Dab tsi yogtxias dov steel striprau armor?
Txias-rolled steel sawb rau armoring yog cov khoom tseem ceeb rau kev tiv thaiv sab nraud ntawm lub hwj chim cables, kev sib txuas lus cables, thiab lwm yam. Nws yog tsuas yog siv los txhim kho lub zog txhua yam, compression kuj thiab corrosion kuj ntawm cables.
Khoom siv
Lub zog siab: Lub zog tensile feem ntau yog 300 ~ 600MPa, kom ntseeg tau tias muaj zog sab nraud (xws li extrusion, nas gnawing).
Flexibility: Elongation Ntau dua lossis sib npaug li 20%, yooj yim rau kev khoov thiab tso.
Corrosion kuj: galvanized (zinc txheej 40 ~ 275g / m²) los yog pleev xim rau, haum rau av noo, acidic thiab alkaline ib puag ncig.
Dimensional raug: thickness 0.2 ~ 0.8mm (feem ntau 0.5mm), dav 20 ~ 100mm, kam rau ua ± 0.02mm.
Dab tsi yog Steel Tapes rau Armouring?
Lub zog cable
Nruab nrab thiab qis voltage cables (xws li YJV22, VV22)
Muab ob npaug rau- txheej galvanized steel siv qhov sib txawv wrapping, compressive zog Ntau dua los yog sib npaug rau 4000N / cm, haum rau hauv av ncaj qha faus thiab qhov tso.
High voltage cable (xws li YJLW03)
Interlocking armor (S-zoo li tus steel siv interlocking), zoo saj zawg zog thiab anti-torsion, haum rau complex struts.
Kev sib txuas lus cable
Optical cable (xws li GYTA53)
Longitudinal chrome-plated steel siv (thickness 0.15mm), tiv thaiv- nas tom, tiv thaiv electromagnetic cuam tshuam.
Mining kev sib txuas lus cable (MHYBV)
Nplaim retardant txheej + steel siv armor, ua tau raws li qhov tawg -cov ntaub ntawv pov thawj ntawm cov mines.
Tshwj xeeb cable
Submarine cable
Galvanized steel siv + PE txheej txheej, tiv taus seawater corrosion, tensile zog Ntau dua los yog sib npaug rau 10kN.
Roj platform cable
316L stainless hlau armor, resistant rau Cl⁻ corrosion (ntsev tshuaj tsuag > 2000 teev).
Lwm yam teb
Aerospace cables: Ultra- nyias stainless hlau daim kab xev (0.1mm) armor, txo qhov hnyav thiab kub tsis kam.
Nuclear fais fab nroj tsuag cables: Boron- muaj steel daim kab xev armor, ob qho tib si hluav taws xob tiv thaiv thiab kev tiv thaiv txhua yam.
