau cov ntawv thov no.
Ntug hiav txwv dej thiab Corrosive Environments: Los ntawm kev siv aluminium-clad steel cores los yog anti-corrosion coatings, steel-cored aluminium stranded hlau tuaj yeem ua haujlwm ruaj khov hauv thaj chaw ntug dej hiav txwv, thaj chaw ntsev ntsev, thiab thaj chaw muaj kuab paug, nthuav tawm cov kev tiv thaiv zoo heev thiab ua kom nws lub neej ntev.
Lub zog-Txuag thiab Muaj Peev Xwm-Kev nce qib: piv rau cov neeg siv khoom ib txwm muaj, qee yam tshiab ntawm cov hlau-cored aluminium stranded hlau (xws li nthuav txoj kab uas hla thiab tshav kub- resistant aluminium alloy hom) tuaj yeem ua rau muaj peev xwm nqa tam sim no thiab txo corona poob. Lawv tau siv rau kev txhim kho kev muaj peev xwm ntawm cov kab laus, ua tiav siab - kev txhim kho kev ua tau zoo nrog kev nqis peev tsawg.
