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 eneglu). 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. Ngokubanzi, abavelisi bohlula i-LSZH imigangatho ye-halogen-free flame retardant ephantsi ibe ziindidi ezintathu: i-non-flame retardant, i-flame retardant eyodwa ethe nkqo, 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.
