Pofika mu 2024, pafupifupiAnthu 600 miliyoni ku sub Saharan Africa — 47% ya anthu onse — analibe magetsi, malinga ndiBungwe Lapadziko Lonse la Mphamvu. Ntchito 300Pulogalamu ya World Bank-African Development Bank, cholinga chake ndi kulumikiza anthu 300 miliyoni pofika chaka cha 2030. Mu ntchito yathu yotumiza kunja, kukwera kumeneku kukukhala funso limodzi lothandiza kwa magulu ogula zinthu: kodi mungapeze bwanji zinthu?zinthu zopangira nthaka ku AfricaMsika wa 's wokhudza mitengo womwe umapitilirabe zofunikira za IEC, chidebe pambuyo pa chidebe?
Ine ndine Jane Yang, manejala wogulitsa ku Xinchang Shibang New Material, komwe fakitale yathu yakhala ikupanga ndodo zoyambira pansi, ma conductor a nthaka ndi maenje owunikira kwa zaka zoposa 17. Mu bukhuli ndikufotokoza miyezo yomwe ma tender aku Africa amatchula, momwe timathandizira ogula kusankha pakati pa ndodo zoyambira zophimbidwa ndi galvanised ndi copper-clad potengera nthaka ndi bajeti, chifukwa chake kuba mkuwa kukukakamiza magetsi kuti apeze ma conductor achitsulo chophimbidwa ndi mkuwa (CCS), komanso momwe mungakonzekerere ma MOQ, nthawi yotsogolera ndi kukweza chidebe cha payipi ya projekiti m'malo mongoyitanitsa chinthu chimodzi.
- Anthu pafupifupi 600 miliyoni (47% ya anthu akumwera kwa Sahara ku Africa) analibe magetsi pofika chaka cha 2024, ndipo Mission 300 ikufuna kulumikiza magetsi atsopano 300 miliyoni pofika chaka cha 2030 — transformer iliyonse, pole top ndi mini-grid zomwe zamangidwazo ndi kugula kwa earthing.
- Ma tender a boma ku Africa akufotokoza miyezo ya dziko yochokera ku IEC — mwachitsanzo, tender ya boma la South Africa ya 2025, imafotokoza SANS 1063 ya ndodo za nthaka ndi SANS 10199 ya kapangidwe ka ma electrode a nthaka — kotero "kutsata malamulo apadera" ndi lamulo lolemba, osati mawu otsatsa.
- Tikukulangizani kugwiritsa ntchito ndodo zophwanyidwa ndi galvanised ground rods zomwe zimayikidwa m'madzi otentha kuti zisagwere pansi kwambiri komanso kuti zisagwere pansi kwambiri, komanso ndodo zophimbidwa ndi mkuwa (≥0.254 mm copper layer, ≥580 N/mm² tensile strength) komwe nthaka imawononga kapena ma electrode ayenera kuyendetsedwa mozama komanso molumikizana.
- Kuba mkuwa kumawonongera Eskom ku South Africa ndalama zokwana R5–7 biliyoni pachaka, kotero makina opangira zitsulo okhala ndi mkuwa — omwe ali ndi mtengo wochepa poyerekeza ndi zinyalala za mkuwa weniweni — amachotsa chilimbikitso cha kuba pamagetsi omwe amawonekera.
- Timauza ogula mapulogalamu kuti kusinthasintha kumaposa mtengo womwe ulipo: kuyenerera fakitale imodzi, kutseka zomwe zanenedweratu kwa miyezi 12, ndikutumiza makontena osakanikirana a SKU okhala ndi ndodo, ma conductor, ma clamp ndi maenje pamodzi.
Kukula kwa Kukwera kwa Magetsi ku Africa — ndi Kufunika kwa Zipangizo Zopangira Dothi
Tikuganiza kuti ziwerengero zazikuluzikulu ndizoyenera kuyimitsa, chifukwa zimafotokoza kukula kwa msika wa nthaka kwa zaka khumi zapitazi. Kutsatira koyamba kwa IEA pankhani ya ndalama zopezera magetsi kwapeza kutizosakwana USD 2.5 biliyoni pachakapakadali pano ikudzipereka kutseka kusiyana kwa mwayi wopeza zinthu ku sub Saharan Africa, ndi pafupifupi48% ya ndalamazo zimapita ku gridi yolumikizirana ndi anthuNdalama zothandizira njira zogawikana — ma grid ang'onoang'ono ndi machitidwe odziyimira pawokha — zidakula ndi 20% pakati pa 2019 ndi 2023, ndipo maboma aku Africa adapereka USD 1.9 biliyoni kuti agwiritse ntchito magetsi mu bajeti zawo za dziko la 2025, pafupifupi gawo limodzi mwa magawo atatu a bajeti yonse yamagetsi.
