Kev thauj mus los hauv kev tsheb ciav hlau: Lub tshuab hluav taws xob traction rau siab - tsheb ciav hlau ceev- xws li siab - kev tsheb ciav hlau ceev thiab hluav taws xob ntau chav (EMUs)- xav tau ntau lub tshuab hluav taws xob los pab txhawb kev hloov hluav taws xob thiab xa hluav taws xob. Cov transformers no yuav tsum muaj peev xwm ua tau raws li qhov tshwj xeeb xav tau lub zog tshwj xeeb uas cuam tshuam nrog kev pib, nres, thiab siab -kev khiav ceev ntawm cov tsheb ciav hlau, yog li muab lawv lub zog ruaj khov thiab txhim khu kev qha.
Nroog Rail Transit: Cov kab ke xws li subways thiab cov kab tsheb ciav hlau tseem vam khom rau cov khoom siv hluav taws xob kom ntseeg tau tias kev ua haujlwm zoo ntawm lawv cov khoom siv hluav taws xob, ua kom tau raws li qhov xav tau hluav taws xob ntawm ob qho tib si tsheb ciav hlau thiab chaw nres tsheb.
Kev Lag Luam Kev Lag Luam: Kev hloov pauv kuj tseem siv rau hauv aviation domain -tshwj xeeb hauv tshav dav hlau hauv av hluav taws xob cov tshuab hluav taws xob thiab cov chaw ua haujlwm kho dav hlau- kom ua tau raws li ntau yam kev xav tau hluav taws xob.
