Hunhu hwetambo yeADSS neGwara reMutengo

2025-03-2020

Uri kubvunza nezve Tambo dzeADSS tichitarisa pamhando yepamusoro nemutengo. Regai nditsanangure izvi. Kutanga, kuti tambo dzeADSS chii. Idzo tambo dzese dzinotsigira muviri dzinoshandiswa mukuisa fiber optic pamusoro pemusoro. Pfungwa huru pano imhando yepamusoro nemutengo.

 

Saka, mushandisi angangoda kuziva kuti chii chinoita kuti tambo yeADSS yemhando yepamusoro uye kuti mitengo inoshanda sei. Ndinofanira kutanga nekutsanangura zvinhu zvinosarudza mhando. Izvi zvinosanganisira zvinhu zvinoshandiswa, senge rudzi rwegirazi riri mushinda, jira rejaketi (HDPE inowanikwa), uye shinda yearamid yekusimba. Zvakare, zvinhu zvakaita sekusimba kwekusimba uye kuramba kwemamiriro ekunze zvakakosha.

 

Tevere, zvinhu zvine chekuita nemitengo. Ndinoda kutaura kuti mutengo unoenderana nehuwandu hwefiber, kureba, chiyero chekudhonza, uye chero zvimwe zvinhu zvakaita sekudzivirira mbeva. Vatengesi vanogona kupa zvidzikiso zvehuwandu, saka pamwe vangakurudzira kuti uvabate zvakananga kuti uwane mitengo. Zvakare, mukurumbira wemhando yacho une basa pano - mhando dzine mukurumbira dzinogona kudhura zvakanyanya asi dzinopa kuvimbika.

 

Zvadaro, vatengesi vanokurudzirwa. Mazita akaita seCorning, Prysmian, Fujikura, AFL, naFeiboer anouya mupfungwa. Aya makambani anozivikanwa nerunako. Kusanganisira vatengesi vekunze nevekuChina kunogona kubatsira sezvo mushandisi angave achitsvaga sarudzo munzvimbo dzakasiyana.

 

Ndinofanirawo kuwedzera mazano ekuona kukosha kwemari. Zvinhu zvakaita sekusimbisa zvitupa (ISO, RoHS), kutarisa hunyanzvi hwebasa maererano nezvinodiwa neprojekiti, kuwana sampuro, uye kuenzanisa mitengo. Pamwe taura kukosha kwerutsigiro rwemushure mekutengesa uye garandi.

 

Mira, mushandisi anogona kunge ari muvaki kana maneja wepurojekiti ari kutsvaga kutenga tambo idzi. Vanoda kuenzanisa mutengo pasina kukanganisa mhando. Saka kusimbisa kuenzana pakati pemhando nemutengo kwakakosha. Pamwe simbisa kuti kunyangwe mitengo yekutanga ingave yakakwira yezvigadzirwa zvemhando yepamusoro, vanochengetedza mari nekufamba kwenguva kuburikidza nekugara kwenguva refu uye kusagadzirisa zvakanyanya.

 

Ndinofanirawo kufunga nezvemitengo isingaonekwe. Semuenzaniso, tambo yakachipa inogona kunge isina simba rakawanda rekudhonza, zvichiita kuti iwedzere kuchinjika kana kutadza kushanda, izvo zvinowedzera mutengo wese. Saka zvakakosha kurayira kuti usashandise zvinhu zvakakosha zvakanyanya.

 

Uyewo, nzvimbo yekushandisa inokosha. Kana kuiswa kwacho kuri munzvimbo ine mamiriro ekunze akaoma, mhepo ine simba, kana tembiricha yakanyanya, tambo yacho inofanira kumira mumamiriro ezvinhu akadaro. Saka zvinhu zvemhando yepamusoro zvinofanirwa kuenderana nezvinodiwa nenharaunda.

