Ikhebula Le-OPGW Elingaphezulu Kulayini Wokudlulisa I-Aluminium Clad Steel Tube
LANDA IZINCAZELO ZESIKHATHI
Isicelo
Ikhebuli ye-OPGW ephezulu ifanele ukufakwa ezintanjeni zokudlulisela futhi inomsebenzi ombaxambili wezintambo eziphansi (eziklanyelwe ukufaka esikhundleni sezintambo ezivamile ezimile noma ezivikelayo) kanye nezintambo zokuxhumana.
I-OPGW iqhuba imisinga yesiyingi esifushane futhi inikeza isivikelo ekushayweni kombani ngenkathi "ivikela" amakhondaktha, kuyilapho inikeza indlela yokuxhumana ngocingo yokuxhumana kwangaphakathi nenkampani yangaphandle.
I-OPGW kumele ikwazi ukumelana nezingcindezi zemishini nezemvelo ezibekwa phezu kwezintambo (njengalezo ezibangelwa umoya noma iqhwa).I-OPGW kufanele futhi ikwazi ukuphatha amaphutha kagesi entanjeni yokudlulisela ngokunikeza indlela eya phansi kuyilapho ivimbela ukulimala kumafiber optical athambile ngaphakathi kwekhebula.
Ukwakha
Ikhebula le-OPGW linezakhiwo ezimbili:
1. Uhlobo lweshubhu evulekile emaphakathi
Amafayibha afakwa ngokukhululekile epayipini elivalekile nelikwazi ukumelana namanzi, ishubhu le-aluminium eligcwele ijeli elivimba amanzi.Le tube ihlinzeka ngokuvikeleka ku-fiber ngesikhathi sokufakwa nokusebenza ngaphansi kwezimo ezinzima zemvelo.Ishubhu yensimbi engagqwali ingase futhi ibe insimbi egqoke i-aluminium kuye ngezidingo zobunjiniyela.Ishubhu ye-stainless Optical itholakala phakathi nendawo yekhebuli evikelwe izendlalelo ezizodwa noma eziningi ze-aluminium clad steel, izintambo ze-aluminium alloy, noma izintambo zensimbi.Izintambo zensimbi zinikeza amandla emishini ukuze zimelane nezimo ezinzima zokufakwa nezimo zokusebenza, kuyilapho zithola i-conductivity yokulawula ukukhuphuka kwezinga lokushisa phakathi nezimo zesekethe elifushane.
I-optical fiber ngayinye ihlukaniseka ngokucacile kusetshenziswa isistimu yokuhlonza ifayibha ehlanganisa umbala kanye nenani lamamaki amaringi kuwo.Lo mklamo ohlangene uhlanganisa amandla emishini aphezulu kanye nesilinganiso samanje esinephutha ngaphakathi kobubanzi obuncane.Ububanzi obuncane buphinde buphumele ekusebenzeni okuhle kakhulu kwe-sag tension.
2.Multi okuxekethile uhlobo tube
Imicu ifakwa ngokukhululekile eshubhu lensimbi engenasici elivalekile nelikwazi ukumelana namanzi eligcwele ijeli elivimba amanzi.Amashubhu okusebenza ensimbi engagqwali amabili noma amathathu aboshwe ngomumo ongqimbeni lwangaphakathi lwekhebula elinezingqimba eziningi.I-multi loose tube type yakhelwe ikakhulukazi imfuneko ye-fiber count ephezulu kakhulu engaphezu kuka-48 kanye nenani eliphezulu le-fiber count lifinyelela ku-144. I-multi loose tube type ingahlangabezana nemfuneko yesiphambano esikhulu namandla amanje amakhulu.
I-fiber optical yenziwe nge-silica ehlanzekile ephezulu kanye ne-germanium doped silica.Izinto ze-acrylate ezelaphekayo ze-UV zisetshenziswa phezu kwe-fiber cladding njenge-optical fibre primary protective coating.Idatha yemininingwane yokusebenza kwefiber optical ikhonjiswe kuthebula elilandelayo.
I-Optical fibre isebenzisa idivayisi ekhethekile yokuphotha ilawule ngempumelelo inani le-PMD, futhi iqinisekisa ukuthi ingakwazi ukugcina izinzile kukhebula.

Amanothi
Ubude be-reel kufanele buchazwe ngesikhathi sokuthenga ukusiza iklayenti ngokunciphisa imfucuza, nokunciphisa ukuhlanganisa okudingekayo ngesikhathi sokufakwa.
Sicela uxhumane ne-AWG ukuze uthole imininingwane egcwele yobuchwepheshe, okuhlanganisa idatha ye-PLS CADD noma idatha ye-Stress Creep.
