Railway locomotive caboive cables rau cov cav tshwj xeeb thiab pom ntau qhov chaw hnyav hauv lub sijhawm siv.
Cov no suav nrog kev hloov kub loj ntawm nruab hnub thiab hmo ntuj raug, ua rau muaj kev ntseeg siab, ua rau muaj kev cia siab rau cov khoom siv thiab kev nyab xeeb, kev raug mob ntawm tus kheej.
Yog li ntawd, cables rau kev thauj tsheb thauj khoom yuav tsum muaj cov yam ntxwv hauv qab no:
1. Tsawg cov pa taws, halogen-free, nplaim taws-retardant thaj chaw
Tsim kom muaj cov pa luam yeeb tsawg tawg, lub teeb sib txuas los cuam tshuam ≥70%, tsis muaj kev ua phem rau tib neeg kev noj qab haus huv, thiab tus nqi sam ≥4.3 thaum sib txuas.
Cov nplaim taws-retardant thaj chaw yuav tsum ua kom tau raws li ib qho kev xav tau-cable hlawv cov kev ntsuam xyuas, thiab kev ntsuam xyuas-cable hlawv.
2.Qhov-phab ntsa,Kev Ua Haujlwm Zoo
Cables rau cov chaw tshwj xeeb xav kom muaj cov rwb thaiv tsev tuab, lub teeb kuj, thiab hnav tsis kam, nrog lub zog siab tensile yuav tsum tau ua.
3. Waterproof, Acid-Alkali Ua Luam, Roj Kuj, Ozone Kuj
Txheeb xyuas cov kev hloov hauv tensile muaj zog thiab muaj elongation tus nqi ntawm cov cable tom qab cov roj tsis kam. Qee cov khoom lag luam dhau los kuaj rau dielectric zog tom qab cov roj tsis kam.
4. Kev kub siab ua tsis kam, qis-kub tsis kam
Cables tswj kev ua tau zoo heev txhua yam kev ua haujlwm hauv qhov chaw siab lossis ib puag ncig qis heev uas tsis muaj kev tawg tom qab raug kev tawg rau tom qab muaj qhov siab lossis qis kub.
