Ikhebula le-OPGW, eyaziwa nangokuthi ucingo lomhlabathi oluhlanganisiwe lwe-optical fiber. I-optical fiber ifakwa ocingweni lomhlabathi womugqa wokudlulisela we-high-voltage ongaphezulu bese ifakwa phezulu kombhoshongo womugqa wokudlulisela ukuze kwakhiwe inethiwekhi yokuxhumana ye-optical fiber emgqeni wokudlulisela. Lolu hlobo lwesakhiwo lunemisebenzi emibili yocingo lomhlabathi kanye nokuxhumana, futhi ngokuvamile lubizwa ngokuthi ikhebula le-OPGW optical.

Ikhebula le-OPGW ligoqwa ngocingo lwensimbi, ukuze ikhebula lithembeke kakhudlwana, lizinze futhi liqine, ngoba ucingo oluphezulu kanye nekhebula kuhlanganiswe ndawonye, ​​uma kuqhathaniswa nokusetshenziswa kwezinye izindlela zekhebula, kokubili kunciphisa isikhathi sokwakha futhi konge izindleko zokwakha. Ngaphezu kwalokho, uma kusetshenziswa i-OPGW eyenziwe ngocingo lwensimbi olumbozwe nge-aluminium noma ucingo lwe-aluminium alloy, kufana nokusetha ucingo oluhle oluphezulu, olungathola izinzuzo eziningi njengokunciphisa ugesi ofihliwe womugqa wokudlulisa, ukunciphisa i-overvoltage yemvamisa yamandla, kanye nokuthuthukisa ukuphazamiseka kanye nomthelela oyingozi womugqa wamandla emgqeni wokuxhumana.

I-OPGW ifanele imigqa enamandla kagesi adlula i-110kv, futhi isikhala sikhulu (ngokuvamile singaphezu kwama-250M); Kulula ukuyinakekela, kulula ukuyixazulula inkinga yokuwela umugqa, izici zayo zemishini zingahlangabezana nokuwela umugqa; Ingqimba yangaphandle ye-OPGW ihlotshiswe ngensimbi, engenawo umthelela ekugqwaleni nasekuwohlokeni kwamandla kagesi aphezulu. I-OPGW kumele inqunywe ngesikhathi sokwakhiwa, futhi ukulahlekelwa ugesi kukhulu, ngakho-ke i-OPGW kufanele isetshenziswe emigqeni emisha enamandla kagesi adlula i-110kv; I-fiber yenziwe nge-fiber yengilazi, ebuthakathaka futhi ebuthakathaka.

Ngesikhathi senqubo yokwakha, i-OPGW kufanele ivinjelwe ukuthi ingadonswa, ihlukunyezwe, iklwebheke, ichotshozwe, iphuke, futhi ikhebula kufanele lidonswe kahle ngaphandle kokucindezelwa.

Amaphuzu Okulawula Ikhwalithi Yokufakwa kwe-OPGW

1. Ukumiswa kwekhebula le-OPGW kufana nomugqa kagesi, lapho kumiswa, umugqa wokuqala wokudlulisa kumele ube ukusebenza kokungasebenzi, okuvinjelwe emoyeni, ekuvunguzeni, emakhazeni nasekushiseni kanye nakwezinye izakhiwo zesimo sezulu esibi. Irediyasi yokugoba yekhebula kufanele ibe ngaphezu kuka-0.5m.

2. Ukwakhiwa kufanele kugweme ikhebula elihlangene, ukuze kugwenywe umonakalo wengqimba yangaphandle yekhebula. Ukugoba okunamandla akufanele kube ngaphansi kobubanzi bekhebula obuphindwe ka-40, okungukuthi, ekwakhiweni ukuqinisekisa ukuthi okungenani kunerediyasi yokugoba engu-600mm, ikhebula le-OPGW alikwazi ukusonteka.

Kuyobekwa abasebenzi abakhethekile ukuqapha ukuwela kwemizila emikhulu yezimoto, izintambo zokuxhumana, izintambo zikagesi, njll. Intambo kumele ilawulwe endaweni ephakeme ephephile ukuze kugwenywe ukushayisana noma ukugingqika kwentambo yizimoto, okuzobeka engcupheni ukuphepha kwentambo noma abasebenzi.

3. Izidingo zokumiswa kwekhebula le-OPGW endaweni yokuwela phansi: indawo engenamuntu, i-OPGW ishiye umhlabathi ngaphezu kwamamitha amathathu; Imigwaqo yabahamba ngezinyawo kanye nemigwaqo enezimoto ezimbalwa, i-OPGW ingaphezu kwamamitha amahlanu ukusuka phansi; Imigwaqo emikhulu kanye nezitimela, i-OPGW ngaphezu komhlabathi ingamamitha angu-7.5.

4. Enqubweni yokwakha, naka ukuvikelwa kwengqimba yangaphandle yentambo eboshiwe. Intambo yensimbi eboshwe nge-aluminium yangaphandle noma intambo ye-aluminium alloy iyisithwali sokushaya kombane ngokweqile kanye nombani, njengokulimala kuzoba nezingozi zesikhathi eside emgqeni. Hlola i-pulley ukuze ubone ama-burrs; Ungalahli noma ulahle izintambo ze-optical; Sebenzisa i-casing yerabha ukuze uvikele uma usebenzisa i-wire lifter. Ithreyi yekhebula ye-OPGW ibekwa ku-rack yokukhokha noma emotweni yethreyi yekhebula enomgodi ojikelezayo, futhi ibanga phakathi kwethreyi yekhebula kanye nesikhungo somshini wokucindezela kufanele liqinisekiswe ukuthi lingama-5-8m.

5. Nsuku zonke kufanele kuqinisekiswe ukuthi ukwakhiwa kwediski eyodwa yekhebula le-optical kuqediwe, uma kungengobusuku obubodwa noma isikhathi eside, kumele kusetshenziswe intambo ye-nylon ukulungisa ikhebula le-OPGW ku-pulley, ukuvimbela ukushelela kwekhebula le-optical kanye nomonakalo wokukhathala endaweni yokuxhumana ye-optical fiber ne-pulley. Ngesikhathi esifanayo, intambo yokudonsa kanye nekhebula le-optical kufanele kuboshwe okwesikhashana ekugcineni kokudonsa kanye nasekupheleni kokucindezela ngokulandelana. Izinga lokuphumula lekhebula phakathi kwephuzu lomugqa we-anchor ekupheleni kokucindezela kanye nomshini wokucindezela lifanelekile ukuze kuncishiswe ukucindezeleka komshini wokucindezela. Akukwazi ukuba buthakathaka kakhulu, ikhebula akumele lisule phansi.
