Umhlinzeki wephrofayela ye-Xingfa aluminium e-China uhlinzeka ngo-Line 18 nge-aluminium extrusion yangokwezifiso yemishini yokusekela imigqa yokwesekwa kwesistimu engaphezulu nezinye izisetshenziswa.
Ezinsukwini zakamuva, umugqa wokuqala we-Guangzhou Metro ulayini we-18 (Xiancun - Wanqingsha) uqalile ukusebenza, futhi isivinini sawo esikhulu sifinyelela ku-160 km/h, obizwa 'nge-metro esheshayo e-Guangdong-Hong Kong-Macao Greater Bay Area'. XINGFAi-aluminiumumphakeli wephrofayela e-China inikeza Line 18 ngengokwezifiso i-aluminium extrusion imigqa engaphezulu yesistimu yokusekela i-catenary nezinye izesekeli.
Ukwakhiwa kwenethiwekhi yezitimela kuyadingeka ekuthuthukisweni kwedolobha. Ngokuthuthuka kwedolobha, isidingo sezokuthutha zomphakathi sikhule ngokushesha. Izinto zokuhamba zikaloliwe zasedolobheni ziwumgogodla wezokuthutha, ngokuhambisana nemigomo yentuthuko eqhubekayo, ikakhulukazi yedolobha elikhulu. Eminyakeni yamuva nje, ukwakhiwa kwenethiwekhi yezitimela kwaqala ezweni lonke. Isitimela esinesivinini esiphezulu, ujantshi wesitimela kanye ne-metro kwase kunabele ezindaweni ezahlukene ngokujulile.
Ingxenye yokuqala ye-Guangzhou Metro Line 18 isiqalile ukusebenza, isivinini esikhulu sifinyelela ku-160km/h esibizwa nangokuthi ‘i-metro esheshayo e-Greater Bay. Imiklamo yobuciko esiteshini ibonise ngeso lengqondo amasevisi asempumalanga nabasebenzisi futhi yanikeza ukuzizwisa okunethezeka, okulula nokubanzi. Uma ukwakhiwa sekuqediwe, uLayini we-18 uzoba yisizinda esikhulu esixhuma inyakatho neningizimu ye-Guangzhou, ushintshe uhlaka lwenethiwekhi yezitimela zedolobha, kusheshiswe ukwakhiwa kwezokuthutha okudidiyelwe emazweni ngamazwe, kusheshiswe ukuthuthukiswa kweThe Greater Bay.
I-XINGFA, njengophawu lwamaphrofayili e-aluminium owaziwayo phakathi kwemboni yonke, iqhubeka nokucwaninga ngamaphrofayili e-aluminium eqhubayo kamasipala ngaso sonke isikhathi. Kube ngumphakeli omkhulu wamaphrofayili we-aluminium we-metro conductive kusukela ngo-1984.
Kulokhu, i-XINGFA inikeze amaphrofayili e-aluminium imikhiqizo engaphezulu kwemigqa nezinye izesekeli kanye nezinsiza zokuhlinzeka ngezinto ezibonakalayo zesistimu yokwesekwa kwe-Guangzhou Metro Line 18. Isizukulwane sesine semikhiqizo yebhasi ye-CR4 evela enkampanini eyaziwa umhlaba wonke i-Furrer+Frey AG e-Switzerland. . Ubuchwepheshe be-Furrer+Frey AG bebuyizinga elithuthukisiwe ngaphakathi naphesheya kwezilwandle. I-XINGFA isekela umugqa we-18 ongaguquki futhi usheshe ufakwe enkonzweni ngokusebenzisana nobuchwepheshe obusha obuthuthukisiwe obuhlukahlukene, indlela yokukhiqiza, ukulawula ikhwalithi ngenkonzo yobungcweti ephumelelayo.
Ibha yebhasi kaloliwe ezithuthukisiwe ye-XINGFA isetshenziswe kakhulu e-Guangzhou Metro, Nanjing Metro, Shanghai Metro, Lanwu Metro njengobuso bayo obuhambisayo, obukhudlwana bempambanomgwaqo, obufakwe kalula futhi obuzinzile. Ukuphathwa kwezinhlelo zokwesekwa kwesikhungo sikaloliwe kuphuliwe futhi kwavala igebe lokuhlinzekwa kwezidingo zasekhaya. Ithole umklomelo kazwelonke wesayensi nobuchwepheshe, osohlwini lwe-'China Torch Program'. Njengokwenza izinto ezintsha, imikhiqizo iyaqhubeka nokwethula isizukulwane sesithathu nesesine futhi ihola ukuthuthukiswa kwenethiwekhi yezitimela. Imikhiqizo ihlinzeka 'ngomhubhe omude kunawo wonke emhlabeni esifundeni sethafa-New Guanjiao Tunnel' kanye ne-South Xinjiang Uygur Autonomous Region-Zhongtianshan Tunnel' ukuze uthole imikhiqizo nezinsizakalo zebhasi yebhasi.
