OPGW Optical cableinonziwo optical fiber composite pamusoro pevhu waya.OPGW optical cable OPGW optical cable inoisa optical fiber muwaya yevhu yepamusoro-high-voltage transmission line kuti iumbe optical fiber communication network patambo yekutumira.Ichi chimiro chine mabasa maviri epasi waya uye kutaurirana, uye inowanzonzi OPGW optical tambo.Iyo yekumisikidza dhizaini yeOPGW inofanirwa kutarisisa kurongeka newaya kushushikana, sag uye gap rekudzivirira, uye mutoro wayo haufanirwe kudarika inobvumidzwa huwandu hweshongwe dziripo uye nheyo.Naizvozvo, iyo hunhu curve inofanirwa kuverengerwa zvichienderana neiyo huru yehunyanzvi paramita yeOPGW yakasarudzwa, uye marongerwo, ratidziro uye yekumisikidza dhizaini yebhokisi rekusangana, akasiyana hardware uye zvishongedzo zvinofanirwa kugadzirwa zvakabatana neinjiniya chaiyo.Kuwedzera kuverenga: Ko OPGW vagadziri vetambo vanovimbisa sei kunaka kwetambo dzemaziso
OPGW optical tambo yekuisa chimiro dhizaini kufunga
1. Kurapa kwekutanga elongation
Kurapa kwekurebesa kwekutanga kweOPGW, nzira yekutonhora inogona kushandiswa, kureva, aluminium-steel ratio yeOPGW inodzokororwa, uye elongation yekutanga inobatwa nekutarisa kukosha kwekutonhora kwetambo yakafanana kana pasi. waya.
2. Dhizaini yematanho ekurwisa kudengenyeka
Pakati pezvigadziriso zvinoshandiswa neOPGW, iyo tension clamp ndeye pre-yakamonyoroka mhando yewaya, uye yekumisikidza waya yekusungirira ine pre-yakamonyoroka waya uye rubber gasket.Aya marudzi maviri ekuisa ane mamwe anti-vibration kugona.Kuti uwedzere kusimbisa iyo anti-vibration kugona, zvinokwanisika kufunga kuisa anti-vibration sando, iyo inowanzoverengerwa zvichienderana nespan:
Kana span iri pasi kana yakaenzana ne300M, isa anti-vibration sando;
Kana span yasvika> 300M, isa sando mbiri dze-anti-vibration.
3. Matambudziko anofanirwa kutariswa pakuvaka nekumisa OPGW
Kuvaka uye kumiswa kweOPGW kwakasiyana neakajairwa tambo dzesimbi.Kuchengetedza kunofanira kutorwa kudzivirira kukanganisa zvachose kudzivirira kukanganisa kushanda kwefiber optical mune ramangwana, uye inofanira kutarisa pane: OPGW torsion, micro-bending, local radial pressure kunze kwe clip uye kusvibiswa kune optical fiber.Naizvozvo, padanho rekuvaka, anotevera matanho anoshanda anofanirwa kutorwa kuigadzirisa:
(1) Dzivirira OPGW kubva pakumonyoroka
Isa counterweight uye anti-twist mudziyo pabhodhi uye inosimbisa simbi;
Gamuchira yakakosha kaviri-groove pulley;
Tension line muchina une kaviri winch;
(2) Dzivirira uye kuderedza microbending uye kusagadzikana kweOPGW
Hapana acute angles anotenderwa (minimum beng radius is 500mm);dhayamita yeOPGW tambo reel haifanire kunge iri pasi pe1500mm;
Iyo dhayamita yepulley inofanira kunge inopfuura makumi maviri neshanu dhayamita yeOPGW, kazhinji isiri pasi pe500mm;chikamu chemukati chepulley chinofanira kuva nenylon kana rubber lining kudzivirira kukwenya pamusoro peOPGW;
Yakakodzera kudhonza waya uye kubhadhara-off fittings;
Rondedzera kureba kwekoiri yeOPGW kuve 6000M kudzivirira huwandu hwenguva iyo pulley inopfuura;
Mutsara wekutenderera angle yekuenderera mberi kwekubhadhara inogumira ku ≤30 °.Muchikamu chekunetseka chekubhadhara, hutungamiri hweOPGW mushure mekona inofanira kunge iri muchimiro che "C";
(3) Kudzora kwekunetsekana kwekubhadhara:
Adopt hydraulic tension pay-off uye tirakita ine tension kuburitsa mudziyo;
Kuderedza kukurumidza kubhadhara ≤ 0.5 m / s;
(4) Dzivirira kusvibiswa kwefiber
Mukuvaka uye kumiswa kweOPGW, kutarisisa kunofanirwa kubhadharwa kune encapsulating migumo;
Pakupedzisira, tinofanira kuyeuchidza munhu wose kuti OPGW isati yasvika panzvimbo, isati yagadzirwa, mushure mekupedzwa kwekugadzirisa uye optical fiber connection uye kupera kwekugadzirwa kwemutsara wose, OPGW fiber attenuation kugamuchira bvunzo inofanira kuitwa. panzvimbo nenguva.
