1. Yintoni intambo yamandla e-High Voltage?
Intambo yamandla yeVoliti ePhakamileyo yimveliso ebalulekileyo esetyenziswa kwiinkqubo zokudlulisa nokusasaza amandla ombane aphakathi naphezulu ukuze kuhanjiswe kwaye kusasazwe amandla ombane. Uvavanyo oluqhelekileyo lwevolthi luquka i-6kV, i-10kV, i-35kV, i-110kV nangaphezulu. Isetyenziswa kakhulu kwiigridi zamandla zasezidolophini, uthutho lwesitimela, ukuveliswa kwamandla ahlaziyekayo kunye neeprojekthi ezinkulu zeziseko zophuhliso.
Xa kuthelekiswa neentambo zemveli eziphezulu, iintambo zamandla ezinombane ophezulu zibonelela ngeenzuzo ezifana nokungahlali kakuhle emhlabeni, ukhuseleko oluphezulu kunye nokuziqhelanisa nokusingqongileyo okuqinileyo, okwenza ukuba zifaneleke ngakumbi kwiimeko zokufakelwa komhlaba ezidolophini. Ngokuphuculwa kwegridi kunye nophuhliso lwamandla ahlaziyekayo, iimfuno eziphezulu zibekwe ekuthembekeni kwexesha elide kunye nokusebenza kwezinto zeentambo.
2. Ulwakhiwo kunye nezixhobo ezibalulekileyo zekhebula lamandla e-High Voltage
Iintambo zamandla ezisebenzisa umbane ophezulu zihlala zine-conductor, inkqubo yokukhusela, isakhiwo sokukhusela, isakhiwo sokuthintela amanzi, umaleko wokukhusela kunye nesheath yangaphandle. Ukuhambelana kokusebenza kwezinto kumaleko ngamnye kuchaphazela ngokuthe ngqo ukhuseleko kunye nobomi benkonzo yentambo.
Inkqubo yoMqhubi kunye neyokugquma
I-conductor ngokubanzi yenziwe ngezinto zobhedu okanye ze-aluminium ezicocekileyo kakhulu. Ukunciphisa impembelelo yesikhumba kwi-AC transmission, iintambo ezinkulu ezinqamlezileyo zihlala zisebenzisa izakhiwo ze-conductor ezixineneyo okanye ezihlukaniswe ngokwezigaba ukuze ziphucule usasazo lwangoku kunye nokunciphisa ilahleko.
Izinto eziphambili zenkqubo yokukhusela ubushushu yiI-XLPE(I-Cross-linked Polyethylene Insulation Compound), ene-insulation esebenzayo yombane, ukumelana kakuhle nokuguga kobushushu kunye nobushushu obuphezulu obusebenzayo obuqhubekayo, nto leyo eyenza ukuba isetyenziswe kakhulu kwiintambo zamandla ze-voltage ephezulu kunye nee-voltage eziphezulu.
I-Semi-Conductive Shielding Compound idla ngokwenziwa ngaphandle komqhubi ukuze ilungelelanise ukusasazwa kwentsimi yombane, inciphise uxinano lwentsimi yombane kwaye inciphise umngcipheko wokukhutshwa okungaphelelanga, ngaloo ndlela iphucula uzinzo lwexesha elide lwenkqubo yokukhusela umbane.
Ukhuselo, Ukuvalwa kwamanzi kunye nolwakhiwo lwezixhobo
Umaleko wokukhusela wesinyithi udla ngokusebenzisa iteyiphu yobhedu okanye isakhiwo socingo lobhedu ukuze usasazeke ngendlela efanayo kwindawo yombane kwaye unikeze indlela ethembekileyo yokumisa umhlaba. Ukufana kobukhulu, imeko yomphezulu kunye nokuqhubekeka kokusebenza kweteyiphu yobhedu kuchaphazela ngokuthe ngqo umgangatho wokwakheka komaleko wokukhusela kunye nozinzo lwemveliso.
Ukuphucula ukuthembeka kwexesha elide kweentambo kwiindawo zokungcwaba ngqo okanye kwiindawo ezinomswakama ophezulu,Iteyiphu Yokuvimba Amanzikunye neWater Blocking Yarn zihlala zisetyenziselwa ukuthintela ukufuduka komswakama ngaphakathi kwintambo.
