Ikhebula lokudonsa libizwa nangokuthi ikhebula lokudonsa elimise okwesitsha (yezintambo zasendlini), okuwukubeka iyunithi yokuxhumana optical (fiber optical) phakathi nendawo, bese ibeka amalungu amabili ahambisanayo angewona ezensimbi (FRP) noma amalungu okuqinisa insimbi. nhlangothi zombili.Okokugcina, kukhishwe okumnyama noma okumhlophe , i-polyvinyl chloride empunga (PVC) noma into engenantuthu ephansi ye-halogen (LSZH, intuthu ephansi, i-halogen-free, i-flame retardant).Ikhebuli yokudonsa yangaphandle inocingo olulengayo oluzisekelayo olumumo we-figure-8.
Ikhebula lokudonsa livame ukuhlukaniswa libe core 1, 2 cores kanye 4 cores single-mode fibre optic cable.Ngokuvamile, ingqikithi eyodwa isetshenziselwa ukudluliswa kwedatha yasendlini, futhi ama-cores angu-2 asetshenziselwa umsakazo, umabonakude, i-cable TV kanye ne-broadband.
imicu ye-cable optical fibers ngokuvamile ihlanganisa i-G657A2 optical fibers, i-G657A1 optical fibers, kanye ne-G652D optical fibers.Kunezinhlobo ezimbili zokuqiniswa okumaphakathi, iziqinisi zensimbi kanye neziqinisekiso ezingezona ezensimbi ze-FRP.Iziqinisekiso zensimbi zihlanganisa ① intambo yensimbi ephosphating ② intambo yensimbi yethusi ③ intambo yensimbi egayiwe ④ intambo yensimbi enamathiselwe (okuhlanganisa i-phosphated steel wire kanye ne-galvanized steel wire eneglue).Ukuqiniswa okungekona okwensimbi kufaka phakathi ①GFRP②KFRP③QFRP.
Umgodla wekhebula lokudonsa ngokuvamile umhlophe, umnyama, futhi umpunga.Okumhlophe kuvame ukusetshenziswa endlini, kanti okumnyama kusetshenziswa ngaphandle, okungazweli e-UV futhi nemvula.Impahla ye-sheath ifaka i-PVC polyvinyl chloride kanye ne-LSZH yentuthu ephansi ye-halogen-free retardant sheath material.Ngokuvamile, abakhiqizi bahlukanisa izindinganiso ze-LSZH ze-halogen-free flame retardant zibe izinhlobo ezintathu: i-non-flame retardant, i-flame retardant yokuvutha eqondile eyodwa, ne-bundle flame retardant.
Imigqa yokumiswa kwekhebula yangaphandle ngokuvamile ikwazi ukuzisekela ngamamitha angu-30-50.I-Phosphating steel wire ithatha u-0.8-1.0MM, intambo yensimbi eyakhiwe ngothayela, intambo yensimbi enamathiselwe.
Izici zekhebula lokudonsa: i-fiber optical ekhethekile engagobile, ehlinzeka ngomkhawulokudonsa omkhulu futhi ithuthukisa ukusebenza kokudluliswa kwenethiwekhi;ama-FRP amabili afanayo noma ama-metal reinforcements enza ikhebula le-optical libe nokusebenza okuhle kokucindezela futhi livikele i-fiber optical;ikhebula le-optical linesakhiwo esilula, isisindo esilula, nokusebenza okunamandla Okunamandla;umklamo oyingqayizivele we-groove, ukucwecwa okulula, uxhumano olulula, ukufakwa nokugcinwa lula;intuthu ephansi ye-halogen yamahhala ye-polyethylene emgodleni we-flame retardant noma umgodla we-PVC we-flame retardant, ukuvikelwa kwemvelo.Ingafaniswa nezinhlobonhlobo zezixhumi zensimu futhi inganqanyulwa.
Ngenxa yokuthambile nokukhanya kwayo, ikhebula lokudonsa lisetshenziswa kabanzi kunethiwekhi yokufinyelela;igama lesayensi lekhebula lokudonsa: ikhebula lomthofu elimise okwevemvane lokufinyelela inethiwekhi;ngenxa yesimo sovemvane, libuye libizwe ngekhebula le-butterfly, ikhebula le-Figure 8.Umkhiqizo usetshenziswa ku: isetshenziselwa izintambo zasendlini, ikhebula eliqondile elisetshenziswa abasebenzisi bokugcina;esetshenziselwa ukwethula izintambo zokukhanya ezakhiweni;isetshenziselwa izintambo zangaphakathi zabasebenzisi ku-FTTH.