 

Pamwe sanganisira mitengo yakatarwa, asi sezvo mitengo ichichinja-chinja uye zvichienderana nezvaunoda, zviri nani kukukurudzira kuti uwane mutengo wakagadzirirwa iwe. Zvisinei, kupa nhamba yepakati pe $0.50 kusvika $2 pamita imwe neimwe kunogona kubatsira pakuisa tarisiro, asi ndinofanira kungwarira sezvo izvi zvinogona kusiyana zvakanyanya.

 

Kusanganisira vatengesi vekunze nevekuChina zvakanaka nekuti vagadziri vekuChina vakaita seFeiboer, Hengtong kana ZTT vanogona kupa mitengo inokwikwidzana, izvo zvinogona kukwezva kana mushandisi achinyatsofunga nezvebhajeti asi achiri kuda mhando yakavimbika.

 

Uyewo, kutaura nezvekukosha kwemukurumbira wemutengesi uye sevhisi yekutengeswa mushure mekutengesa kunogona kutungamira mushandisi kuti afunge kwete nezvechigadzirwa chete asiwo rutsigiro rwuripo. Rutsigiro rwehunyanzvi panguva yekuisa runogona kuva rwakakosha kune munhu asina ruzivo rwekare netambo dzeADSS.

 

Ndinofanira kuronga mhinduro yacho nekutanga ndatsanangura zvinosarudza mhando, ndozotevera mitengo, ndozotevera mazano evatengesi, uye mazano ekuwana mutengo wakanakisisa. Kupedzisa nemhedziso inosimbisa chiyero pakati pemhando uye kushanda zvakanaka kwemutengo.

 

Unofanira kuva nechokwadi chekuti mazwi ese ehunyanzvi anotsanangurwa zvakajeka, asi pasina kutaura zvakawanda. Mushandisi anogona kunge atoziva zvekutanga, asi zviri nani kunyatsotsanangura. Dzivisa mutauro wakaoma kana zvichibvira, kana kuti tsanangura muchidimbu.

 

Tarisa kana paine mitemo yeindasitiri ine chekuita netambo dzeADSS inofanira kutaurwa, senge mitemo yeIEC kana Telcordia. Kutevedzera mitemo iyi kunogona kuratidza kuti zvinhu zvakanaka here.

 

Zvakare, pamwe taura nezvesarudzo dzekugadzirisa. Vamwe vatengesi vanopa tambo dzakagadzirirwa zvinodiwa, izvo zvinogona kukanganisa mutengo uye kukodzera kwepurojekiti.

 

Chekupedzisira, iva nechokwadi chekuti zano racho rinoshanda. Mushandisi angangoda matanho anogona kushandiswa: maitiro ekuongorora vatengesi, zvinhu zvekutarisa, maitiro ekutaurirana mitengo, nezvimwewo.

Kana uchifunga nezveTambo dzeADSS (All-Dielectric Self-Supporting), kuenzanisamhandouyemutengozvinoda kunzwisisa zvinhu zvikuru zvinopesvedzera zvese zviri zviviri. Heino gwara rakarongeka rekukubatsira kuita sarudzo ine ruzivo:

Zvinhu Zvinokosha Zvehunhu

  1. Hunhu hwezvinhu:

    • Mafiber eOptical: Corning, OFS, kana Yangtze Optical fibers dzinoita kuti bandwidth iwedzere uye kuti bandwidth iwedzere.

    • bhachi: Polyethylene ine huwandu hwakanyanya (HDPE) ine simba rekudzivirira UV/mamiriro ekunze.

    • Nhengo dzeSimba: shinda yeAramid (semuenzaniso, Kevlar) yekusimba kwekusimba.

  2. Magadzirirwo ehunyanzvi:

    • Simba reKusimba: Yakaenzana nehurefu hwespan uye mitoro yezvakatipoteredza (semuenzaniso, mhepo/chando).

    • Nzvimbo yekupisa: -40°C kusvika +70°C kana mamiriro ekunze akaoma.

    • Kuwanda kweFiber: 12 kusvika 144 cores, zvichienderana nezvinodiwa neprojekiti.

