I-Shanghai Qinkai Industrial Co., Ltd., umenzi kunye nomthengisi weenkonzo zekhebula, isakhiwo sentsimbi kunye nezixhobo zokufakelwa kwelanga kwiiprojekthi zamandla kunye neziseko zophuhliso, ithe inikwe umsebenzi wokubonelela ngeprojekthi ye-photovoltaic kaRhulumente waseBangladesh, egubungela ii-conduits, amacandelo esinyithi, iipleyiti zegridi, ukwenziwa ngokwezifiso kunye nezixhobo.

Le scope ibeka iQinkai kwinto iqela layo lobunjineli eliyibiza ngokuba yi-structural and cable-routing layer yesityalo: amalungu athwala umthwalo phantsi kweemodyuli, iindlela ezithwala kwaye zikhusela iintambo zeDC kunye ne-AC, iindawo zentsimbi ezithwala umthwalo kunye nezihambayo, kunye nezixhobo zokudibanisa ezi zine.

“Asiziboneleli ngeemodyuli, kwaye yiloo nto kanye efunekayo,” utshilo inkampani kwingxelo. “Kwindawo yelanga esetyenziswa kakhulu, izinto ezigqiba ekubeni isityalo sifikelele kumhla woqhagamshelo lwegridi zingaphantsi kweemodyuli. Intsimbi efika ineendawo ezichanekileyo zemingxuma, umjelo ogcina amanzi aphuma kwimvula kude neengcingo zekhebula, kunye negrating ehlala ikhuselekile ukuhamba kuyo ubomi bonke besityalo zibalulekile kakhulu, azisetyenziswa. Inkqubo karhulumente izithenga ngesizathu esifanayo neso ithenga iimodyuli: isityalo asinakusebenza ngaphandle kwazo.”

Ishedyuli kwindawo yelanga igqitywa ngezantsi kweemodyuli

Iithenda kunye namaxwebhu emali axoxa nge-wattage yemodyuli kunye nomthamo ofakiweyo. Iishedyuli zesiza zicwangciswa ngeminye imibuzo emibini: ingaba iimodyuli zinokulungiswa ngokuthembekileyo na, kunye nokuba iintambo zinokuhanjiswa kwaye zikhuselwe ngokukhuselekileyo na. Zombini zixhomekeke kwintsimbi kunye nombhobho ofikayo kwimeko efanelekileyo, kulandelelwano olufanelekileyo lokufakelwa, kunye namaxwebhu afanelekileyo.

Yiloo nto kanye uQinkai athe ummandla wayo kwiprojekthi yaseBangladesh wakhiwe ngayo. Ezi ndidi zintlanu zibonelelweyo azikho zintlobo ngeentlobo zentsimbi kunye nezixhobo; nganye igubungela icandelo elithile lendlela yomthwalo kunye nendlela yentambo, kwaye nganye inendlela yokusilela ebonakala kwindawo kunokuba ibonakale kumzobo.

