PTYA, PTYLA thiab PTVV yog cov kab hluav taws xob tseem ceeb hauv kev tsheb ciav hlau siv dav hauv kev tsheb ciav hlau thauj mus los, tsis siv neeg thaiv thiab kev cuam tshuam kev tswj hwm. Peb cov qauv sib txawv tshwj xeeb hauv cov qauv sheath, shielding kev ua tau zoo thiab qib kev tiv thaiv txhua yam. Kev xaiv tsim nyog yuav tsum yog nyob ntawm - qhov chaw electromagnetic cuam tshuam, nteg txoj kev thiab cov teeb liab xa mus.
PTYA railway signal cable txais 1.0mm² liab qab tooj liab conductor, insulated nrog siab - ntom polyethylene nrog ib tug tuab ntawm 0.5-0.7mm. Insulated cores yog cabled nyob rau hauv lub hnub qub -quad los yog paired twisting qauv. Nws yog longitudinally qhwv nrog aluminium-cov ntaub nplaum sib xyaw ua ke los ua ib qho kev sib xyaw ua ke, uas muab cov dej tsis haum, kev tiv thaiv hluav taws xob yooj yim thiab kev tiv thaiv me me. Derivative hom xws li PTYA22 thiab PTYA23 yog nruab nrog steel daim kab xev armor, nrog PVC los yog PE txheej sheath rau txhim kho compression thiab cuam tshuam. Qhov no cable yog tsim rau electrified railway seem thiab thaj chaw uas muaj zog hluav taws xob cuam tshuam. Nws yog feem ntau siv rau hauv faus nteg nyob rau hauv txoj kab tsheb ciav hlau rau zaus - hloov tsis siv neeg thaiv thiab lub teeb liab kis tau tus mob, zoo tagnrho rau lub sijhawm uas yuav tsum muaj cov dej noo yooj yim- pov thawj thiab tiv thaiv - cuam tshuam kev ua haujlwm.
PTYLA kuj tseem siv cov tooj liab liab liab thiab polyethylene rwb thaiv tsev. Nws lub ntsiab feature yog seamless aluminium sheath, nrog shielding coefficient tswj nyob rau hauv 0.3, xa ntau dua shielding efficiency tshaj lub composite sheath ntawm PTYA. Versions xws li PTYLA22 thiab PTYLA23 ntxiv steel daim kab xev armor thiab coj PVC los yog PE txheej sheath, kev txhim kho cov neeg kho tshuab kev tiv thaiv thiab corrosion kuj ho. Vim muaj kev tiv thaiv zoo tshaj - muaj peev xwm cuam tshuam, PTYLA muaj feem xyuam rau txoj kev tsheb ciav hlau loj nrog kev cuam tshuam hluav taws xob hnyav thiab cov teeb liab tseem ceeb nrog kev tiv thaiv siab. Nws yog dav siv nyob rau hauv siab - ceev railway traction fais fab kab thiab substations, zoo tiv thaiv teeb liab distortion los ntawm high- zaus hluav taws xob nrov.
PTVV yog cov yas yooj yim- sheathed railway teeb liab cable nrog cov qauv yooj yim. Nws muaj cov tooj liab liab tus neeg xyuas pib thiab polyethylene rwb thaiv tsev, them ncaj qha los ntawm PVC txheej sheath tsis muaj nplooj siab tiv thaiv los yog txheej armor. Cov tub ntxhais cable sib txawv ntawm 4 cores mus rau 61 cores. Insulated cores raug txheeb xyuas los ntawm cov xim xim, twisted rau hauv cable sib dhos thiab qhwv nrog polyester daim kab xev rau kev txhim kho cov qauv. Nrog tus nqi pheej yig thiab tsis muaj kev tiv thaiv tsim, PTVV yog siv rau hauv qhov chaw tsis muaj hluav taws xob tsis muaj hluav taws xob tsis muaj hluav taws xob cuam tshuam. Nws yog feem ntau nteg nyob rau hauv av, cable troughs los yog pipelines rau chaw nres tsheb nyob rau hauv lub teeb liab kev twb kev txuas thiab hluav taws kub tswb teeb liab kis tau tus mob, raws li zoo raws li cov neeg kho tshuab load tej yam kev mob.
Nyob rau hauv kev xaiv engineering, ib puag ncig kub thiab dabtsi yog khoov vojvoog yuav tsum tau coj mus rau hauv tus account. Qhov kub thiab txias ntawm PVC- sheathed cables yuav tsum tsis txhob qis dua 0℃. Rau armored cables, qhov tsawg kawg yog dabtsi yog khoov vojvoog yuav tsum tsis txhob tsawg tshaj li 15 npaug ntawm lub cable txheej kab.
Txoj kev xaiv dav dav ua raws li kev faib tawm kom meej: PTYLA rau kev cuam tshuam loj heev thiab cov teeb liab tseem ceeb ntawm cov kab siab -ceev rail traction kab; PTYA rau cov khoom siv hluav taws xob zoo ib yam xav tau kev sib npaug ntawm cov dej noo- pov thawj thiab kev tiv thaiv yooj yim; PTVV rau qhov zoo tib yam uas tsis yog- cuam tshuam chaw nres tsheb teeb liab xaim nrog tus nqi- xav tau zoo.