Kuchokera pamalingaliro athu, Mission 300 ndi pulogalamu yomwe imasintha nthawi. Banki Yapadziko Lonse yadzipereka kulumikiza anthu 250 miliyoni ndi African Development Bank ena 50 miliyoni, kuti pakhale kulumikizana kwatsopano kwa anthu 300 miliyoni pofika chaka cha 2030. Pulogalamuyi inanena za chochitika chake choyamba mu June 2026: anthu opitilira 50 miliyoni alumikizidwa m'maiko 40. Tikumva izi m'buku lathu la maoda - m'zaka ziwiri zapitazi maoda athu obwerezabwereza a makontena ochokera kwa ogulitsa omwe akutumikira makontrakitala amagetsi aku East ndi West Africa akukula pang'onopang'ono, ndipo mafunso omwe timalandira akutchula kwambiri mapulogalamu othandizidwa ndi magetsi omwe amatchulidwa mayina awo.
Tikuwona choyendetsa chachiwiri, chodekha. Mu zotumiza zathu, ma mini-grid ndi makina opangira magetsi a dzuwa akukulira limodzi ndi grid extension, ndipo okhazikitsa awo amafunikira zida zofanana zoyeretsera nthaka m'magulu ang'onoang'ono komanso ofala. Tsopano tikunyamula zidebe zosakanikirana za ogulitsa angapo aku Africa omwe amaphatikiza ndodo zazikulu zapansi za makontrakitala ogwira ntchito ndi ndodo zazifupi ndi zolumikizira zazing'ono za okhazikitsa magetsi a dzuwa omwe sagwira ntchito pa grid — fakitale imodzi, njira ziwiri zofunira, ndi imodzi yotumizira.
Kodi "Kutsatira Malamulo Okhazikika" Kumatanthauza Chiyani Mu Kugula Zinthu Zamagetsi ku Africa?
Malinga ndi zomwe takumana nazo, ogula omwe akufunafunazipangizo zamagetsi zopakira nthakaimakumana ndi vuto la mawu mwachangu. Miyezo yambiri ya Anglophone ku Africa imachokera ku IEC, monga momwe zikalata za ma tender zimanenerakukumba nthaka; kuyika pansindi mawu a ku America a NEC. Khodi ya waya ya ku South Africa ya SANS 10142-1 imachokera ku IEC 60364, Kenya imagwiritsa ntchito miyezo ya KS IEC, ndipo Nigeria imagwiritsa ntchito miyezo ya IEC kudzera mu SON. Nthawi zonse timalangiza ogula kuti afufuze mawu onse awiri, chifukwa kusaka komwe kumagwiritsa ntchito mawu aku America okha sikuthandiza kwenikweni - ndichifukwa chake timalemba "earthing" choyamba ndi "grounding" chachiwiri m'zolemba zathu.
Kodi mtengo weniweni wa tendero wa ku Africa umafuna chiyani?Mtengo wa 2025 wa boma kuchokera ku OR Tambo District Municipality ku South Africandi chitsanzo chabwino cha anthu onse: zimafuna kuti machitidwe odulira nthaka azitsatiraSANS 1063(ndodo za nthaka, zolumikizira ndi zolumikizira),SANS 10199(kapangidwe ndi kukhazikitsidwa kwa ma electrode a dziko lapansi),SANS 10292(kukonza makina ogawa magetsi otsika) ndiSANS 62305-3(chitetezo cha mphezi cha nyumba). Tikuwona maumboni ofanana ochokera ku SANS- ndi IEC muzofotokozera zautumiki ku kontinenti yonse.
Malangizo athu kwa omwe amabwera koyamba ndi lamulo la zikalata zitatu. Tikukulimbikitsani kufunsa satifiketi ya mphero pa chitsulo chapakati, lipoti la chophimba — makulidwe a zinc a ndodo zophimbidwa ndi galvanised, makulidwe a mkuwa a copper-clad — ndi mayeso a batch tensile. Ngati mtengo wa oda ukugwirizana ndi izi, timakonza zowunikira za SGS kapena Bureau Veritas tisanayike chidebe, ndipo taphunzira kuti oyang'anira magetsi amasamala kwambiri za mapepala awa kuposa kujambula zithunzi zama brosha.