Oko kwenziwa ziindidi ezintlanu ezibonelelweyo kwindawo yelanga

• •IiConduit — ukhuseleko lweentambo kunye nolawulo lomzila.Iintambo zombane zithwala kwaye zikhusela iintambo ze-DC ngaphakathi kwi-array kunye neentambo ze-AC phakathi kwee-inverters, ii-transformers kunye nendawo yokudibanisa, zilawula i-bend radius ukuze kungabikho ntambo ixineneyo xa ijika. Umsebenzi wazo wesibini kukusingqongileyo: indlela yokuvala, ukuthintela amanzi kunye ne-conduit slope zichonga ukuba ukugeleza kwe-monsoon kufikelela na kwi-cable sheath kwaphela.
• •Iinxalenye zentsimbi — indlela yomthwalo.Iikholamu, imiqadi kunye ne-bracing ziqokelela uxinzelelo lomoya kunye nobunzima bomzimba ukusuka kumphezulu wemodyuli kwaye ziyidlulisele kwisigaba sesiseko ngesigaba. Izalathisi ezimbini zigqiba indlela esebenza ngayo le nto: ukuchaneka kwendawo yomngxuma, okumisela isantya sokuhlanganiswa kwindawo, kunye nomgangatho wokugquma, okumisela ubomi benkonzo. Isityalo se-photovoltaic sidla ngokuba senzelwe ubomi beminyaka engama-25, kwaye ugquma oluchasene nokugqwala kwintsimbi yesakhiwo yindlela loo mfanekiso ohlonitshwa ngayo.
• •Iipleyiti zegridi — iindawo abantu nezixhobo abanokuma kuzo.Iindlela zokuhamba ngononophelo, amaqonga ezixhobo kunye neendawo zonxibelelwano apho umthwalo oxineneyo kufuneka usasazwe kwindawo ebanzi yokuthwala. Umlinganiselo womthwalo kufuneka uhambelane nomthwalo wenkonzo, kwaye ukulungiswa kokugqwala kwimiphetho esikiweyo nakwiindawo ezisandula ukuwelda kufuneka kufikelele kukhuseleko olufanayo nolwezinto eziphambili - kwiindawo zokwenyani, imiphetho esikiweyo kunye nee-welds zezona zinto ziqala ngokugqwala.
• •Ukwenziwa ngokwezifiso — iindawo ezingezizo ezisemgangathweni ezikhokelwa kukuzoba.Izixhasi ezimile okwemilo, izihlanganisi zotshintsho, izinto ezibhoboziweyo nezigobileyo ezisombulula umahluko womgangatho womhlaba, ukuphambuka kwiziseko ezikhoyo kunye notshintsho phakathi kweenkqubo ezikwifektri, endaweni yokuzishiya zitshixiwe, zinqunyulwe kwaye zinyanzeliswe kwindawo. Umgangatho apha uxhomekeke kwinkqubo kunokuba ube nezixhobo: ukuvunywa komzobo ovaliweyo, ukuhlolwa kwento yokuqala kunye nokuhambelana kwebhetshi.
• •Izixhobo — ujongano lokuvala.Izinto zokubopha, izihlanganisi, ii-clamps, izinto zokuvala kunye nezokukhusela zithwala ixabiso eliphantsi leyunithi kunye nethuba eliphezulu lokubangela ingxaki. Zigqiba ekubeni zifaniswe izinto apho iintsimbi ezahlukeneyo zidibana khona kwimozulu eshushu nefumileyo yaselunxwemeni, ukuhambelana kwemingxunya neenxalenye zentsimbi kunye neepleyiti zegridi, kunye nokumelana nokukhuluphala phantsi kokungcangcazela komoya okuphindaphindiweyo.

Ilungiselelwe ubushushu, imvula enkulu kunye nokuchatshazelwa sisivunguvungu

IBangladesh idibanisa ubushushu obuphezulu kunye nokufuma, iinyanga zemvula yemvula kunye nokuvezwa yinkanyamba, indibaniselwano efuna ukhuseleko olungaphezulu kwintsimbi kunye nokumelana nomoya wesakhiwo kunezinye iimarike ezinobushushu obuphantsi.

UQinkai uthe inamandla okusebenzisa i-hot-dip galvanizing (HDG) kwiindawo zesakhiwo sentsimbi kwaye inokubonelela ngeerekhodi zovavanyo lobukhulu be-coating xa iceliwe, kwaye iindawo zentsimbi ezinde ziphathwa ngokwamacandelo aneepakethe eziqinisiweyo ukuze kuthintelwe ukugoba nokujika ngokuhamba kolwandle okude. Kwindlela yekhebula, iinkcukacha zeprojekthi zijongana neendawo ezivalekileyo ze-conduit kunye necala le-slope ukuze amanzi ageleza kumphezulu angangeni kwiindawo ezibalekayo.

“Izigqibo zokugqwala zenziwa kube kanye kwaye zihlawulwe kangangeminyaka engaphezu kwamashumi amabini,” utshilo inkampani. “Umthengi onciphisa uhlahlo-lwabiwo mali lokugquma kwiprojekthi yaselunxwemeni akongi imali, uhambisa iindleko kuphela kwixesha lokusebenza apho kubiza kakhulu ukulungisa.”

