iintambo ezigqunyiweyo (kubandakanywa iintambo ze-AC kunye ne-DC, iintambo zomhlaba kunye neentambo zangaphantsi kwamanzi) ngokwemigangatho ephucukileyo kunye neenkcukacha ekhaya nakwamanye amazwe, kunye

igqibe imisebenzi emininzi yokubhaqa kunye nokuvavanya kubasebenzisi abaninzi ekhaya naphesheya, ngowona mandla ombane aphezulu angama-± 550kV.

Ummeli ongentla omele iintambo zamandla ombane aphezulu kakhulu kunye nezincedisi kunye nezicelo zabo zobunjineli zibonisa ngokupheleleyo ukuba ishishini lentambo laseTshayina likumazwe ngamazwe.

inqanaba eliphezulu ngokubhekiselele kwi-innovation yobugcisa, inqanaba lobugcisa, umthamo wokuvelisa, uvavanyo kunye novavanyo kulo mmandla.

Umzi-mveliso "Iimbambo ezithambileyo" kunye "neeNtsilelo"

Nangona ishishini lentambo lenze inkqubela phambili enkulu kunye nempumelelo egqwesileyo kule ntsimi kwiminyaka yakutshanje, kukwakho “ubuthathaka” obubalaseleyo.

okanye “iimbambo ezithambileyo” kulo mmandla.Obu “buthathaka” bufuna ukuba senze iinzame ezinkulu ukuze silungise izinto ezintsha, nto leyo ekwasisikhokelo kunye nenjongo

iinzame eziqhubekayo kunye nophuhliso.Uhlalutyo olufutshane lulandelayo.

(1) Iintambo ezigqunyiweyo ze-EHV XLPE (kubandakanywa neentambo ze-AC kunye ne-DC, iintambo zomhlaba kunye neentambo zasemanzini)

"Umbambo othambileyo" obalaseleyo kukuba izinto zokugquma ezicoceke kakhulu kunye nezixhobo zokukhusela ezigudileyo zingeniswa ngaphandle ngokupheleleyo, kubandakanywa ukugquma.

kunye nezixhobo zokukhusela ezi projekthi zinkulu zingentla.Le "yingxaki" ebalulekileyo ekufuneka igqobhoze.

(2) Izixhobo ezingundoqo zokuvelisa ezisetyenziswa ekwenzeni iintambo zombane ezigqunywe nge-polyethylene ezigqunywe ngamandla ombane aphezulu.

Okwangoku, zonke zithunyelwa ngaphandle kwamanye amazwe, enye "ibambo elithambileyo" loshishino.Okwangoku, inkqubela enkulu esiyenzileyo kwintsimi ye

Iintambo zamandla ombane we-ultra-high ikakhulu "ziyalungiswa" kunokuba "zokudala", kuba izixhobo eziphambili kunye nezixhobo eziphambili zisaxhomekeke kumazwe angaphandle.

(3) Intambo yombane ephezulu kunye nokusetyenziswa kwayo kwezobunjineli

Ezi ntambo zombane ziphezulu kakhulu kunye nokusetyenziswa kwazo kwezobunjineli zimele elona nqanaba lilungileyo kwithafa lentambo yentambo yombane wombane ophezulu waseTshayina, kodwa hayi inqanaba lethu lilonke.

Inqanaba elipheleleyo lentsimi yentambo yamandla ayiphezulu, ekwayenye yezona "ziibhodi ezimfutshane" eziphambili zeshishini.Kukho nezinye ezininzi "iibhodi ezimfutshane" kunye

amakhonkco abuthathaka, afana nala: uphando olusisiseko kwiintambo zombane eziphezulu ze-voltage kunye ne-ultra-high kunye neenkqubo zazo, itekhnoloji ye-synthesis kunye nezixhobo zenkqubo yococeko olukhulu.

i-resin, uzinzo lokusebenza kwezixhobo zasekhaya eziphakathi kunye nophezulu ombane wentambo, amandla okuxhasa ishishini kubandakanya izixhobo ezisisiseko, amacandelo kunye

izinto ezincedisayo, ukuthembeka kwenkonzo yexesha elide yeentambo, njl.

Ezi "imbambo ezithambileyo" kunye "nobuthathaka" ziyimiqobo kunye nemiqobo yokuba iChina ibe lilizwe elinamandla entambo, kodwa ikwayisikhokelo kwiinzame zethu

yoyise imiqobo kwaye uqhubeke nokusungula izinto ezintsha.
