Xaiv cov khoom siv zoo rau cov kab hluav taws xob ruaj khov thiab ruaj khov
Thaum nws los txog rau cov ntawv thov kev lag luam uas yuav tsum tau siv cov cables, nws yog ib qho tseem ceeb uas yuav tsum xaiv cov khoom siv ruaj khov thiab ruaj khov. Cov ntaub ntawv no yuav tsum muaj peev xwm tiv taus qhov kub thiab txias, noo noo, siab, thiab lwm yam hnyav ib puag ncig uas cov cables raug rau txhua hnub. Cov ntaub ntawv tsim nyog tuaj yeem ua kom ntseeg tau tias cov cables tseem ua haujlwm, nyab xeeb, thiab ua haujlwm tau zoo thaum lub sijhawm lawv lub neej, ua rau lawv muaj peev xwm zoo rau kev lag luam.
Ntawm qhov tseem ceeb ntawm kev tsim kho cable yog cov khoom siv hluav taws xob, uas yog lub luag haujlwm rau nqa hluav taws xob tam sim no. Cov neeg siv khoom tuaj yeem ua los ntawm ntau yam ntaub ntawv xws li tooj liab, aluminium, thiab nyiaj-plated tooj liab. Tooj liab yog cov khoom siv feem ntau siv rau cov neeg siv hluav taws xob vim nws cov conductivity siab, tsis muaj zog, thiab kev ntseeg tag nrho.
Cov khoom siv rwb thaiv tsev kuj yog ib qho tseem ceeb hauv kev tsim kho cable. Cov ntaub ntawv rwb thaiv tsev tiv thaiv tus neeg xyuas pib ntawm corrosion, noo noo, thiab puas.
Cov ntaub ntawv rwb thaiv tsev muaj xws li PVC, XLPE, thiab Teflon. PVC, yog cov khoom siv uas tsis tshua muaj nqi thiab dav siv, feem ntau yog siv rau cov ntawv thov uas xav tau qhov ntsuas hluav taws xob tsawg thiab tam sim no. Txawm li cas los xij, rau kev thov ntau dua, XLPE yog cov khoom siv zoo dua vim nws cov thermal tsis kam thiab lub zog txhua yam. Teflon feem ntau yog siv rau kev siv kub-kub vim nws zoo heev thermal stability.
Cov khoom siv sheath yog lub luag haujlwm los tiv thaiv tus neeg xyuas pib thiab rwb thaiv tsev los ntawm kev puas tsuaj thiab ib puag ncig. Cov ntaub ntawv sheath muaj xws li PVC, Polyurethane, thiab Neoprene. PVC feem ntau xaiv vim nws tus nqi qis, yoog raws, thiab ua haujlwm zoo rau cov tshuaj.
Polyurethane feem ntau yog siv rau cov ntawv thov kev puas tsuaj thiab txiav tsis kam, xws li cov neeg hlau thiab cov tshuab automation. Neoprene yog qhov zoo tshaj plaws rau cov ntawv thov uas xav tau roj tsis kam thiab ua haujlwm hauv ntau qhov kub thiab txias.
Rau cov ntawv thov uas xav tau cov kab hluav taws xob ntau dua, cov khoom siv armor yog siv. Cov khoom siv armor tiv thaiv lub cable los ntawm kev cuam tshuam sab nraud, tsoo, thiab xuas nrig ntaus.
Cov khoom siv feem ntau muaj xws li steel, aluminium, thiab ntaub. Steel armor feem ntau yog siv rau hauv kev lag luam daim ntawv thov vim nws lub zog siab, thaum txhuas yog nyiam vim corrosion kuj thiab sib zog. Npuag, xws li Kevlar, yog siv rau daim ntaub ntawv uas yuav tsum tau zoo heev tiv thaiv puas thiab puncture.
Hauv kev xaiv cov khoom siv cable zoo, nws yog ib qho tseem ceeb uas yuav tsum xav txog cov kev cai tshwj xeeb ntawm daim ntawv thov. Cov yam tseem ceeb uas yuav tsum xav txog suav nrog kev ua haujlwm kub, qhov raug rau cov tshuaj lom neeg thiab cov khoom siv corrosive, qib ntawm cov neeg kho tshuab kev nyuaj siab, thiab qhov xav tau lifespan ntawm lub cable. Kev xaiv cov khoom tsim nyog tuaj yeem tiv thaiv kev tsis ua haujlwm ntawm cable, txhim kho kev ua tau zoo ntawm cable, thiab ua kom muaj peev xwm loj tshaj plaws hauv kev tsim kho cable.