Ixabiso lale mpahla intlanu xa ithengwa ngokwahlukeneyo

Ityala lokuthatha intsimbi, i-conduit kunye nenkxaso yekhebula ukusuka kwenye indawo lidla ngokuxoxwa ngexabiso leyunithi. Ingxoxo kaQinkai iqala kwelinye icala endaweni yoko - kwinto ekufuneka yenziwe yindawo yelanga xa izinto ziphuma ngokunganyamezelani, zingalandeli ulandelelwano okanye zingalandeli miyalelo. Le nkampani ithe ihlola olu luhlu nabathengi ngaphambi kokuba icaphule:

•Imingxunya engami ndawonye iba yinto yomgca wabasebenzi.Xa izinto zentsimbi kunye nenkxaso yentambo zenziwe ngokubhekiselele kwiidatum ezimbini ezahlukeneyo zemingxuma, ukungalingani kuyavalwa kwindawo ngee-reamers, ii-shims kunye neeyure ezongezelelweyo zabasebenzi - kwaye i-node egqityiweyo ayisafani nendlela yomthwalo eyayicingelwa ngumyili.
•Ukwahluka kwemiphezulu yokugquma njengento ebangela ukugqwala, kungekhona isiphene sokuhanjiswa.Intsimbi evela kubathengisi abahlukeneyo ithetha ubukhulu obahlukeneyo bokugquma kunye nokunamathela. Kwindawo eshushu, efumileyo okanye eselunxwemeni, umahluko ubonakala njengoko umhlwa uphuma kwintsimbi yesakhiwo kunye neendlela zokuhamba, ezifunyenwe ngexesha lokuhlolwa komsebenzi emva kokuba uvavanyo lwangaphambi kokuthunyelwa lusayiniwe.
•Amanzi afikelela kwi-cable sheath ngokusebenzisa amalungu, kungekhona ngodonga.Umjelo womoya ochanekileyo ngokwemilinganiselo kodwa ongavalwanga kakuhle kwiindawo zokudibana kunye neziphelo ezivulekileyo ubeka ukhuselo lwentambo kwindawo yokudibana kwamanzi okusisigxina - imeko ebonakala kuphela xa uvavanyo lokhuselo luphindaphindwa kamva kwiprojekthi.
•Imiphetho esikiweyo kunye nee-welds ziindawo apho imiphezulu yendlela yokuhamba ingasebenzi khona kuqala.Ipleyiti kunye negrating ezi-odolwe ngaphandle kwemfuneko yokulungiswa kwemiphetho esikiweyo kunye neendawo ezisandula ukuwelda zicwangcisa umsebenzi wolondolozo kwiindawo apho uphahla lubhityile khona.
•Isikhongozeli esipakishwe ngabantu abangengabo abasapho siyalibazisa lonke icebo.Ukupakisha okubonakala kusebenza kakuhle kumzi-mveliso — ikreyithi enye yeebhrakhethi, enye yeepleyiti, enye yeconduit — kunyanzela indawo ukuba ivuleke kwaye ihlele yonke into ngaphambi kokuba kudityaniswe ibheyi enye. Iikreyithi ezipakishwe ngokulandelelana ziyasusa elo nyathelo.
•Abathengisi abaninzi bathetha ukuba akukho mntu unelungelo lokusebenzisa i-interface.Ukunyamezelana phakathi kwebracket ye-conduit, icandelo lentsimbi kunye nepleyiti akukho mntu unokukunika xa ezi zintathu zifika zivela kubathengisi abathathu abahlukeneyo.

“Zonke ezo zinto zintandathu zixabiso leshedyuli okanye iindleko zokulungisa, kwaye akukho nanye kuzo ebonakala xa kuthelekiswa ixabiso leyunithi,” utshilo inkampani. “Yiyo loo nto le nkqubo icatshulwe njengenkqubo endaweni yokuba ibe luluhlu lwezinto ezintlanu zokuthenga.”

