Cov khoom no yog siv rau hauv cov hlau txhuas thiab cov hlau tub ntxhais hlau rau cov kab hluav taws xob saum toj kawg nkaus.
Tus qauv no yog raws li pawg neeg saib xyuas hluav taws xob thoob ntiaj teb (IEC61089-1991), Cov xov hlau sib npaug concentric overheah hluav taws xob stranded conductors Muab los ntawm IEC.
Cov hlau cored txhuas strand, hlau core muaj zog dua, txhuas muaj conductivity siab dua (cov coefficient tsis kam me dua), thiab qhov hnyav tshwj xeeb me dua. ACSR ua ke cov txiaj ntsig no thiab tsim nyog rau kev xa hluav taws xob nrog lub zog siab, hluav taws xob siab thiab kev ncua deb ntev; Txawm li cas los xij, cov hlau strand tsuas yog muaj zog siab thiab tsis haum rau kev xa hluav taws xob.
Cov Lus Qhia Tshwj Xeeb Cov lus qhia tshwj xeeb tau qhia los ntawm ntu ib txwm muaj. Cov lus qhia tshwj xeeb ntawm cov xov hlau txhuas yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm lub rooj 2 Cov lus qhia tshwj xeeb ntawm cov neeg hlau txhuas uas muaj hlau txhawb thiab cov neeg hlau txhuas uas tiv thaiv xeb uas muaj hlau txhawb yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm lub rooj 4.
