Inzuzo yemveliso
I-Aluminium Alloy Stranded Wire eneCores yentsimbi: Eyona ndlela ikhethwayo yokudlulisela umbane
Kwimigca yombane ephezu komhlaba, ucingo olunentsimbi olune-aluminium alloy stranded lubonakala njengesisombululo esifanelekileyo kwiiprojekthi zokuhambisa umbane kunye nokusasazwa kombane, ngenxa yeenzuzo zalo ezimbini "zokuqina okuphezulu + ukuqhuba kakuhle kombane," okubonelela ngenkxaso engundoqo ezinzileyo, esebenzayo, nehlala ixesha elide yokuhambisa umbane.
1. Umxube Ogqibeleleyo Wokuqina Nokuqina Kweendawo Ezinzima
- Njengoko iingcingo zentsimbi ezinamandla aphezulu zingundoqo, umqhubi unamandla okutyhafa angaqhelekanga kunye nokumelana nokudinwa, kulula ukumelana neemeko ezinzima ezifana nokuwela ixesha elide, imimoya enamandla, kunye nomkhenkce/ikhephu. Inciphisa imiba yokuwa kwemigca, inciphisa ubunzima bokumiswa kunye nokugcinwa.
- Imicu ye-aluminium yangaphandle idibanisa ukuqina kwesinyithi kunye nokuzinza kwesakhiwo, inika ukumelana nokugqwala okuphezulu kunye nokumelana nokuguga. Oku kwandisa ubomi benkonzo yomqhubi kwaye kunciphisa iindleko zokusebenza zexesha elide.
2. Ukuqhuba kakuhle kakhulu ukuze kusebenze kakuhle kakhulu ekudluliseleni
Izinto ze-aluminium alloy zigcina umbane usondele kwi-aluminium ecocekileyo ngelixa ziqinisekisa amandla. Xa kuthelekiswa nemicu ye-aluminium yesiqhelo enentsimbi, zonyusa amandla okuthwala umbane phantsi kwecandelo elifanayo, zinciphisa ilahleko yomgca, kwaye zivumela ukudluliselwa kwamandla okusebenzayo nokonga amandla—zilungele iinethiwekhi zomgama omde eziphakathi neziphezulu.
Isicelo semveliso
Iikhontraktha ze-aluminium ezine-cored zentsimbi: Eyona nto iphambili ekudlulisweni kwamandla kwiimeko ezahlukeneyo
Ngenxa yeenzuzo zayo ezidibeneyo "zokomelela okuphezulu, ukuqhuba kakuhle kombane, kunye nokumelana nokusingqongileyo," ii-conductors ze-aluminium alloy ezine-steel-core zisebenza njengomdlali ophambili ekudluliseleni umbane kwiindawo ezininzi, zibonelela ngezisombululo ezenzelwe iimeko ezahlukeneyo.
1. Ukhetho oluPhambili lweMigca yoThumelo oluPhakathi noluPhezulu
Kwinethiwekhi eziphakathi kunye neziphezulu ze-110kV ukuya kwi-500kV, ii-conductors ze-aluminium alloy ezinentsimbi zigqwesile njenge "imithambo ephambili" edibanisa izitishi ezincinci kunye neegridi zengingqi. Ingakumbi kwiindawo ezingqonge izixeko kunye neendawo ezisemaphandleni, ziyaziqhelanisa neemfuno zocingo ezintsonkothileyo kwiindawo ezinabantu abaninzi, zilungelelanisa ukusebenza kakuhle kothumelo kunye nokhuseleko kunye nozinzo.
2. Inkxaso Ethembekileyo Yeendlela Ezinqamlezileyo Zokunqumla Iinqwelwana Ezinde
Xa kudlula imiqobo yendalo (imilambo, iintlambo, iintaba) okanye iindlela zothutho ezibalulekileyo (iindlela ezinkulu, oololiwe), amandla aphezulu ezi zixhobo zokuqhuba anciphisa imfuneko yee-pylon ezigqithisileyo, anciphisa imiba yokuwa ebangelwa zii-span ezinde, kwaye aqinisekise ukusebenza okuzinzileyo phantsi kwemimoya enamandla, ukuguquguquka kobushushu, kunye nezinye iimeko ezinzima. Zisetyenziswa kakhulu kwimigca yothumelo enqumla umlambo kunye neeprojekthi eziphezulu zeentaba.
3. Ukuphuculwa kunye nokuhlaziywa kweeGridi zoMbane zasezidolophini nezaseMaphandleni
Kwiiprojekthi ezibandakanya ukuhlaziywa kweegridi ezidala okanye ukwandiswa komthamo kwiindawo zasezidolophini nezasemaphandleni, uyilo lwazo olukhaphukhaphu lwenza kube lula ukwakhiwa nokufakelwa kwakhona. Ukongeza, ukumelana kwazo nokugqwala nokuguga kunciphisa iimfuno zolondolozo lwexesha elide, nto leyo ezenza zibe zilungele iindawo ezinzima ezifana neendawo zasemaphandleni ezinothuli, imimandla efumileyo, kunye neendawo ezikunxweme ezinetyuwa eninzi—ukuphucula ukusebenza kakuhle kwegridi.