Kwiindawo ezisetyenziswayo ezinoxinzelelo olukhulu loomatshini, iintambo zamandla ezisebenza ngombane ophezulu zihlala zibonelelwa ngomaleko wokukhusela ukuphucula ucinezelo kunye nokumelana nempembelelo. Izinto eziqhelekileyo ziquka iGalvanized Steel Tape kunye neGalvanized Steel Wire Strand. Uzinzo lwazo olunemilinganiselo kunye nokukwazi ukucutshungulwa zichaphazela ukusebenza kwe-armor okulandelayo kunye nokuqhubeka kwemveliso.
Isingxobo sangaphandle
Isingxobo sangaphandle sisetyenziselwa ukhuseleko lwangaphandle lwentambo, ikakhulu sibonelela ngokumelana nokufuma, ukumelana nokugqwala kunye nokumelana noxinzelelo lokusingqongileyo. Izinto eziqhelekileyo ziquka iPVC Compound, iPE Sheath Material kunye neLSZH (Low Smoke Zero Halogen Sheath Material).
Phakathi kwezi, izinto ze-LSZH zisetyenziswa kakhulu kwiindlela zokuthutha oololiwe, amaziko edatha kunye nezakhiwo zikawonke-wonke ezineemfuno eziphezulu zokhuseleko lomlilo ngenxa yokuba zinomsi omncinci, azina-halogen kwaye azinawo amandla okuthintela ilangatye.
Njengomthengisi wezinto zekhebula, i-ONE WORLD inokubonelela ngezinto ezahlukeneyo ezinxulumene neentambo ze-voltage ephezulu, kubandakanya i-XLPE insulation compound, i-semi-conductive shielding compound, i-copper tape, i-water blocking tape, i-galvanized steel tape, i-galvanized steel wire strand kunye ne-sheathing compounds.
3. Kutheni Izinto Zentambo Zibaluleke Kangaka?
Ukusebenza kweentambo zamandla ezisebenza ngombane ophezulu akuxhomekekanga kuphela kuyilo lwesakhiwo kodwa nakwindlela ezihambelana ngayo izinto ezahlukeneyo. Ukusuka kwi-XLPE insulation compound ukuya kumaleko okukhusela iteyipu yobhedu, ukuya kwiteyipu yokuvimba amanzi, iteyipu yentsimbi egalelweyo kunye nezinto zokugquma, into nganye ichaphazela ukusebenza kwe-insulation yombane, amandla okukhusela oomatshini kunye nokuzinza kwexesha elide kwentambo.
Kwangaxeshanye, ukuzinza kwenkqubo yezinto ngexesha lokusonga ixesha elide, ukukhulula, ukubopha kunye nokukhupha izinto kuchaphazela ngokuthe ngqo ukusebenza kakuhle kwemveliso kunye nokuhambelana kwemveliso. Ke ngoko, ukuqhubekeka kokusebenza kwezinto kwiindawo zokwenziwa zokwenyani kuya kuxatyiswa ngakumbi ngabavelisi beentambo.
4. Iindlela zoPhuhliso lweeNtambo zoMbane zeVolthi ephezulu
Kwixesha elizayo, iintambo zamandla ezisebenzisa umbane ophezulu ziya kuqhubeka ziphuhlisa ukusebenza okuphezulu, ukuba nobuhlobo nokusingqongileyo kunye nobukrelekrele. Iikhompawundi zokukhusela ze-XLPE ezisebenzayo kakhulu, iikhompawundi ze-LSZH sheathing ezinobuhlobo nokusingqongileyo, kunye nezixhobo zokuthintela amanzi ezizinzileyo kunye nezixhobo zokukhusela ziya kuhlangabezana neemfuno zamandla avuselelekayo, ukuphuculwa kwegridi kunye nokusetyenziswa okuntsonkothileyo kokusingqongileyo.
Ngophuhliso lweegridi ezikrelekrele, ukujonga imeko yekhebula kunye nobuchwepheshe bokulumkisa kwangethuba kuya kwamkelwa kancinci kancinci. Izixhobo eziphambili zekhebula eziquka iteyiphu yobhedu, iteyiphu yokuthintela amanzi, iteyiphu yentsimbi egayiweyo kunye ne-XLPE insulation compound ziya kuqhubeka nokuphucula ukhuseleko, ukuthembeka kunye nokuzinza kwenkqubo yeentambo zamandla eziphezulu.