Inani leminyaka engamashumi amabini lichithwa kwizinto ezingabonakaliyo kumgca

Isityalo se-photovoltaic sidla ngokuba senzelwe ubomi beminyaka engama-25. Iimodyuli ziyinxalenye yesityalo esitshintshwayo okanye esiphuculwayo; isakhiwo sentsimbi, uphahla olukuso kunye nendlela yentambo azinjalo. Izigqibo zeenkcukacha ezinemiphumo emide ke ngoko zezona zinzima ukuzibona kwinqanaba lokuthamba: inkqubo yophahla kunye nobukhulu obuncinci kwintsimbi yesakhiwo, indlela yokuvala kwiindawo zokuxhuma, ukulungiswa kokonakala kwimiphetho esikiweyo, kunye nokudibanisa izinto kwiindawo zokudibanisa ukuze iintsimbi ezahlukeneyo zingakhawulezisi ukubola emoyeni ofumileyo.

“Ezona zinto zibiza kancinci kwibhili yezinto zidla ngokubangela uninzi lwezinto ezifunekayo,” utshilo inkampani. “Isixhobo sokuncamathelisa, i-clamp, i-connector. Zikwazo izinto abathengi abanqwenela ukuzithenga ngokwahlukeneyo ukuze bonge ipesenti ezimbalwa. Leyo yindlela esingathanda ukuxoxa ngayo ngaphambi kokuba si-odole kunokuba siqale emva kokuyivula.”

Kukho iindlela ezimbini ezifunekayo eBangladesh — kwaye abazithengi intsimbi efanayo

Umbhobho waseBangladesh awulorhwebo olunye. Wahlulwe waba ziindlela ezimbini ezifunekayo ezineeseti zezinto ezahlukeneyo, imijikelo eyahlukeneyo yoku-odola kunye nemikhwa eyahlukeneyo yokubhala amaxwebhu. Iiprojekthi zenkqubo yobungakanani bezinto ezisetyenziswayo - izityalo ezifakwe emhlabeni ezineentambo ezinde zokuhamba, iindlela zokuhamba, amaqonga ezixhobo kunye neemfuno ezisesikweni zokunikezelwa - zithenga iindawo ezinzima zesakhiwo, iigridi kunye neendlela ezinde zokuhamba, ngokuchasene nemizobo eqandisiweyo kwiinyanga ngaphambi kokwenziwa. Umsebenzi osasazekileyo wophahla kunye nowezorhwebo kunye nowemizi-mveliso usebenza kumjikelo omfutshane, ngenkxaso elula nesemgangathweni ngakumbi, iindawo ezincinci zokuhamba, kunye nokunyamezela okuncinci kakhulu kokufakwa kwendawo.

Zombini iindlela zitsalwa ziinjongo ezifanayo zomgaqo-nkqubo. Umgaqo-nkqubo wamandla avuselelekayo waseBangladesh ka-2025 umisela isabelo esivuselelekayo se-20 ekhulwini kumxube wamandla kazwelonke ngo-2030 kunye ne-30 ekhulwini ngo-2040, ngokutsho kwengxelo-nkqubo kaJulayi 2026 evela kwiZiko loPhuhliso loShishino kwiYunivesithi yaseBRAC, echaza imfuno yemizi-mveliso yamandla acocekileyo njengenye yezinto ezibangela oku kujoliswe kuko. I-arhente yeendaba yesizwe i-BSS ibike ngoMeyi 7, 2026 ukuba urhulumente ulindele ukuba i-809.5 MW yokuveliswa kwamandla elanga ifike kwi-intanethi ekupheleni kuka-2028. I-Invest Bangladesh, i-arhente yokukhuthaza utyalo-mali yesizwe, iqikelela ukuba imakethi yelanga yelizwe iya kufikelela kwi-3.9 GW ngo-2030, ikhula ngesantya sonyaka esidibeneyo se-38.6 ekhulwini phakathi ko-2025 no-2030, ngokuchasene nomndilili wokukhanya kwelanga omalunga ne-5 kWh ngemitha yesikwere ngosuku.

Isiqingatha sophahla lombhobho sinomkhondo waso wemigaqo-nkqubo: iphephandaba lezoshishino laseBangladesh labika ngoMeyi 2026 ukuba urhulumente ucwangcise isakhelo esitsha semigaqo-nkqubo yokukhawulezisa ukusasazwa kwamandla elanga eluphahleni kunye nokutsala imali yabucala, isikhundla esadluliselwa liSebe lezoRhwebo lePhondo laseShandong laseTshayina ngoJuni 10, 2026. Abakhi baseTshayina sele beyinxalenye ebonakalayo yecala lokuhambisa, okwangoku. Iphephandaba iPeople's Daily labika ngoJuni 25, 2026 ukuba isityalo selanga sasePabna esingu-64 MW, esakhiwe ngumkhi waseTshayina, sifikelele kuqhagamshelo lwegridi olupheleleyo ngoJulayi 2025 kwaye sivelisa malunga ne-110 yezigidi ze-kWh zombane oluhlaza minyaka le.