Ndodo Zophikidwa ndi Galvanized vs Copper-Clad: Kusankha Potengera Dothi, Ndalama Zogulira ndi Moyo Wopangidwa
Mu fakitale yathu, iyi ndi chisankho chosankha chomwe chimalimbikitsa kwambiriKugula zinthu zothandizira ku Africazokambirana. Mitundu yonse iwiri ya ndodo ndi yachitsulo ndipo imatha kuyendetsedwa; imasiyana ndi utoto womwe umawateteza ku dothi. Timagwiritsa ntchito njira zotsatirazi pamene wogulitsa atitumizira lipoti la polojekiti:
| Muyeso | Ndodo Yotenthedwa ndi Galvanized | Ndodo Yokutidwa ndi Mkuwa |
|---|---|---|
| Chophimba choteteza | Zinc layer, hot-dip yogwiritsidwa ntchito | Mkuwa wa electrolytic, ≥0.254 mm pa mndandanda wathu wa AF-0232, chiyero ≥99.95% |

Mu ntchito yathu yolangiza, kukana kwa nthaka ndiye chinthu chomwe chimasankha tebulo ili. Mbali yaikulu ya lamba wa Sahelian ndi mkati mwa kum'mwera kwa Africa imakhala pa nthaka youma, yamchenga kapena ya lateritic komwe ndodo imodzi yayifupi siidzafika pamlingo wovomerezeka. Tikupangira ndodo zazitali zokhala ndi mkuwa zomwe zimayendetsedwa m'magawo ogwirizana m'mikhalidwe imeneyo, kapena ndodo zingapo zolumikizidwa m'malo osiyanasiyana - ndodoyo ndi yotsika mtengo poyerekeza ndi mayeso olephera kuvomereza. Mu zomwe takumana nazo popereka chinyezi komanso kukana kochepa m'mphepete mwa nyanja ku West Africa, ndodo yolumikizidwa ndi ma galvanised nthawi zambiri imadutsa bwino ndikusunga bajeti yeniyeni pamlingo wa mayunitsi 10,000.
Njira yathu yodziwika bwino, ngati wogula sakudziwa, ndikufunsa muyeso wotsimikizira kukana kwa nthaka kapena kufotokozera malo, kenako nkupereka dongosolo logawanitsa - ndodo zomatidwa ndi galvanised kuti zikhale zosavuta 70% ya malo, zophimbidwa ndi mkuwa kuti zikhale zovuta 30%. Mutha kuwona mitundu yonse iwiri pa tsamba lathu.ndodo yophwanyidwa ndi galvanisedndindodo yophwanyika yokhala ndi mkuwamasamba azinthu, ndi banja lonse la ndodo patsamba lathutsamba la gulu la ndodo ya pansi.
Kuba Mkuwa Kukusintha Kusankha Kondakitala — Nkhani ya Waya wa CCS Earthing
Tikukhulupirira kuti palibe chitsogozo choona cha zinthu zopangira dothi ku Africa chomwe chinganyalanyaze kuba. Bungwe la Global Initiative Against Transnational Organized Crime lalembedwa m'buku lakeLipoti la Disembala 2023 lokhudza chuma cha mkuwa chosaloledwa ku South Africaakuti kuba mkuwa kumawononga ndalama zambiri ku EskomR5–7 biliyoni pachaka, kuphatikiza pafupifupi R2 biliyoni yowonjezera kuti ibwezeretse zingwe zomwe zabedwa— ndi kutayika komwe kumabwera chifukwa cha chuma chonse kukuyerekeza kufika pa R187 biliyoni. Transnet inanena za zochitika zokhudzana ndi mawaya obedwa opitilira makilomita 1,500. Tikudziwa kuti ma kondakitala ogwetsa nthaka — nthawi zambiri amadutsa m'mitengo yotseguka kapena yokwiriridwa pansi pafupi nawo — ndi gawo la chuma cha umbanda ichi.
Mu ndemanga zathu, chitsulo chophimbidwa ndi mkuwa ndiye yankho la uinjiniya lomwe mabungwe ambiri amagwiritsa ntchito tsopano. Waya wathu wa AF-0525 CCS wokhazikika umagwiritsa ntchito chitsulo cholimba kwambiri —560–1,040 MPakutengera mtundu — ndi wosanjikiza wa mkuwa wa 0.25 mm womwe umanyamula mphamvu yamagetsi. Timapanga mitundu ya conductivity kuyambira 15%–40% IACS, yokhala ndi mainchesi a monofilament kuyambira 1.4 mm mpaka 3.2 mm kuphatikiza kukhala ma conductor a 7 mpaka 37 a mainchesi a 4.2–22.5 mm, ndipo nthawi yogwirira ntchito yopangidwayo imaposa zaka 50 pansi pa nthaka. Mphamvu yathu yopangira pa mzerewu ndi mamita 100,000 pamwezi.
Sitikukangana kuti CCS imalowa m'malo mwa mkuwa kulikonse — mphasa za substation zomwe zimakhala ndi mphamvu zambiri zimakhalabe za mkuwa kapena zigawo zolemera za CCS. Mu mawu athu kwa ogulitsa aku Africa, CCS yakhala malangizo okhazikika akuyika gridi ya kumidziMa run, pole down-leads ndi mpanda womangirira pa feeders zazitali zakumidzi. Timafalitsa zonse zomwe zili patsamba lathuTsamba la malonda a waya wa CCS.
