TheADSS optical fiber tamboinoshanda munzvimbo yepamusoro inotsigirwa nemapoinzi maviri ane span yakakura (kazhinji mazana emamita, kana kutopfuura kiromita imwe), iyo yakasiyana zvachose neyechinyakare pfungwa ye "pamusoro" (iyo post uye telecommunication standard overhead suspension wire hook chirongwa. , avhareji yemamita 0.4 ine pivot 1).Naizvozvo, iyo mikuru paramita yeADSS optical fiber tambo inoenderana nemirairo yemagetsi epamusoro mitsetse.
1. Tension inobvumirwa (MAT/MOTS)
Inoreva kushushikana patambo ye optical apo mutoro wakazara unoverengerwa pasi pemamiriro ekunze ekugadzira.Pasi pekutambudzika uku, iyo fiber strain inofanira kuva ≤0.05% (layer twist) uye ≤0.1% (central tube) pasina kuwedzera attenuation.Mukutaura kwe layman, kureba kweiyo optical fiber inongo "kudyiwa" pane iyi kukosha kwekutonga.Zvinoenderana neiyi parameter, mamiriro emamiriro ekunze uye inodzorwa sag, iyo inobvumidzwa span ye optical cable pasi peichi mamiriro inogona kuverengerwa.Naizvozvo, MAT ndiyo hwaro hwakakosha hwekuverengera kwesag-tension-span, uye zvakare humbowo hwakakosha hwekuratidza kushushikana-kunetseka maitiro eADSS tambo.
2. Yakatemerwa tensile simba (UTS/RTS)
Iyo inozivikanwawo seyekupedzisira kusimba simba kana simba rekupwanya, inoreva kukosha kwakaverengerwa kwehuwandu hwesimba rechikamu chinotakura (kunyanya kuverenga kuruka fibers).Iyo chaiyo yekupwanya simba inofanirwa kunge iri ≥ 95% yemutengo wakaverengerwa (kutsemuka kwechero chikamu mutambo inotongwa sekuputsika kwetambo).Iyi parameter haigone kubviswa, uye akawanda ehusheji hutongi ane hukama nayo (senge shongwe simba, tensile fittings, shockproof matanho, nezvimwewo).Kune iyo optical cable industry, kana chiyero cheRTS / MAT (yakaenzana nekuchengetedzwa kwechikonzero K chemutsetse wepamusoro) haina kukodzera, kunyange kana yakawanda fiber inoshandiswa, uye inowanikwa optical fiber strain range yakanyanya kuduku, iyo Economic/technical performance ratio yakashata kwazvo.Naizvozvo, munyori anokurudzira kuti vanhu vari muindasitiri vateerere kune iyi parameter.Kazhinji, MAT inenge yakaenzana ne40% RTS.
3. Annual Mean Stress (EDS)
Dzimwe nguva dzinonzi avhareji yekushushikana kwezuva nezuva, inoreva kushushikana kwetambo kana mutoro uchiverengerwa pasi pasina mhepo, pasina ice uye tembiricha yegore negore, iyo inogona kutorwa seavhareji tensile (kushushikana) simba reADSS munguva refu. kushanda.EDS kazhinji (16 ~ 25)% RTS.Pasi pekukakavadzana uku, iyo fiber haifanirwe kunge isina kuomarara uye isina kuwedzera attenuation, ndiko kuti, yakagadzikana.EDS zvakare ndiyo yekuneta kuchembera paramende yetambo yemaziso, uye iyo anti-vibration dhizaini yetambo yemaziso inotemerwa zvichibva pane iyi parameter.
4. Ultimate operating tension (UES).
Iyo inozivikanwawo seyakakosha kushandiswa tension, inoreva kushushikana pane tambo kana zvichikwanisika kupfuudza dhizaini mutoro panguva yehupenyu hunoshanda hwetambo.Zvinoreva kuti tambo ye optical inobvumirwa kuremerwa kwenguva pfupi, uye optical fiber inogona kumira kuomarara mukati mechikamu chinotenderwa.Kazhinji, iyo UES inofanirwa kunge iri> 60% RTS.Pasi pekutambudzika uku, iyo optical fiber strain ndeye <0.5% (central tube) uye <0.35% (layer twisted), uye optical fiber ichava nekuwedzera attenuation, asi mushure mokunge mhirizhonga yasunungurwa, optical fiber inofanira kudzokera kune yakajairika.Iyi parameter inovimbisa kushanda kwakavimbika kweiyo ADSS tambo panguva yehupenyu hwayo.
