Railways yog ib feem tseem ceeb ntawm txoj kev thauj mus los thiab ib txoj haujlwm tseem ceeb ntawm kev ua neej nyob. Nyob rau hauv cov ntsiab lus ntawm lub teb chaws txoj kev loj hlob ntawm cov tshiab infrastructure, nws yog ib qhov zoo tshaj plaws los mus nce railway peev thiab kev tsim kho, uas yuav ua si lub luag hauj lwm zoo nyob rau hauv stimulating economic kev loj hlob thiab kev loj hlob ntawm muaj feem xyuam rau cov chains. Vim li no, lub xeev tau siv zog txhawb kev tsim kho kev tsheb ciav hlau, tshwj xeeb tshaj yog kev tsheb ciav hlau ceev, nyob rau xyoo tas los no, thiab cov kev lag luam sab saud thiab qis qis kuj tau txais txiaj ntsig.
Raws li ib tug cable rau muab lub zog thiab xa cov teeb liab nyob rau hauv locomotives, nws kuj tau nce nrog kev loj hlob ntawm Suav locomotives. Txawm li cas los xij, txawm hais tias kev lag luam hauv kev lag luam cable tau coj los ua lub sijhawm ua lag luam, tom qab lub sijhawm ua lag luam ntau, kev ua lag luam kuj tau muab cov kev cai nruj heev rau nws.
Raws li lub neej network ntawm lub locomotive, lub locomotive cable nqa cov kis ntawm cov ntaub ntawv sab hauv thiab sab nraud, tswj cov teeb liab thiab cov ntaub ntawv fais fab ntawm lub locomotive. Cov kab hluav taws xob feem ntau yog nyob ib puag ncig lossis hla ntawm cov hlau thav duab, thiab lawv qhov chaw hluav taws xob yog qhov nyuaj heev. Thaum lub locomotive khiav mus ntev, nws raug cuam tshuam los ntawm cov teeb meem tsis zoo xws li ablation, corrosion, av noo, siab thiab qis kub, thiab nws cov sheath sab nraud yog yooj yim heev. Yog tias muaj kev puas tsuaj, tej zaum yuav muaj ntau yam kev nyab xeeb.
Aipu Wharton tsom mus rau kev tshawb nrhiav txuas ntxiv ntawm daim ntawv thov teb ntawm hlau thiab cable. Qhov tshwj xeeb cov ntaub ntawv cable rau locomotive txais yuav ib tug tshiab-txheej txheej tiv thaiv qauv, oxygen-dawb tooj liab core, thiab saum npoo yog them nrog ib tug insulating txheej txheej. Cov txheej txheej yog roj-resistant, nplaim-retardant, thiab halogen-dawb (tsawg pa luam yeeb thiab halogen-dawb), yog li txo cov teeb meem tshuaj muaj nyob rau hauv cov pa luam yeeb tsim nyob rau hauv thaum muaj xwm ceev, coj mus rau hauv tus account tus yam ntxwv ntawm kev poob qis thiab ruaj khov-amplitude cables, thiab ua rau muaj kev tiv thaiv ib puag ncig ntawm locomotive cables, kom ntseeg tau tias kev ua haujlwm zoo ntawm locomotives, zam ntau yam kev pheej hmoo.
| Yam khoom | LSZH tiv thaiv cov ntaub ntawv cable | Cat.5e 4-pair UTP nrog LSZH sheath | Cat.6e 4-pair UTP nrog LSZH sheath |
| Khoom qauv | 2 x 24 AWG | 4 x 22 AWG | 4 P × 26 AWG |
| Txoj kab uas hla ntawm cov khoom tiav | 6.70 ± 0.3 hli | 6.60 ± 0.2 hli | 6.60 ± 0.3 hli |
Nrog nws cov yam ntxwv tshwj xeeb, cov ntaub ntawv tshwj xeeb cable rau locomotives yog tsim rau daim ntawv thov ntawm cables nyob rau hauv lub internal fais fab mov system, kev sib txuas lus thiab tswj system ntawm rail transit locomotives (subway, mos txwv tsheb ciav hlau, nroog teeb rail, thiab lwm yam).
R & D thiab zus tau tej cov cables kev, coj txoj kev loj hlob ntawm kev lag luam, nyob rau hauv txoj kev ntawm innovation, Aipu Waton, yog siv zog mus rau pem hauv ntej.
Cia li mus dhau!
