Ua tiav rwb thaiv tsev:Cov khoom ua kom tag nrho cov rwb thaiv tsev kev ntseeg tau.
Lub teeb thiab muaj zog:Qhov sib xyaw rail sib koom ua ke yog ob qho tib si hnav thiab ruaj khov.
Kev kub siab dav:Nws tuaj yeem siv dav hauv qhov kub thiab txias thiab muaj kev tiv thaiv zoo hauv qhov kub thiab txias (-55 degree ~ 85 degree ).
Kev Kho Tus Nqi Zoo:Tus nqi tu qis thiab kev daws teeb meem zoo ua rau nws ua tau zoo.
Qhov sib xyaw rail sib koom ua tiav kev rwb thaiv tsev zoo vim yog cov khoom siv zoo tshaj plaws. Nws sawv cev rau cov khoom lag luam tshiab tsim los ntawm cov khoom siv tshiab, muaj peev xwm hloov tau tag nrho cov khoom siv hluav taws xob insulated rail pob qij txha thiab glued rail pob qij txha tam sim no siv nyob rau hauv railway kab. Tsis tas li ntawd, nws hais txog qhov kev pheej hmoo ntawm kev puas tsuaj rau cov hlab ntsha thiab cov gaskets, txo qhov tshwm sim ntawm "liab band" nyob rau hauv kev sib tw khiav thiab txhim kho tag nrho kev nyab xeeb ntawm kev khiav tsheb ciav hlau.
