1. Ucingo lwentsimbi
Ukuze kuqinisekiswe ukuba intambo inokumelana noxinzelelo lwe-axial olwaneleyo xa ibekwa kwaye isetyenziswa, intambo kufuneka ibe nezinto ezinokuthwala umthwalo, isinyithi, okanye isinyithi, xa kusetyenziswa ucingo lwentsimbi olunamandla aphezulu njengenxalenye yokuqinisa, ukuze intambo ibe nokumelana okuhle koxinzelelo lwecala, ukumelana nempembelelo, ucingo lwentsimbi lukwasetyenziselwa intambo phakathi kwe-sheath yangaphakathi kunye ne-sheath yangaphandle yezixhobo. Ngokwesiqulatho sayo sekhabhoni, ingahlulwa ibe yi-wire yentsimbi enekhabhoni ephezulu kunye ne-wire yentsimbi enekhabhoni ephantsi.
(1) Ucingo lwentsimbi yekhabhoni ephezulu
Intsimbi yentsimbi yekhabhoni ephezulu kufuneka ihlangabezane neemfuno zobugcisa ze-GB699 carbon steel esemgangathweni ophezulu, umxholo wesalfure kunye ne-phosphorus umalunga ne-0.03%, ngokwendlela yonyango eyahlukileyo yomphezulu ingahlulwahlulwa ibe yintsimbi yentsimbi egalelweyo kunye nentsimbi ye-phosphating. Intsimbi yentsimbi egalelweyo ifuna ukuba umaleko we-zinc ufane, uthambe, unamathele ngokuqinileyo, umphezulu wentsimbi yentsimbi kufuneka ucoceke, ungabi naoyile, ungabi namanzi, ungabi namabala; Umaleko we-phosphating wentambo ye-phosphating kufuneka ufane kwaye ukhanye, kwaye umphezulu wentambo kufuneka ungabi naoyile, amanzi, amabala omhlwa kunye nemivumbo. Ngenxa yokuba ubungakanani bokuguquka kwe-hydrogen buncinci, ukusetyenziswa kwentambo yentsimbi ye-phosphating kuxhaphake kakhulu ngoku.
(2) Ucingo lwentsimbi olunekhabhoni ephantsi
Ucingo lwentsimbi olunekhabhoni ephantsi lusetyenziswa ngokubanzi kwintambo exhonyiweyo, umphezulu wocingo lwentsimbi kufuneka ugqunywe ngomaleko we-zinc ofanayo noqhubekayo, umaleko we-zinc akufuneki ube neentanda, iimpawu, emva kovavanyo lokujika, akufuneki kubekho iminwe engenanto enokucima ukuqhekeka, i-lamination kunye nokuwa.
2. Umsonto wentsimbi
Ngophuhliso lwentambo ukuya kwinani elikhulu elingundoqo, ubunzima bentambo buyanda, kwaye uxinzelelo ekufuneka luthwalwe luqiniswe luyanda. Ukuze kuphuculwe amandla entambo ye-optical yokuthwala umthwalo kwaye imelane noxinzelelo lwe-axial olunokuthi lwenziwe ekubekweni nasekusetyenzisweni kwentambo ye-optical, intambo yentsimbi njengenxalenye yokuqinisa yentambo ye-optical yeyona ifanelekileyo, kwaye inokuguquguquka okuthile. Intambo yentsimbi yenziwe ngemicu emininzi yokujija ucingo lwentsimbi, ngokwesakhiwo secandelo ngokubanzi inokwahlulwahlulwa ibe yi-1 × 3,1 × 7,1 × 19 iintlobo ezintathu. Uqiniso lwentambo ludla ngokusebenzisa intambo yentsimbi eyi-1 × 7, intambo yentsimbi ngokwendlela amandla okutsalwa aqhelekileyo ahlulwe abe yi: 175, 1270, 1370, 1470 kunye ne-1570MPa amabakala amahlanu, imodulus ye-elastic yentambo yentsimbi kufuneka ibe ngaphezulu kwe-180GPa. Intsimbi esetyenziselwa umsonto wentsimbi kufuneka ihlangabezane neemfuno ze-GB699 “Iimeko zobugcisa zesakhiwo sentsimbi yekhabhoni esemgangathweni ophezulu”, kwaye umphezulu wocingo lwentsimbi olugqunyiweyo olusetyenziselwa umsonto wentsimbi kufuneka ugqunywe ngomaleko ofanayo noqhubekayo we-zinc, kwaye akufuneki kubekho amabala, imifantu kunye neendawo ezingenayo i-zinc plating. Ububanzi kunye nomgama wentambo yomsonto ziyafana, kwaye akufuneki zikhululeke emva kokusikwa, kwaye ucingo lwentsimbi lomsonto kufuneka ludityaniswe ngokusondeleyo, ngaphandle kokuqhekeka, ukwaphuka kunye nokugoba.
