Amaxabiso eentambo zamandla ombane aphakathi nendawo aphezulu adlala indima ebalulekileyo-kumandla amakhulu, izinto eziluncedo, kunye neeprojekthi zemizi-mveliso. Ukuqonda indlela amaxabiso ababoneleli acwangciswa ngayo{2}}kunye nezinto eziphembelela iindleko, umgangatho, kunye nokuthotyelwa{3}}kunceda abathengi benze izigqibo zokuthenga benolwazi. Esi sikhokelo sibonelela ngeenkcukacha ezicacileyo, -eziqhutywayo eziqhutywa ngamaxabiso eentambo ze-MV kunye ne-HV, iikontraka ezivumelayo, iifemu ze-EPC, kunye nabasasazi ukuba bathelekise ababoneleli, uhlahlo lwabiwo-mali lolawulo, kunye nezisombululo ezithembekileyo zothumelo lwamandla.
Ziziphi iiCables eziPhakathi neziPhezulu zombane?
Iintambo zamandla ombane ophakathi (MV) zinikwa umlinganiselo ngokwesiqheloI-1 kV ukuya kuma-35 kVkwaye zisetyenziswa ngokubanzi kuthungelwano lokuhambisa amandla, izitishi, amaziko oshishino, kunye neeprojekthi zamandla ahlaziyekayo. Iintambo zombane ophezulu (HV) zisebenza ngasentla35 kV, exhasa-uthumelo lwamandla omgama kunye neenkqubo zegridi yesizwe.
Xa kuthelekiswa-neentambo zombane ezisezantsi, iintambo zeMV kunye neHV zifuna:
Iinkqubo zokugquma ezityebileyo
Ukhuseleko lombane olomeleziweyo
Uvavanyo olungqongqo kunye nesiqinisekiso
Ezi mfuno zobugcisa zinempembelelo kakhulu kwixabiso lentengiso kunye nokukhetha ababoneleli.
Asebenza Njani Amaxabiso Omthengisi?
IhoyilesiI-MV kunye ne-HV amaxabiso cable acatshulwe ngokubanzingemitha nganye okanye ngekhilomithakunye nokuncipha njengoko imiqulu yeodolo isanda. Ababoneleli badla ngokufaka amaxabiso anemigangatho esekwe koku:
Ubude bentambo bubonke obu-odolweyo
Izinto zeconductor (ubhedu okanye ialuminiyam)
Ukulinganiswa kwamandla ombane kunye nobunzima bokwakha
Kubathengi, amaxabiso ehoseyile enzelwe ukuvuza ukuthenga okuninzi,{0}}izivumelwano zexesha elide, kunye nemigaqo esemgangathweni.
Zeziphi Izinto Ezona Ziphembelela Amaxabiso eCable ePhakathi kunye naPhezulu?
Ziliqela izinto eziphambili ezimisela ixabiso lokugqibela lomthengisi:
Izinto zoMxolisi
Iintambo zobhedu zixabisa kakhulu ngenxa yexabiso eliphezulu lezinto ezisetyenziswayo, ngelixa ialuminiyam ibonelela ngeendleko eziphantsi-ezinye kwiiprojekthi ezinkulu.
Ixabiso lombane
Amazinga ombane aphezulu afuna ukugquma okungqindilili kunye nokhuselo oluphezulu, ukonyusa iindleko zokwenziwa nokuvavanya.
Uhlobo lwe-Insulation
I-XLPE (i-cross{0}}i-polyethylene edityanisiweyo) yeyona nto ixhaphakileyo yokugquma kwiintambo ze-MV kunye ne-HV ngenxa yokusebenza kwayo kwe-thermal kunye nombane, kodwa ixabisa ngaphezu kweenkqubo ezisisiseko zePVC.
Isikrweqe kunye noKhuselo
Isikrweqe socingo lwentsimbi (i-SWA) okanye isikrweqe seteyiphu siyalonyusa ixabiso kodwa siyimfuneko kufakelo oluphantsi komhlaba okanye olufunwa ngoomatshini.
