ADSS optical fiber tambo inoshanda munzvimbo yepamusoro inotsigirwa nemapoinzi maviri ane kureba kwakakura (kazhinji mazana emamita, kana kutopfuura 1 km), iyo yakasiyana zvachose neyechinyakare pfungwa ye "pamusoro" (posvo uye nharembozha yakarembera pamusoro. wire hook program, avhareji yemamita 0.4 haina mhedzisiro pane optical cables).1 pivot).Naizvozvo, iyo mikuru paramita yeADSS optical cables inoenderana nemirairo yesimba pamusoro pemitsara.
1. Tension (MAT / MOTS) inobvumirwa.
Inoreva kushushikana kwetambo ye optical apo mutoro wose unofungidzirwa kuverengwa pasi pekugadzirwa kwemamiriro emamiriro ekunze.Pasi pekutambudzika uku, iyo fiber strain inofanira kuva ≤0.05% (layer twist) uye ≤0.1% (center tube) pasina kuwedzera attenuation.Mukutaura kwe layman, ndiko kuti, kureba kweiyo optical fiber inongo "kudyiwa" pane iyi kukosha kwekutonga.Zvinoenderana neiyi parameter uye meteorological mamiriro uye inodzorwa sag, inotenderwa kushandiswa kwetambo ye optical tambo pasi peichi mamiriro inogona kuverengerwa.Naizvozvo, MAT ndiyo hwaro hwakakosha hwekuverengera kwesag-tension-span, uye zvakare humbowo hwakakosha hunoratidza kushushikana-strain maitiro eADSS optical cables.
2. Rated tensile simba (UTS/RTS).
Iyo inozivikanwawo seyekupedzisira tensile simba kana simba rekupwanya, inoreva kukosha kwakaverengerwa kwehuwandu hwekusimba kweiyo inotakura muchinjiko-chikamu (kunyanya machira machira).Simba rekupwanya chairo rinofanirwa kunge riri ≥95% yemutengo wakaverengerwa (kutyoka kwechinhu chero chipi zvacho mutambo yemaziso kunotongwa sekuputsika kwetambo).Iyi parameter haisi yekusarudzika, uye akawanda ehutongi ane hukama nayo (senge simba reshongwe, tensile fittings, anti-vibration matanho, nezvimwewo).Kune optical cable professionals, kana chiyero cheRTS / MAT (yakaenzana nekuchengetedza chinhu K chemitsetse yepamusoro) haina kukodzera, kunyange kana yakawanda fiber inoshandiswa, uye inowanikwa optical fiber strain range yakanyanya kutetepa, iyo yehupfumi / technical performance ratio yakashata kwazvo.Naizvozvo, munyori anokurudzira kuti vanhu vari muindasitiri vateerere kune iyi parameter.Kazhinji, MAT inenge yakaenzana ne40% RTS.
3. Gore negore zvinoreva kushungurudzika (EDS).
Dzimwe nguva dzinonzi avhareji yekushushikana kwezuva nezuva, zvinoreva kushushikana kwetambo pasi pemutoro weiyo theoretical kuverenga pasi pemamiriro ekushaya mhepo, hapana ice uye epakati tembiricha tembiricha, iyo inogona kutorwa seavhareji kushushikana (kunetsa) kwemhepo. ADSS panguva yekushanda kwenguva refu.EDS kazhinji (16 ~ 25)% RTS.Pasi pekukakavadzana uku, iyo fiber inofanira kunge isina strain, pasina kuwedzera attenuation, kureva kuti yakagadzikana.EDS zvakare ndiyo yekuneta kuchembera paramende yetambo yemaziso, uye iyo anti-vibration dhizaini yetambo yemaziso inotemerwa zvinoenderana neiyi parameter.
4. Ultimate Running Tension (UES).
Iyo inozivikanwawo seyakakosha kushandiswa tension, inoreva kune tension iyo tambo inoiswa pasi kana mutoro unopfuura dhizaini mutoro panguva yehupenyu hunoshanda hwetambo yemaziso.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 fiber strain iri pasi pe 0.5% (center tube) uye <0.35% (layer twist), fiber ichava nekuwedzera attenuation, asi mushure mokunge mhirizhonga yasunungurwa, fiber inofanira kudzokera kune yakajairika.Iyi parameter inovimbisa kushanda kwakachengeteka kweiyo ADSS tambo panguva yehupenyu hwayo.