Ezi ndlela zimbini ziyadibana kumbuzo omnye ocacileyo. Kwilizwe elineenyanga zemvula yemvula kunye nokuvezwa sisivuthuvuthu, ukhuseleko lokugqwala kunye nokhuseleko lweentambo ziphezulu kwiibhili zombini zezinto zokwakha, kwaye zombini ngoku zilindele iirekhodi endaweni yeziqinisekiso.

“Sicaphula ii-scopes zophahla kunye nezikali zezixhobo ezivela kwireferensi efanayo yobunjineli,” utshilo inkampani. “Intsimbi iba lula xa kusetyenzwa eluphahleni kwaye ibe nzima xa kusetyenzwa phantsi, kodwa imfuneko yokugquma, imfuneko yokutywina kunye nemfuneko yoxwebhu ayitshintshi. Leyo yinxalenye yomyalelo ohamba kuzo zombini iimarike.”

Apho i-odolo ilawulwa khona ngokwenene

Ukuthenga inkqubo ebhaliweyo kuthetha ukuba iindawo zolawulo ziyabonakala kunokuba zingachazwanga. UQinkai uthe iodolo yaseBangladesh idlula ezintandathu kuzo, kwaye umthengi okanye umhloli wesithathu unokubakho nangaliphi na ixesha:

•Ukuvalwa komzobo.Yonke into eyenziwe ngokwezifiso ikhutshwa ngokuhambelana nomzobo ovunyiweyo, kunye nohlaziyo olurekhodwe, ngaphambi kokuba kunqunyulwe nayiphi na into.
•Imvume yenqaku lokuqala.Inxalenye yokuqala yento nganye engaqhelekanga ijongwa ngokuthelekisa umzobo — iindawo zemingxuma, ubude bokusika, ii-engile zokugoba — ngaphambi kokuba ibhetshi iqale. Inqaku lokuqala elihambelanayo lolona qinisekiso lomgangatho olungabizi kakhulu olufumanekayo kwi-odolo yonke.
•Ukuhlolwa kwenkqubo.Iindawo zemingxuma kunye nomgangatho we-weld zijongwa ngexesha lokwenziwa endaweni yokuzifaka emva kwayo, ngoko ke ukuphambuka okucwangcisiweyo kubanjwa kwibhetshi yokuqala endaweni yekreyithi yokugqibela.
•Ukuqinisekiswa kokugquma.Ubukhulu kunye nokunamathela kwengubo kulinganiswa kwaye kurekhodwa ngebhetshi nganye, kwiirekhodi ezifanayo ezifunyanwa ngumthengi.
•Isicwangciso sokupakisha nokulayisha.Kwakhiwa iikreyithi kwaye izikhongozeli zilayishwa ngokulandelelana kokufakwa, kunye nesicwangciso sokulayisha esikhutshwe ngaphambi kokuba kuhanjwe ukuze indawo ikwazi ukucwangcisa ukwamkelwa ngokulandelelana ngokuchanekileyo.
•Uphononongo lwamaxwebhu ngaphambi kokuthunyelwa.Izatifikethi zezinto eziphathekayo, iingxelo zokuhlolwa kunye noluhlu lokupakisha ziyalinganiswa ngobungakanani obuhanjisiweyo ngaphambi kokuba isikhongozeli sihambe, singahlanganiswa emva koko.

“Zonke ezi ndawo zokulawula zibiza kancinci kunendlela ezithintela ngayo ukulungiswa kwendawo,” utshilo inkampani. “Ukulungiswa kwakhona ngaphakathi kwivenkile yokuvelisa izinto kulinganiswa ngeeyure. Ukulungiswa kwakhona kwindawo yelanga kulinganiswa ngeeveki, kwaye kuwela kwindawo apho kungekho manzi aseleyo.”