  3. Zvitupa:

    • TsvagaIEC,Telcordia GR-20, kanaANSIkutevedzera mitemo.

    • Zvitupa zveRoHS/ISO zvemitemo yekuchengetedzwa kwezvakatipoteredza.

Zvinosarudza Mutengo

  1. Kuwanda kweFiber: Kuwanda kwenhamba dzepakati kunowedzera mutengo (semuenzaniso, 144-core vs. 24-core).

  2. Kuyera Kusimba: Tambo dzakatarwa kuti dzishande ne20kN+ dzinodhura kupfuura 10kN yakajairwa.

  3. Kugadzirisa: Majaketi ane nhumbi dzehondo kana magadzirirwo anodzivirira makonzo anowedzera 10–20% pamutengo wekutanga.

  4. Vhoriyamu yeodha: Kutenga zvinhu zvakawanda (semuenzaniso, makiromita anopfuura gumi) kunowanzoita kuti pave nekudzikiswa kwemitengo.

  5. Nzvimbo yeMutengesiVagadziri vekuChina (semuenzaniso, Feiboer, Hengtong, ZTT) vanowanzopa mitengo yakaderera pane mabrandi ekuMadokero (semuenzaniso, Corning, Prysmian).

Mitengo Inofungidzirwa

Kuwanda kweFiber Mutengo (USD/mita) Zvinyorwa
12–24 macore 0.50–1.50 Bhachi reHDPE rekutanga, 10kN rinonamira
48–96 macore 1.00–2.50 Kudhonza kwepakati (15–20kN)
144 macores 2.00–4.00 Dhizaini dzakasimba (20–30kN), dzakagadzirwa nemaoko

Cherechedza: Mitengo inosiyana zvichienderana nemutengesi, dunhu, uye mamiriro emusika (semuenzaniso, kushomeka kwefiber mushure medenda).

Vatengesi Vanokurudzirwa

  1. Mhando dzepamusoro:

    • Corning(US)

    • Prysmian(Itari)

    • Fujikura(Japani)
      Zvakanakisa pakuvaka zvivakwa zvakakosha, asi mutengo wakakwira.

  2. Sarudzo Dzinodhura Mari Yakawanda:

    • Murimi(China)

    • ZTT(China)

    • AFL(US/Asia)
      Mitengo inokwikwidzana pasina kukanganiswa kukuru kwemhando.

  3. Vagoveri:

    • Fiberstore (FS.com)– Maodha akagadzirwa, zvidzikiso zvakawanda.

Mazano eKukosha

  1. Kumbira Mienzaniso: Edza kuderedza simba uye kushanda zvakanaka kwekukwesha.

  2. Enzanisa MashokoShandisa mapuratifomu akaita seAlibaba kana zvakananga RFPs pakutenga mavhoriyamu.

  3. Garandi: Chinangwa chemakore 15-25 ekushandisa tambo dzemudenga.

  4. Rutsigiro rweKutengesa Mushure meKutengesa: Iva nechokwadi chekuti mutengesi anopa gwara rekuisa.

Mhedziso

Zvemhando yakanaka pamitengo inokwikwidzana, funga nezvevatengesi vepakati vakaita seFeiboer, Hengtong kana Fiberstore. Isa zvitupa uye kuyera tensile ratings pamberi pekukudzwa kwechiratidzo chechiratidzo cheprojekiti dzisina kukosha. Gara uchisimbisa zvirevo zvichienderana nezvaunoda (semuenzaniso, nzvimbo dzechando/mhepo). Kuti uvimbike kwenguva refu, dyara mari muzvigadzirwa zvine mukurumbira wekuisa zvinhu zvine njodzi.

Ndiudzei kana muchida rubatsiro pakunyora RFP kana kuongorora zvirevo! 🌐

Taura Nesu, Wana Zvigadzirwa Zvemhando Yepamusoro uye Basa Rekungwarira.
