AS 1222.1 GSW Galvanized Steel Cable Conductor SC/GZ Messenger Wire
DOWNLOAD CATEGORY SPECIFICATIONS
Daim ntawv thov
Galvanized steel neeg xyuas pib SC / GZ yog galvanized steel hlau strands uas yog siv los txhawb nqa cov khoom siv hluav taws xob hauv kev lag luam hluav taws xob.
Yam ntxwv
galvanized txiv neej hlau yog tsim los ntawm tag nrho-tua hlau nrog cov ntsiab lus carbon ntawm 0.6% muaj UTS ntawm 1.31-1.39GPa.Nws yog galvanized los ntawm kub dip lossis electrolytic txheej txheem muab zinc txheej loj ntawm 200-260g / m2tau teev tseg hauv AS 1222.1 tus qauv.
Ntim
Kev xa khoom ntev yog txiav txim siab los ntawm kev txiav txim siab ntawm cov khoom xws li lub cev nruas qhov ntev, nruas qhov hnyav, qhov ntev thiab cov khoom siv tuav.
Kev tsim kho
Galvanized steel hlau yog stranded concentrically nrog successive khaubncaws sab nraud povtseg muaj ib tug opposite kev taw qhia ntawm nteg, txheej txheej sab xis yog sab xis.
Thaum xav tau, lub hauv paus loj dua (xov tooj hlau) suav nrog hauv tus neeg xyuas pib.Txoj kab uas hla ntawm cov hlau no yog raws li tus neeg xyuas pib tsim kev txiav txim siab thiab feem ntau yog 5% ntau dua li cov xaim nyob ib puag ncig.

Nco tseg
Cov yam ntxwv ntawm kev ua tau zoo ntawm hluav taws xob tau qhia saum toj no tsis suav cov teebmeem sib nqus rau hauv kev xav thiab yog li ntawd tsuas yog kwv yees.
Kev ntsuas tam sim no yog nyob ntawm cov xwm txheej hauv qab no:
• Tus neeg xyuas pib kub nce siab tshaj ambient ntawm 40 ° C
• Ambient cua kub.ntawm 35 ° C rau lub caij ntuj sov tav su lossis 10 ° C rau lub caij ntuj no hmo ntuj
• Lub hnub ci hluav taws xob ncaj qha ntawm 1000 W / m2 rau lub caij ntuj sov tav su lossis xoom rau hmo ntuj caij ntuj no
• Diffuse solar radiation intensity of 100 W/m2 for summer tav su los zero for winter night • Av reflectance of 0.2
• Emissivity thiab solar absorption coefficient ntawm tus neeg xyuas pib nto, 0.5