3.I-FRP
I-FRP sisifinyezo soonobumba bokuqala beplastiki eqinisiweyo yefayibha yesiNgesi, esisixhobo esingesisinyithi esinomphezulu ogudileyo kunye nobubanzi obufanayo bangaphandle obufunyenwe ngokugquma umphezulu wemicu emininzi yefayibha yeglasi nge-resin yokukhanya, kwaye idlala indima yokuqinisa kwintambo ye-optical. Ekubeni i-FRP iyinto engesisinyithi, inezi nzuzo zilandelayo xa ithelekiswa nokuqinisa isinyithi: (1) Izinto ezingesisinyithi azinangxaki kumothuko wombane, kwaye intambo ye-optical ifanelekile kwiindawo zombane; (2) I-FRP ayivelisi impendulo ye-electrochemical ngokufuma, ayivelisi iigesi eziyingozi kunye nezinye izinto, kwaye ifanelekile kwiindawo ezinemvula, ezishushu nezinomswakama; (3) ayivelisi umsinga we-induction, inokubekwa kumgca we-high-voltage; (4) I-FRP ineempawu zobunzima obulula, obunokunciphisa kakhulu ubunzima bentambo. Umphezulu we-FRP kufuneka ube mtyibilizi, ukungabi nangqukuva kufuneka kube kuncinci, ububanzi kufuneka bufane, kwaye akufuneki kubekho i-joint kubude bediski eqhelekileyo.
4. I-Aramid
I-Aramid (i-polyp-benzoyl amide fiber) luhlobo lwefayibha ekhethekileyo enamandla aphezulu kunye ne-modulus ephezulu. Yenziwe nge-p-aminobenzoic acid njenge-monomer, xa kukho i-catalyst, kwinkqubo ye-NMP-LiCl, nge-solution condensation polymerization, kwaye emva koko nge-wet spinning kunye ne-high tension heat treatment. Okwangoku, iimveliso ezisetyenziswayo ikakhulu yimodeli yemveliso i-KEVLAR49 eveliswe yiDuPont eMelika kunye nemodeli yemveliso iTwaron eveliswe yi-Akzonobel eNetherlands. Ngenxa yokumelana kwayo nobushushu obuphezulu kunye nokumelana ne-thermal oxidation, isetyenziswa ekwenzeni i-all-medium self-supporting cable reinforcement (ADSS).
5. Intambo yefayibha yeglasi
Intambo yefayibha yeglasi yinto engeyoyesinyithi esetyenziswa rhoqo ekuqiniseni intambo ye-optical, eyenziwe ngemicu emininzi yefayibha yeglasi. Inokumelana okuhle kakhulu nokugqwala, kunye namandla aphezulu okutsalwa kunye nokuguquguquka okuphantsi, okwenza ukuba ilungele ukuqinisa okungeyosinyithi kwiintambo ze-optical. Xa kuthelekiswa nezinto zesinyithi, intambo yefayibha yeglasi ilula kwaye ayivelisi umbane oshukunyiswayo, ngoko ke ifanelekile ngakumbi kwimigca ye-voltage ephezulu kunye nokusetyenziswa kwentambo ye-optical kwiindawo ezimanzi. Ukongeza, intambo yefayibha yeglasi ibonisa ukumelana okuhle kokuguguleka kunye nokumelana nemozulu xa isetyenziswa, iqinisekisa uzinzo lwexesha elide lwentambo kwiindawo ezahlukeneyo.
