Fecral alloy xov hlau rau cov hlua hlau feem ntau yog ua los ntawm cov hlau tsis muaj hlau nrog cov ntsiab lus carbon ntawm 0.4 txog 0.95%.Lub zog siab heev ntawm cov hlua hlau ua rau cov hlua hlau los txhawb lub zog tensile loj thiab khiav hla sheaves nrog me me diameters.

Nyob rau hauv lub thiaj li hu ua cross lay strands, cov xov hlau ntawm cov txheej txheem sib txawv.Nyob rau hauv feem ntau siv parallel lay strands, nteg ntev ntawm tag nrho cov hlau khaubncaws sab nraud povtseg yog sib npaug zos thiab cov nyob ntawm tej ob txheej superimposed yog parallel, uas ua rau linear sib cuag.Cov xaim ntawm txheej txheej yog txhawb los ntawm ob lub xov hlau ntawm cov txheej sab hauv.Cov xov hlau no yog cov neeg nyob sib ze nrog rau tag nrho qhov ntev ntawm txoj hlua.Parallel lay strands yog ua nyob rau hauv ib qho kev ua haujlwm.Qhov kev ua siab ntev ntawm cov hlua hlua nrog cov hlua zoo li no ib txwm muaj ntau dua li ntawm cov (tseem siv tau) nrog ntoo khaub lig lay strands.Parallel nteg strands nrog ob txheej hlau muaj cov kev tsim kho Filler, Seale lossis Warrington.

Nyob rau hauv txoj cai, kauv ropes yog puag ncig strands raws li lawv muaj kev sib dhos ntawm cov khaubncaws sab nraud povtseg ntawm cov xov hlau nteg helically hla ib qho chaw nrog tsawg kawg ib txheej ntawm cov xov hlau raug nteg nyob rau hauv qhov opposite kev taw qhia rau cov txheej txheej.Kauv ropes tuaj yeem ua tau qhov loj me ntawm txoj hauv kev uas lawv tsis tig uas txhais tau hais tias nyob rau hauv qhov nro ntawm txoj hlua torque yog zero.Txoj hlua qhib kauv tsuas muaj cov xov hlau puag ncig xwb.Cov hlua khi ib nrab thiab cov hlua khi tag nrho cov hlua khi ib txwm muaj qhov chaw ua los ntawm cov xov hlau puag ncig.Cov hlua khi hlua khi muaj ib lossis ntau txheej txheej ntawm cov xov hlau.Lawv muaj qhov zoo dua tias lawv cov kev tsim kho tiv thaiv kev nkag mus ntawm av thiab dej kom ntau dua thiab nws kuj tiv thaiv lawv los ntawm kev poob ntawm cov roj nplua nyeem.Tsis tas li ntawd, lawv muaj ib qho txiaj ntsig tseem ceeb ntxiv vim qhov kawg ntawm cov hlau tawg sab nraud tsis tuaj yeem tawm ntawm txoj hlua yog tias nws muaj qhov loj me.
Stranded hlau yog tsim los ntawm ib tug xov tooj ntawm cov xov hlau me me bundled los yog qhwv ua ke los tsim ib tug loj conductor.Stranded hlau yog hloov tau yooj yim dua li cov khoom siv hlau ntawm tib qhov chaw hla ntu.Stranded hlau yog siv thaum muaj zog tiv thaiv hlau qaug zog.Cov xwm txheej zoo li no suav nrog kev sib txuas ntawm cov rooj sib tham hauv Circuit Court hauv ntau cov khoom siv hluav taws xob-circuit-board, qhov twg cov khoom siv hlau yuav ua rau muaj kev ntxhov siab ntau dhau los ntawm kev txav mus los thaum sib dhos lossis kev pabcuam;AC kab hlua rau cov khoom siv;suab paj nruagkabs;computer naskabs;vuam electrode cables;tswj cov kab txuas txuas cov tshuab txav;mining tshuab cables;trailing tshuab cables;thiab ntau lwm tus.
