GL Technology Latest OPGW Installation Manual
Zvino, Ngatienderere mberi nefundo yeduOPGW Hardware uye ZvishandisoInstallation nhasi.
Isa zvigadziriso uye zvishongedzo mumaawa makumi mana nemasere mushure mekusimbisa tambo muchikamu chetension kudzivirira kukuvadzwa kusingakoshi kune fiber kunokonzerwa nekuneta kwetambo, nekuti tambo inogona kubvongodzwa nyore nyore kana kuzunguzika mupulley.Zvishongedzo uye zvishongedzo zveOPGW zvinowanzo sanganisira: tension clamp,
kuturika simbi, yakakosha pasi waya, vibration damper, simbi dzezvombo, downlead clamp, majoini bhokisi uye zvichingodaro.
1. Kuiswa kwetension clamp
Tension clamp ndiyo kiyi Hardware yekuisa OPGW iyo isingangogadziri tambo padanda neshongwe uye inopa kudzvanywa kwakawanda asiwo inobata tambo zvakasimba asi isingapfuure kudivi rekumanikidza kweOPGW.Tension clamp inowanzo shandiswa mushongwe yekumisa, kona yekona inopfuura 15 °, iyo cabling.
shongwe kana shongwe yemusiyano mukuru we altitude.Iyo yakajairwa pre-stranding tension clamp inoumbwa newaya yemukati yakasungwa, yekunze tambo, thimble, bhaudhi, nati zvichingodaro.
Matanho ekuisa:
A. Gadzirisa hardware mushongwe mushure mekunge cable arc yagadziriswa ne putt-off equipments.
B. Dhonza tambo yekunze yetension yakasetwa kuburikidza nehana yakaita semoyo loop yehadhi yekufambisa.Ita tambo yetambo inoenderana netambo uye nyora tambo panzvimbo yekupenda pawaya.
C. Nyora waya yemukati ine mucherechedzo patambo, wobva wadzora boka rekutanga retambo yetambo.Reel dzimwe tambo dzisati dzasungirira kana isa chikafu chekudzika nechiratidzo chemavara kuti simbi dzese dzisati dzasungirirana dzichinanaira pamwe chete zvakasimba uye migumo yacho yakatemwa uye
zvakaenzana.Dzivirira pre-stranding waya kubva pakuchinjisa nekuwedzeredza kuitira kuti usakanganisa kureba kwemabhaudhi.
D. Isa tambo yepre-stranding muchombo uye uenderane nemucherechedzo wepamuchinjikwa wewaya yekunze ine mucherechedzo weruvara wewaya yemukati.Wobva wadzora waya yekunze.Chengetedza nzvimbo yacho symmetrical zvisinei nereel kubva kune chimwe chikamu kana maviri zvikamu.
2 Kuiswa kwesimbi yekumisa
Pre-stranding suspension clamp inoshandiswa kuturika tambo muzasi, iyo inoumbwa nemukati metambo waya, kunze kwetambo yetambo, rubber clamp, alloy ingot crust, bhaudhi, nati uye gasket.
Matanho ekuisa:
A. Maka panomiswa poindi yeOPGW wobva wadzora waya yemukati kubva pakati, iyo yamaka.Shandisa maoko kwete maturusi kudzoreredza chikamu chekumisa mushure mekutenderedza waya dzese dzemukati.
B. Isa pakati pemukati wewaya inosungirira pakati perabha clamp uye yakagadzika ne tepi yakatukwa, Uye wobva wadzora waya yekunze patambo yegororo pamwe chete necurve kana kuisa pasi Hake.Chengetedza nzvimbo yacho yakaenzana uye dzivirira kupindirana.
C. Isai pakati pekupwanya kusvika pakati petambo yetambo yekupedzisira kubvarura bhaudhi uye gadzirisa.Uye wozobatanidza neyakamiswa staple, bvarura bhaudhi uye urembera pashongwe.
3. Kuisa vibration damper
Vibration damper inoshandiswa kubvisa kana kusunungura kuzunguzika kunokonzerwa nemhando dzese dzezvinhu panguva yeOPGW kushanda kuitira kuchengetedza OPGW tambo uye kurebesa hupenyu hwetambo.
3.1 Kuisa nhamba yekugovera nheyo:
Nhamba yekudengenyeka damper inogoverwa maererano nenheyo inotevera: span≤250m: 2 seti;span: 250 ~ 500m (kusanganisira 500m), 4 seti;kureba: 500 ~ 750m (kusanganisira 750m), 6 seti;kana span yadarika 1000m, chirongwa chekugovera chinofanira kuchinjwa zvinoenderana nemamiriro emutsara.
3.2 Kuiswa chinzvimbo
(1) Computational formula:
Computational formula:
D: tambo dhayamita (mm)
T: tambo pagore avhareji kushushikana (kN), kazhinji 20% RTS
M: uremu hwetambo yetambo (kg/km)
(2) Nzvimbo yekutangira ye vibration damper kuisirwa: nzvimbo yekutanga yeL1 ndiyo yepakati mutsara wekusungirira clamp uye yepakati mutsara wetension clamp thimble;nzvimbo yekutanga yeL2 ndiyo yepakati pekutanga vibration damper, nzvimbo yekutanga yeL3 ndiyo yepakati yechipiri vibration damper, zvichingodaro.
(3) Yekutanga vibration damper inofanira kuiswa pane yemukati tambo waya yezvishandiso, nezvimwe.
akaiswa pamatanda akakosha ezvombo kubva kune yechipiri vibration damper.
4. Kuiswa kwevhu wire
Ivhu wire inonyanya kushandiswa kupa mukana kune magetsi mapfupi kana OPGW ichidzika.Yakasungwa newaya yealloy uye yakabatana nemidziyo ine parallel groove clamp kana mufananidzo uye imwe magumo yakabatana neshongwe yepasi gomba.Kuiswa kwewaya yepasi kunofanirwa kuve kwakanaka, nekureba kwakakodzera, pasina bend kana twist.Mapoinzi ekubatanidza anofanirwa kuve nemabatiro akanaka uye kuramba akabatana mukati
mitsetse yose.
5. Kuiswa kweiyo downlead clamp, cable tray uye joint box
Cable pane splicing point pashongwe inofanirwa kupatsanurwa mushure mekutungamira pasi.Padivi pemativi maviri epasi waya inomira yeshongwe kune shongwe muviri uye wozotungamira nemukati meiyo shongwe muviri.Kupeta radius yenzira iyo inodonhedza inopfuura haifanirwe kunge iri pasi pe1m, uye diki yekubhenda radius inofanirwa kuvimbiswa panguva yekushanda, kazhinji inodarika 0.5m.Mushure mekunge tambo yatungamira pasi, downlead clamp inoshandiswa kusungira iyo
tambo pamusimboti zvinhu kana zvimwe zvinhu zvetambo.Anchor ear type downlead clamp inofanirwa kushandiswa kana ichinge yaiswa mutobvu padivi rekongiri (yakadai
sekushandura chiteshi, simba rekudyara chimiro) .Cable downlead inofanira kuva yakatwasuka uye yakanaka.Joint box uye cable tray inofanirwa kuiswa panzvimbo yakakodzera pane shongwe, uye inenge 8 ~ 10m pamusoro peiyo datum pamusoro peshongwe.Kuiswa kunofanirwa kuve kwakasimba uye mitsetse yese inofanira kunge yakabatana.
