(3) Malo oimika mafuta a m’tauni/malo oimikapo magalimoto otsegula: konzani macharidwe amphamvu kwambiri kuti muchepetse malire akuchapira.Pakalipano, PetroChina ikugwiritsa ntchito zipangizo zolipiritsa / zosinthana mofulumira m'munda watsopano wamagetsi, ndipo zikuyembekezeredwa kuti malo opangira mafuta ochulukirapo azikhala ndi milu yothamanga mofulumira m'tsogolomu.
Zindikirani: Malo a malo opangira gasi / malo otsegula otsegula okha ali pafupi ndi msewu ndipo mawonekedwe a nyumbayo ndi omveka bwino, omwe ndi abwino kwa ogula makasitomala kuti apeze muluwo mwamsanga ndikusiya malowa mwamsanga.

Pakalipano, dongosolo la 800V likukumanabe ndi zovuta zambiri pamtengo, zamakono ndi zomangamanga.Zovuta izi ndi njira yokhayo yopangira zatsopano komanso chitukuko chaukadaulo wamagalimoto amagetsi atsopano komanso kubwereza kwa mafakitale.siteji.
Makampani opanga magalimoto aku China, omwe ali ndi luso lachangu komanso logwira ntchito la uinjiniya, atha kuzindikira kuchuluka kwachangu kwa machitidwe a 800V, ndikutsogolera kutsogolera kwaukadaulo pantchito yamagalimoto amagetsi atsopano.
Ogula aku China adzakhalanso oyamba kusangalala ndi magalimoto apamwamba omwe amadza chifukwa cha kupita patsogolo kwaukadaulo.Sizilinso ngati nthawi ya magalimoto amafuta, pomwe ogula apanyumba amagula zitsanzo zakale kuchokera kumakampani amitundu yamitundu yamagalimoto, ukadaulo wakale kapena ukadaulo wothena.