Ngawaphi amaXabiso aQhelekileyo eWholeyile?
Ngelixa amaxabiso esahluka ngokwengingqi kunye nokucaciswa, iibenchmark zentengiso zibonelela ngesikhokelo esiluncedo:
IiCables Voltage eziPhakathi (6–33 kV):
Amaxabiso eWholesale ngokuqhelekileyo aqala ukusukangemitha nganye, kuxhomekeke kubungakanani bomqhubi, ukugquma, kunye nezixhobo.
Iintambo zombane oPhezulu (Ezinkulu kuno okanye zilingana ne-66 kV):
Iintambo zeHV eziphantsi komhlaba zinokusukelangekhilomitha nganye, ngakumbi kwigridi kunye neeprojekthi zothumelo.
Abathengi kufuneka bahlale bethelekisa amaxabiso asekelwe kwiinkcukacha ezifanayo zobugcisa kunokuba amanani entloko
Ingaba iziQinisekiso kunye neMigangatho zilichaphazela njani iXabiso?
Iintambo ezenziwe ngokwemigangatho yamazwe ngamazwe zihlala zibiza ngaphezulu kodwa zinciphisa kakhulu umngcipheko weprojekthi. Imigangatho eqhelekileyo iquka:
IEC 60502 / IEC 60840 / IEC 62067
IEEE kunye nemigangatho ye-ICEA
Iinkqubo zolawulo lomgangatho we-ISO 9001
Iintambo eziqinisekisiweyo ziqinisekisa ukhuseleko, ukungaguquguquki kokusebenza, kunye nothotyelo lolawulo{0}}lubalulekile kwizinto eziluncedo kunye{1}}neeprojekthi ezixhaswa ngurhulumente.
Kutheni le nto amaxabiso ezinto ezikrwada ebaluleke kangaka?
I-akhawunti ye-Copper kunye ne-aluminium yepesenti enkulu yeendleko zentambo ze-MV kunye ne-HV. Ukuguquguquka kwexabiso lentsimbi yehlabathi jikelele kunokubangela utshintsho olubonakalayo kwiingcaphuno zababoneleli, ngamanye amaxesha kwiiveki.
Kubathengi, oku kuthetha:
Ukuvala amaxabiso ngezivumelwano kunokunciphisa umngcipheko wohlahlo lwabiwo-mali
Ubudlelwane bexesha elide{0}}nokunikezela ngamaxabiso azinzileyo
Ukuthengwa kwexesha ngexesha leemeko ezifanelekileyo zemarike kunokuvelisa ugcino olubalulekileyo.
Abathengi banokuthelekisa njani ababoneleli ngeCable yeWholeliseli ngokufanelekileyo?
Ukwenza uthelekiso oluchanekileyo, abathengi kufuneka:
Tshatisa umlinganiselo wombane, ubungakanani be-conductor, ukugquma, kunye nokuxhobisa ngokuthe ngqo
Cela iingxelo zovavanyo kunye namaxwebhu okuthotyelwa
Thelekisa amaxesha okuhanjiswa kweenkonzo kunye neendleko zolungiselelo
Vavanya umthamo wemveliso yomthengisi kunye namava okuthumela ngaphandle
Zeziphi ezona ndlela zilungileyo zokuthenga iiCables zeMV kunye neHV kwiWholesale?
Ukufumana okuyimpumelelo kuxhomekeke kwindlela-yeendleko ezipheleleyo:
Ukuthenga okusekwe kukufaneleka kobugcisa, hayi ixabiso lodwa
Thetha ngezaphulelo zevolumu kunye{0}}nezivumelwano zobonelelo lwexesha elide
Qinisekisa iwaranti, uvavanyo, nasemva{0}}inkxaso yokuthengisa
Qwalasela iindleko zomjikelo wobomi, kubandakanywa ukufakela nokugcinwa
Indlela yokuchonga aIxabiso loMboneleli weeCables eziPhakathi kunye neziPhezulu zeVoltage?
