OPERATION MANOR
Zvinokurudzirwa kuti kuvakwa uye wiring yeiyi ASU optical tambo itore nzira yekurembera erection. Iyi nzira yekumisikidza inogona kuwana yakanakisa kunzwisisika maererano neiyo erection kunyatsoita, erection mutengo, kuchengetedzwa kwekushanda uye kuchengetedza kwemhando yetambo ye optical. Nzira yekushanda: Kuti usakuvadza sheath yetambo yemaziso, iyo pulley traction nzira inowanzogamuchirwa. Sezvinoratidzwa mumufananidzo, isa tambo yekutungamira uye maviri egwaro pulley kune rimwe divi (kutanga kupera) uye divi rekudhonza (terminal end) yeiyo optical cable reel, uye isa hombe pulley (kana yakasimba inotungamira pulley) panzvimbo yakakodzera. yedanda. Batanidza tambo yekukwevera uye tambo yemaziso neinotsvedza, wobva waisa dhizaini yega yega 20-30m pamutsetse wekumisa (mugadziri ari nani kukwira papulley), uye pese painogadzikwa pulley, tambo yekukwevera inoiswa. yakapfuura nemupulley, uye mugumo unodhonzwa nemaoko kana netarakita (teerera kune tension control). ) Kudhonza kwetambo kwapera. Kubva kune rumwe rutivi, shandisa optical cable hook kusungirira tambo yemaziso pamutsara wekumisa, uye kutsiva iyo inotungamira pulley. Nhambwe iri pakati pezvikorekedzo nemachira i50±3cm. Mufambo uri pakati pehoko dzekutanga kumativi ese edanda ungangoita 25cm kubva panogadzikwa waya yekurembera padanda.
Muna 2019, GL yakapinda muBrazil Optoelectronics Expo, uye kutengesa kwayo bhizinesi refekitori kwakasvika mazana matatu emamiriyoni, iyo yakakosha chigadzirwa OPGW optical tambo yakaverengerwa mamirioni zana nemakumi masere, zvigadzirwa zvedehwe waya zvakasvika mamirioni makumi mashanu, uye tambo dzeasu optical uye zvishongedzo zvakaenzana. 100 mamiriyoni.
Muna 2022, yedu ASU-80 optical tambo yakapfuura iyo ANATEL certification muBrazil, OCD (ANATEL subsidiary) chitupa nhamba:Nº 15901-22-15155; Chitupa chebvunzo webhusaiti:https://sistemas.anatel.gov.br/mosaico /sch/publicView/listarProdutosHomologados.xhtml.
