Izintambo ze-Indoor Optical zivame ukusetshenziswa ezinhlelweni ezihlelekile ze-Cabling. Ngenxa yezinto ezahlukahlukene ezifana nemvelo yokwakha kanye nezimo zokufaka, ukwakhiwa kwezintambo zamehlo zasendlini sekuyinkimbinkimbi kakhulu. Izinto ezisetshenziselwa imicu ye-optical fibers kanye nezintambo zihlukile, ngezindawo zemishini nezokukhanya zigcizelelwa ngokuhlukile. Izintambo ezijwayelekile ze-Indoor Indoor zifaka amakhebuli angokwesiko elilodwa, izintambo ezingahlanganisiwe, nezintambo ezihlanganisiwe. Namuhla, umhlaba munye uzogxila kwenye yezinhlobo ezivame kakhulu zezintambo ezi-optical ezihlanganisiwe: GJFJV.
Ikhebula le-GJFJV Indlu yekhebula
1. Ukwakheka okuhlelekile
Imodeli evamile yemboni yezintambo zamehlo zasendlini yi-GjFJV.
I-GJ - Imali yokuxhumana ye-Indoor Optical Cable
F - Isakhi sokuqinisa esingesihle
J - Isakhiwo se-File-Buffered Eptical Fiber
V - I-Polyvinyl Chloride (PVC) Sheath
QAPHELA: Okwe-Sheath Matering Ukuqanjwa Kwama-Sheath
2. Indlu ye-Indoor Cable Cross-Sec Diagam
Izinto zokwakheka nezici
1. I-fiber ye-Optical Fiber (eyakhiwe nge-fiber optical ne-external coating ungqimba)
I-fiber ye-optical yenziwa ngezinto ze-silica, futhi ububanzi obujwayelekile bokugcina buyi-125 μm. Ububanzi obuyisisekelo bemodi eyodwa (B1.3) buyi-8.6-9.5 μm, futhi ngemodi ehlukahlukene (om1 A1B) ngu-62.5 μm. Ububanzi obuyisisekelo bemodi ehlukahlukene OM2 (A1A.1), OM3 (A1A.2), OM4 (A1A.3), no-Om5 (A1A.4) ngu-50 μm.
Ngesikhathi senqubo yokudweba ye-Glass Optical fiber, ungqimba lwenhlanganisela ye-elastic lusetshenziswa kusetshenziswa ukukhanya kwe-ultraviolet ukuvikela ukungcoliswa ngothuli. Lokhu kuhlanganiswa kwenziwa ngezinto zokwakha ezifana ne-acrylate, i-alicone ruble, ne-nylon.
Umsebenzi we-coatis ukuvikela indawo ye-fiber ye-optical kusuka kumswakama, igesi, kanye ne-abrasion yemishini, kanye nokuthuthukisa ukusebenza kwe-microbend kwefayibha, ngaleyo ndlela kunciphise ukulahleka okwengeziwe kokugoba.
I-coating ingafakwa imibala ngesikhathi sokusetshenziswa, futhi imibala kufanele ivumelane ne-GB / T 6995.2 (eluhlaza okwesibhakabhaka, owolintshi, oluhlaza obomvu, omnyama, ophuzi, omhlophe, onsundu, ophuzi, ophuzi, ophuzi). Futhi kungahlala kungacaciswanga njengemvelo.
2.
Izinto zokwakha: Imvelo, i-Flame-Retardant Polyvinyl Chloride (PVC),I-HOLOCH SANCEACE HOLOGEN-Free (LSZH) Polyolofi, Ikhebula le-flame-retardant le-flame-retardant, ikhebula le-flame-rated-retardant.
Umsebenzi: Kubuye kuvikeleke imicu ye-optical, kuqinisekise ukuguquguquka kwabo ngezimo ezahlukahlukene zokufaka. Inikeza ukumelana nokungezwani, ukucindezela, nokugoba, futhi kunikeza nokumelana kwamanzi kanye nomswakama.
Sebenzisa: Isendlalelo se-buffer eqinile ingaba nemibala yokuhlonza, ngamakhodi wemibala avumelana namazinga we-GB / T 6995.2. Ngokukhonjwa okungeyona eyejwayelekile, izindandatho zombala noma amachashazi zingasetshenziswa.
I-3. Ukuqinisa kabusha izingxenye
Okubonakalayo:Intambo e-aramid, ngokuqondile i-poly (p-phenyene terephthalamide), uhlobo olusha lwe-fiber ephezulu yezobuchwepheshe. Inezakhiwo ezinhle kakhulu njengamandla e-Ultra-aphezulu, i-modulus ephezulu, ukumelana okuphezulu, i-acid ye-alkali, engasindi, ukufakwa, ukumelana nokuguga, kanye nempilo yenkonzo ende. Emazingeni okushisa aphezulu, kugcina ukuqina, okunesilinganiso esiphansi kakhulu se-shrinkage, amazinga aphansi aphansi, kanye nokushisa kwengilazi okuphezulu. Inikeza nokumelana okuphezulu kokugqwala nokungenzi lutho, okwenza kube yinto efanelekile yokuqiniswa kwezintambo ze-optical.
