Lub hauv paus ntsiab lus ua haujlwm ntawm steel-cored aluminium stranded hlau siv cov qauv "rigid-flexible". Cov tub ntxhais hlau sab hauv bears cov neeg kho tshuab load, thaum cov txheej aluminium strands yog lub luag hauj lwm rau hluav taws xob conduction. Qhov kev tsim qauv no ua rau lub zog siab ntawm cov hlau thiab kev ua haujlwm zoo ntawm txhuas. Ib txhij, los ntawm kev siv cov nyhuv ntawm daim tawv nqaij ntawm alternating tam sim no, qhov tam sim no tsuas yog ntws nyob rau hauv lub sab nrauv txhuas feem ntawm tus neeg xyuas pib, txo qhov cuam tshuam ntawm cov tub ntxhais hlau ntawm conductivity efficiency.
Nws lub hauv paus ntsiab lus ua haujlwm tseem ceeb tuaj yeem faib ua cov ntsiab lus hauv qab no:
Clear Structure Division of Functions
Steel Core ("Rigid"): Nyob ntawm qhov chaw ntawm tus neeg xyuas pib, nws yog tsim los ntawm galvanized steel hlau lossis siab - lub zog steel strands. Nws feem ntau dais cov neeg kho tshuab nro ntawm cov nyiaj siv ua haujlwm, xws li nws tus kheej qhov hnyav, cua thauj khoom, thiab icing, kom ntseeg tau tias tus neeg xyuas pib tsis tawg mus ntev thiab loj spans.
Aluminium Stranded Wire ("Flexible"): qhwv ib ncig ntawm cov tub ntxhais hlau, nws yog tsim los ntawm ntau cov hlua ntawm cov tawv txhuas hlau. Nws feem ntau ua haujlwm ntawm kev xa hluav taws xob hluav taws xob. Vim nws cov conductivity siab (kwv yees li 61% IACS), nws ua tau zoo txo qhov tsis kam.
Cov nyhuv ntawm daim tawv nqaij Optimizes Conductivity: Vim yog cov nyhuv ntawm daim tawv nqaij ntawm alternating tam sim no, tam sim no zoo li ntws mus rau saum npoo ntawm tus neeg xyuas pib. Hlau -cored aluminium stranded hlau siv cov yam ntxwv no, tso cov txhuas txhuas nyob rau hauv txheej txheej. Txawm hais tias cov tub ntxhais hlau sab hauv muaj cov conductivity tsis zoo, nws yuav tsis cuam tshuam rau tag nrho cov conductivity efficiency.
Synergistic Txhim Kho Cov Khoom Siv Hluav Taws Xob thiab Hluav Taws Xob: Lub xub ntiag ntawm cov tub ntxhais hlau tseem ceeb ua rau lub zog tensile ntawm tus neeg xyuas pib, ua rau nws tsim nyog rau kev hla txoj kev nyuaj xws li hav thiab dej.
Cov aluminium- clad steel core qauv kuj zam electrochemical corrosion los ntawm kev sib cuag ncaj qha ntawm cov hlau thiab txhuas, txuas rau tus neeg xyuas pib lub neej, ua rau nws tshwj xeeb tshaj yog haum rau cov chaw ntug dej hiav txwv lossis cov pa phem.
Kev khiav hauj lwm kub thiab tam sim no muaj peev xwm nqa tau zoo: Ordinary steel-cored aluminium stranded hlau tso cai rau ntev -lub sij hawm ua hauj lwm kub ntawm 70 degree, thaum tshav kub- hom resistant tuaj yeem ncav cuag 150℃. Luv-lub sij hawm ua haujlwm kub tuaj yeem tiv taus 180-230 degree, thiab qhov kev tso cai txuas mus ntxiv tam sim no muaj peev xwm nqa tau yog 1.5-2.5 npaug ntawm cov neeg siv hluav taws xob zoo tib yam ntawm tib qhov tshwj xeeb.
