Railway locomotive cables muaj nyob rau hauv tshwj xeeb cables thiab ntsib ntau yam hnyav ntuj puag ncig thaum siv.
Cov no suav nrog qhov kub thiab txias sib txawv ntawm nruab hnub thiab hmo ntuj, tshav ntuj raug, huab cua, av noo, acid nag, khov, dej hiav txwv, thiab lwm yam. Tag nrho cov yam ntxwv no tuaj yeem cuam tshuam rau cable txoj sia thiab kev ua haujlwm, txawm tias txo nws txoj kev ntseeg siab thiab kev nyab xeeb, ua rau muaj kev puas tsuaj ntawm cov khoom. thiab tus kheej raug mob.
Yog li ntawd, cables rau tsheb thauj mus los yuav tsum muaj cov yam ntxwv hauv qab no:
1. Cov pa luam yeeb tsawg, tsis muaj halogen, nplaim taws-retardant zog
Tsim cov pa luam yeeb tsawg heev thaum lub sij hawm hluav taws xob hluav taws xob, lub teeb xa hluav taws xob ≥70%, tsis muaj cov khoom tsim kev puas tsuaj xws li halogens uas cuam tshuam rau tib neeg kev noj qab haus huv, thiab pH tus nqi ≥4.3 thaum combustion.
Cov khoom siv hluav taws xob hluav taws xob yuav tsum ua kom tau raws li cov kev xav tau ntawm ib leeg-cable burning tests, bundled-cable burning tests, thiab bundled-cable burning tests tom qab roj tsis kam.
2. Nyias-walled,high mechanical kev ua tau zoo
Cables rau qhov chaw tshwj xeeb xav tau nyias rwb thaiv tsev thickness, lub teeb yuag, siab yooj, khoov tsis kam, thiab hnav tsis kam, nrog siab tensile zog yuav tsum.
3. Waterproof, acid-alkali tsis kam, roj kuj, ozone kuj
Ntsuas cov kev hloov hauv tensile lub zog thiab elongation tus nqi ntawm cov cables tom qab roj kuj. Qee cov khoom raug kuaj rau lub zog dielectric tom qab roj tsis kam.
4. High-temperature resistance, low-temperature resistance
Cables tswj kev ua haujlwm zoo heev hauv qhov chaw siab lossis tsis tshua muaj qhov kub thiab txias yam tsis muaj qhov tawg tom qab raug rau qhov kub thiab txias.
