Cat. 5e yog ib qho kev qhia tshwj xeeb ntawm cable uas hais txog nws txoj kev ua raws li Cat. 5e tus qauv, siab kis tus nqi, thiab tus nqi qis me ntsis yuam kev. Nws tuaj yeem txhawb nqa cov ntaub ntawv ceev ceev thiab cov teeb liab xa tawm video.
Thaum xaiv qhov hloov tau yooj yim UTP Cat.5e elevator cables, cov ntsiab lus hauv qab no yuav tsum raug sau tseg:
Cov khoom siv tus neeg xyuas pib: Xaiv cov khoom siv hluav taws xob zoo tuaj yeem ua kom muaj kev sib kis thiab hluav taws xob ua haujlwm ntawm cable. Cov khoom siv hluav taws xob muaj xws li tooj liab ntshiab, tin plated tooj liab, txhuas, thiab lwm yam.
Cov ntaub ntawv rwb thaiv tsev: Qhov zoo thiab kev ua haujlwm ntawm cov ntaub ntawv rwb thaiv tsev muaj kev cuam tshuam loj rau kev ua haujlwm hluav taws xob thiab kev pabcuam lub neej ntawm cov cables. Cov ntaub ntawv rwb thaiv tsev muaj xws li PVC, XLPE, thiab lwm yam.
Sheath khoom: Lub luag haujlwm ntawm cov khoom siv sheath yog los tiv thaiv tus neeg xyuas pib thiab rwb thaiv tsev txheej ntawm cable los ntawm kev puas tsuaj thiab ib puag ncig. Cov ntaub ntawv uas muaj xws li PVC, PUR, thiab lwm yam.
Lub zog tensile: of the elevator cables yuav tsum tau tiv taus ntau zaus khoov thiab ncab thaum lub sijhawm ua haujlwm of the elevator, yog li lawv yuav tsum muaj lub zog tensile siab. Xaiv cov cables ua los ntawm cov ntaub ntawv muaj zog tuaj yeem ua tau zoo dua qhov kev thov no.
Khoov vojvoog: Lub vojvoog dabtsi yog khoov ntawm elevator cables muaj qhov cuam tshuam loj rau lawv lub neej kev pabcuam. Xaiv cov cables nrog me me bending radii tuaj yeem hloov kho kom zoo dua rau cov kev xav tau khoov thaum lub sijhawm ua haujlwm of the elevator thiab txhim kho lub neej kev pabcuam ntawm cov cables.
Cov kev qhia tshwj xeeb ntawm kev hloov pauv UTP Cat.5e of the elevator cables feem ntau yog nyob ntawm qhov kev qhia tshwj xeeb thiab cov cai ntawm lub elevator. Tus neeg xyuas pib qauv feem ntau ntsuas hauv square millimeters (mm ²) Los sawv cev, cov lus qhia tshwj xeeb suav nrog 0.5mm ², 0.75mm ², 1mm ², 1.5mm ² Thiab 2.5mm ² Tos. Qhov chaw hla ntu yog hais txog thaj tsam ntawm qhov chaw hla ntawm tus neeg xyuas pib ntawm ib qho cable, feem ntau ntsuas hauv square millimeters (mm ²) Los sawv cev, cov lus qhia tshwj xeeb suav nrog 4mm ², 6mm ² Tos.
Tsis tas li ntawd, raws li qhov sib txawv ntawm kev siv ib puag ncig thiab kev xav tau, hloov tau yooj yim UTP Cat.5e of elevator cables kuj muaj cov kev qhia tshwj xeeb thiab cov kev txwv hauv qab no:
Cov khoom siv hluav taws xob: Ua los ntawm ntau txoj hlua khi ultra-fine twisted oxygen dawb tooj liab hlau, raws li VDE0295 Class 5 tus qauv.
Cov khoom siv rwb thaiv tsev: tshwj xeeb sib xyaw PVC rwb thaiv tsev yog siv.
Kev txheeb xyuas xim: Raws li GB5023.6 tus qauv, daj, dawb, txiv kab ntxwv, lub teeb ntsuab, liab dawb thiab lwm yam xim yog siv los txheeb xyuas.
Reinforcement: Lub zog siab galvanized aviation steel hlau tuaj yeem xaiv los ua qhov kev txhawb nqa.
Sheath khoom: Txias resistant PVC tshwj xeeb sheath, grey los yog dub.
Rated voltage: 300/500V.
Kev ntsuas hluav taws xob: 2500V.
Static dabtsi yog khoov vojvoog: Thaum lub sij hawm ib txwm siv, qhov siab tshaj plaws kub ntawm tus neeg xyuas pib yog 70 degree, thiab lub cable yog haum rau siv nyob rau hauv ib puag ncig ntawm -15 degree thiab +40 degree .
Kev ncua ntev: Nyob rau hauv ib lub paj paj twisted, qhov ncua kev kawm pub dawb yog ntau dua 80m thiab kev khiav hauj lwm ceev yog nyob nruab nrab ntawm 4.0m / s thiab 10.0m / s.
Load bearing Cheebtsam: Ntxiv galvanized soft steel hlau hlua los yog fiber ntau hlua xws li aramid yarn rau cable raws li load-bearing Cheebtsam.
