Intambo yokulahla ikwabizwa ngokuba yintambo yokulahla isitya-ezimilise (kwi-wiring yangaphakathi), oku ukubeka iyunithi yonxibelelwano optical (ifayibha optical) embindini, kwaye ubeke amalungu amabini ahambelanayo angeyontsimbi yokuqinisa (FRP) okanye amalungu okuqinisa isinyithi. macala omabini.Okokugqibela, extruded emnyama okanye emhlophe , grey polyvinyl chloride (PVC) okanye umsi ophantsi halogen-free izinto (LSZH, umsi ophantsi, halogen-free, ilangatye retardant) sheathed.Intambo yokulahla yangaphandle ine-self-supporting wire ejingayo kwi-figure-8 shape.
Intambo yokulahla yahlulwe ngokubanzi ibe yi-1 core, 2 cores kunye ne-4 cores enye-mode yefiber optic cable.Ngokuqhelekileyo, i-core eyodwa isetyenziselwa ukuhanjiswa kwedatha yendlu, kwaye i-2 cores isetyenziselwa irediyo, ithelevishini, i-cable TV kunye ne-broadband.
ukulahla i-cable optical fibers ngokubanzi iquka i-G657A2 i-optical fibers, i-G657A1 i-fibers optical, kunye ne-G652D i-optical fibers.Kukho iindidi ezimbini zokuqiniswa okuphakathi, ukuqiniswa kwesinyithi kunye ne-non-metallic FRP reinforcements.Iziqinisekiso zentsimbi ziquka ① ucingo lwentsimbi ephosphating ② ucingo lwentsimbi yobhedu ③ ucingo lwentsimbi ④ oludityanisiweyo lwentsimbi (kuquka ucingo lwentsimbi enefosfati kunye nocingo lwentsimbi oluneglu).Iziqinisekiso ezingezizo ezentsimbi ziquka ①GFRP②KFRP③QFRP.
I-sheath yentambo yokulahla ngokubanzi imhlophe, imnyama, kunye nengwevu.Imhlophe iqhele ukusetyenziswa ngaphakathi endlini, kwaye emnyama isetyenziswa ngaphandle, into ekwaziyo ukumelana ne-UV kunye nemvula.Izinto ze-sheath ziquka i-PVC ye-polyvinyl chloride kunye ne-LSZH ephantsi komsi we-halogen-free flame retardant sheath material.Ngokuqhelekileyo, abavelisi bahlula imigangatho ye-LSZH ephantsi kwe-halogen-free flame retardant ibe ziindidi ezintathu: i-non-flame retardant, i-flame retardant edibeneyo yokutshisa enye, kunye ne-bundle flame retardant.
Imigca yokunqunyanyiswa kwentambo yangaphandle iyakwazi ukuzixhasa ngeemitha ezingama-30-50.I-Phosphating steel wire ithatha i-0.8-1.0MM, i-galvanized steel wire, i-glued steel wire.
Iimpawu zentambo yokulahla: i-fiber optical egoba ekhethekileyo, ebonelela nge-bandwidth enkulu kunye nokuphucula ukusebenza kothumelo lwenethiwekhi;I-FRP ezimbini ezihambelanayo okanye i-metal reinforcements yenza i-cable optical ibe nokusebenza kakuhle koxinzelelo kunye nokukhusela i-fiber optical;intambo ye-optical inesakhiwo esilula, ubunzima obulula, kunye nokusebenza okunamandla;uyilo olulodwa lwegroove, kulula ukuyixobula, uqhagamshelo olulula, ukufakwa kunye nokugcinwa lula;Umsi ophantsi we-halogen okhululekileyo we-polyethylene retardant sheath okanye i-flame retardant PVC sheath, ukhuseleko lokusingqongileyo.Inokudityaniswa neentlobo ngeentlobo zezihlanganisi zentsimi kwaye inokupheliswa intsimi.
Ngenxa yokuthambile kwayo kunye nokukhanya, ikhebula lokulahla lisetyenziswa ngokubanzi kwinethiwekhi yokufikelela;igama lenzululwazi lentambo yokulahla: intambo yebhabhathane emile okwebhathane yokufikelela kuthungelwano;ngenxa yokumila kwebhabhathane, ikwabizwa ngokuba yintambo yebhabhathane, iFigure 8 cable.Imveliso isetyenziselwa: isetyenziselwa i-wiring yangaphakathi, ikhebula elithe ngqo elisetyenziswe ngabasebenzisi bokugqibela;esetyenziselwa ukwazisa iintambo zokukhanya kwizakhiwo;isetyenziselwa ukwenza iintambo zangaphakathi zabasebenzisi kwi-FTTH.
