Imiqhubi Yekhanda Lokufaka Umthelelo Osobala yingxenye ebalulekile ekwakheni iindawo zokuthutha kwamandla nezinye iisubstations. Imfuneko yabo eyenzululwane yiya kuqeda ngokuphindwe kabini: ukunika ukuqeda kwezimali phakade phakathi kwezihlwe bosemthethweni nezihlwe ezimiselwe, nokholwa kumandla amakhulu kusukela kummandla wozililo, umoya, nesibindi. Ukukhetha nokulinganisa kwezi ziqhubi ngexesha lokufakwa kuyadinga imikhawulo emandla, ubomi obubi, nokuchaphazela izindleko zokuhlengahlenga komthetho osobala wonke. KHebei Heiniu, siyayisebenza ekwenzeni i-composite (ezingaphantsi) iziqhubi ezihlale ziyafundwa yizinto ezintsha njengoko zibaluleke kakhulu, zenzelelanayo, nokholwa kwazo okungaphezulu.
Isahluko sesixeko sethu sisikhombisi esinamandla okwenzelwa nge-Fiber Reinforced Polymer (FRP), esenzelwa kwiwori wethu onjalo. Akuyona into efakwa njalo; sithuthukisa isinhloko sezindiza nezinhloko zezihlwire, ukufakelwa kwesilonda ukuze siyifinyelele amandla okugcina nemisebenzi yamandla. Kumele isikhombisi sine-amandla aphezulu ekususweni kwizinto ezindele ukuthutha izihlwire eziphakeme kakhulu, inzuzo yokungabi namandla ekuvikeleni kwizivivino, futhi, ngokuphathelene kakhulu, inzuzo ephezulu ekungabikeni ngendlela ethambile futhi ekungabikeni ngendlela engaqede kangaka. Lokhu kuyincoma yokubamba umthombo wesixeko kwaye kumele kube khona ngeminyakeni engaphezu kwe-20, lokho akudingeki kuba khona ngaphandle kwezixazululo zomthombo onjalo. Ngaphandle kwalokho kukhona umbutho nokusheda okwenzelwa ngesilicone rubber enobuhlobo obuphezulu. Ukushesha kukaqala kukaqala, lo mbutho uphindele umfanekiso opholile oshayiselwa yizimali, into entsha ekubalulekile ukubamba ubunzima bomthelelo emanzini ahlukene noma uma kumshiswa, lokho kungase kube khona ngexesha lokwakha.
Ngaphandle kakhulu Imiqhubi Yekhanda Lokufaka Umthelelo Osobala , umlenze phakathi kwegogo ye-FRP nezidingo zemetali ziphumelelo kungumlando wokulungiswa. Siyisebenzisa isiphindukulo samandla angcono nokusekelwa kwamandla amathuba ukwakha ukuqoshwa okudala, okugcwele. Lokhu kusekelwa kwenziwa kwasimiso seteknoloji yethu, kuchazwe ngokuphelele ukuthi akuvunyiwe nge-moisture, okuyisahluko ekhona kakhulu kokucindezelwa kangenhlane kanye nokuhluka kwesithixo. Izidingo zemetali zonke, ezenziwa kanye nezihlengalenga ezikhishini zethu, zenzelwe ukuthi zixhunye ngempela kanye ngokuphelele kwe-tower yokesi noma i-conductor hardware, ukunciphisa kanye nokuphelele kwezibhamu zokufaka. Iyephansi yazo ihlinzekwa ngemviko eyaphucayo yokulahleka, njenge-hot-dip galvanizing, ukuthutha kwekholo lezimali kusuku lwokuqala emhlabeni.
Izinkinga zokukhetha izilavu zeHeiniu zesilika sangaphandle kwezimali ziningi. Ubuncane bawo—ngaphezu kuka-70-90% ubuncane kungeza okulinganayo kwezindiza—kuyisiphaphalozo esikhulu ekulondolozweni nokuphatha. Kuvumela ukuthuthana kakhulu kuzindawo ezingaphandle, kususa amandla okuthuthana okudingekayo, kususa ububi bokusebenza kwabasebenzi, kanye nokushisa kakhulu kwemfundo yokudonsa nokufaka. Lokhu kugcina ngqo kususa izindleko zokakha kanye nezinyanga ezimbalwa zomthetho. Ngaphezu koko, ubuchule bempilo bempilo nombophongo wabo obungcono kuvikela umugqa omusha ukuba uphumelele kwi-indeks eyingqayizivele, noma kube nzima izindleko zokuhlela ezodwa kulokho.
Amandla ethu okukhiqiza asenza sikwazi ukuhlinzeka ngemisebenzi eminingi yokufaka amandla aphezulu. Kungakhathaliseki ukuthi isidingo siwukuthi kube nama-suspension insulators egumbini elisha lokudlulisela i-230kV, ama-long-rod insulators emigqeni ye-HVDC, noma ama-station post insulators aqinile esiteshini esisha se-GIS, imodeli yethu yokukhiqiza ehlanganisiwe inikeza Sisebenzisana nonjiniyela bephrojekthi ukuze senze izixazululo ezifanele, siqinisekise ukuthi izihlanganisi zethu zihambisana nezidingo eziqondile zikagesi, ezomshini nezemvelo zephrojekthi ngayinye, sibeke isisekelo sokuphepha nokwethenjelwa okuyohlala izizukulwane ngezizukulwane.