Umsebenzi: Intambo e-Aramid inamathele ngokulinganayo nxazonke noma ibekwe ende ekhebula ikhebula ukuhlinzeka ukwesekwa, ukuthuthukisa ukumelana nokucindezela kwentambo, amandla omshini, nokuqina okushisayo.
Lezi zici ziqinisekisa ukusebenza kwe-Cable ukuhambisa kanye nempilo yenkonzo. I-ARAMID nayo isetshenziswa kakhulu ekukhiqizweni kwama-bulletproof vests kanye namapharashu ngenxa yamandla ayo amahle kakhulu.
4. Umvini wangaphandle
Izinto zokwakha: Intuthu ephansi i-Falogen-Retardant Polyolofy (LSZH), i-polyvinyl chloride (pvc), noma i-flame-rated Ezinye izinto ze-sheath zingasetshenziswa njengezidingo zamakhasimende. Intuthu ephansi ye-halogen-free polyolovif kufanele ihlangabezane namazinga we-yd / t1113; I-Polyvinyl Chloride kufanele ihambisane ne-GB / T8815-2008 yezinto zokwenziwa ze-PVC ezithambile; I-Thermoplastic Polyurethane kufanele ihlangabezane namazinga we-YD / T3431-2018 ama-Thermoplastic polyurethane lastomers.
Umsebenzi: I-Outer Sheath inikeza isivikelo esingeziwe semicu ye-Optical, Ukuqinisekisa ukuthi bangazivumelanisa nezimo ezahlukahlukene zokufaka. Iphinde inikeze ukumelana nokungezwani, ukucindezela, nokugoba, ngenkathi kunikeza amanzi kanye nokumelana namanzi. Ngezimo zokuphepha ngomlilo eziphakeme, izinto eziphansi ze-halogen-free zisetshenziselwa ukuthuthukisa ukuphepha kwekhebula, ukuvikela abasebenzi kusuka kumagesi ayingozi, intuthu, namalangabi uma kwenzeka umlilo.
Sebenzisa: Umbala we-sheath kufanele uvumelane namazinga we-GB / T 6995.2. Uma i-Optical fiber inguhlobo lwe-B1.3-hlobo, umgoqo kufanele abe ophuzi; Nge-B6-TYPE, i-sheath kufanele ibe ophuzi noma iluhlaza; Ngokwe-AIA.1-TYPE, kufanele kube yiwolintshi; Uhlobo lwe-aib kufanele lube ngmpunga; I-A1A.2-TYPE kufanele ibe luhlaza okotshani; kanye ne-a1a.3-hlobo kufanele kube onsomi.
Izimo Zokusebenza
1. Isetshenziswa ngokujwayelekile ezinhlelweni zokuxhumana zangaphakathi ngaphakathi kwezakhiwo, njengamahhovisi, izibhedlela, izikole, izikhungo zezimali, izikhungo zedatha, njll. Isetshenziswa kakhulu ukuxhumana phakathi kwemishini nama-opharetha angaphandle. Ngokwengeziwe, izintambo zamehlo zangaphakathi zingasetshenziswa kwi-wiring yenethiwekhi yasekhaya, njenge-LANS kanye nezinhlelo ezihlakaniphile zasekhaya.
2. Ukusetshenziswa: Izintambo ze-Indoor Optical ziyi-compact, engasindi, ukonga isikhala, futhi kulula ukuyifaka nokuyigcina. Abasebenzisi bangakhetha izinhlobo ezahlukene zezintambo ze-Indoor Optical ezisuselwa kwizidingo ezithile zendawo.
Kumakhaya ajwayelekile noma izikhala zehhovisi, amakhebula ajwayelekile e-PVC angasetshenziswa.
Ngokusho kweNational Standard GB / T 51348-2019:
①. Izakhiwo zomphakathi ezinokuphakama kwe-100m noma ngaphezulu;
②. Izakhiwo zomphakathi ezinokuphakama phakathi kuka-50m no-100m nendawo edlula nge-100,000㎡;
③. Izikhungo zedatha zebanga le-B noma ngaphezulu;
Lokhu kufanele kusebenzise amakhekhe we-Flame-Retardant
Ku-UL1651 Standard e-US, Uhlobo lwe-Cable Cable oluphakeme kakhulu lwe-Flame-Retardant luyikhebula le-Optical Ngokwengeziwe, ayikhiphi intuthu enobuthi noma umphunga, okwenza kufanelekile ukufakwa ku-duct yokufaka umoya omncane noma izinhlelo zokubuyela emuva komoya ezisetshenziselwa imishini ye-HVAC.
