OPGW FAQS
Optical cable cov npoj yaig, yog leej twg nug dab tsiOPGW kho qhov muag cableyog, thov teb zoo li no:
1. Dab tsi yog cov qauv ntawm optical cables?
Cov qauv kho qhov muag ntawm cov khoom siv kho qhov muag muaj ob hom stranded hom thiab hom pob txha.
2. Lub ntsiab muaj pes tsawg leeg yog dab tsi?
Cov kab hluav taws xob kho qhov muag feem ntau yog tsim los ntawm: fiber core, optical fiber grease, sheath khoom, PBT (polybutylene terephthalate) thiab lwm yam ntaub ntawv.
3.Dab tsi yog armor ntawm optical cable?
Lub armoring ntawm optical cable yog hais txog cov khoom tiv thaiv (feem ntau steel hlau los yog steel daim kab xev) siv nyob rau hauv tshwj xeeb-lub hom phiaj kho qhov muag cables (xws li submarine optical cables, thiab lwm yam).Lub armor yog txuas rau sab hauv sheath ntawm optical cable.
4. Cov khoom siv dab tsi yog siv rau cable sheath?
Lub sheath los yog txheej ntawm optical cable feem ntau yog tsim los ntawm polyethylene (PE) thiab polyvinyl chloride (PVC) cov ntaub ntawv, thiab nws txoj haujlwm yog los tiv thaiv cov tub ntxhais cable los ntawm kev cuam tshuam sab nraud.
5. Dab tsi yog qhov tshwj xeeb optical cables siv hauv lub tshuab fais fab?
Muaj peb hom tshwj xeeb kho qhov muag cables siv hauv lub tshuab hluav taws xob: hauv av xaim sib txuas kho qhov muag cable (OPGW), qhov txhab kho qhov muag cable (GWWOP), thiab kev txhawb nqa tus kheej optical cable (ADSS).
Hauv av hlau sib txuas kho qhov muag cable (OPGW), cov khoom siv kho qhov muag tau muab tso rau hauv cov kab hluav taws xob ntawm cov hlau-clad aluminium strand qauv.Daim ntawv thov ntawm OPGW optical cable plays ob txoj haujlwm ntawm kev sib txuas lus hauv av thiab kev sib txuas lus, ua kom zoo dua qubKev siv tus nqi ntawm cov ncej fais fab yog nce.Qhwv qhov muag cable (GWWOP), qhov twg muaj cov kab hluav taws xob xa hluav taws xob, cov kab hluav taws xob kho qhov muag raug mob lossis raug tshem tawm ntawm cov xaim hauv av.Kuv hnov tias 6-core optical cable yog kim dua li 6-core optical cable, yog tias koj xav tau kev nkag siab ntau dua.Tus kheej txhawb nqa optical cable (ADSS) muaj zog tensile zog thiab tuaj yeem dai ncaj qha ntawm ob lub zog ncej nrog qhov siab tshaj plaws ntawm txog 1500m.
6. Dab tsi yog cov qauv siv ntawm OPGW optical cables?
Daim ntawv thov qauv ntawm OPGW optical cable feem ntau suav nrog: yas raj txheej stranding + txhuas raj qauv, nruab nrab yas raj + txhuas raj qauv, txhuas skeleton qauv, kauv txhuas raj qauv, ib txheejRusty steel yeeb nkab qauv, central stainless hlau yeeb nkab qauv, stainless hlau yeeb nkab txheej qauv, puas stainless hlau yeeb nkab qauv, central stainless hlau yeeb nkab qauv, stainless hlau yeeb nkab txheej qauv.
7. Dab tsi yog qhov tseem ceeb ntawm cov hlua khi sab nraud ntawm cov tub ntxhais cable?
Cov xaim xaim tawm sab nraud ntawm cov tub ntxhais ntawm OPGW optical cable yog tsim los ntawm AA hlau (txhuas hlau hlau) thiab AS hlau (txhuas hlau clad hlau).
8. Dab tsi yog cov txheej txheem rau kev xaiv OPGW cable qauv?
1) Lub nominal tensile zog (RTS) (kN) ntawm OPGW optical cable;
2) Tus naj npawb ntawm fiber ntau cores (SM) ntawm OPGW cable;
3) luv-circuit tam sim no (kA);
4) Lub sijhawm luv luv (s);
5) Qhov kub thiab txias (℃).
9.Yuav ua li cas kom txo tau qhov khoov degree ntawm optical cable?
Lub vojvoog dabtsi yog khoov ntawm cov khoom siv kho qhov muag yuav tsum tsis pub tsawg dua 20 npaug ntawm txoj kab uas hla sab nraud ntawm cov khoom siv kho qhov muag, thiab thaum lub sij hawm tsim kho (tsis nyob rau hauv lub xeev) yuav tsum tsis pub tsawg tshaj 30 npaug ntawm txoj kab uas hla ntawm optical cable.
10. Dab tsi yuav tsum tau them rau hauv qhov project?
Muaj peb lub tswv yim tseem ceeb hauv ADSS optical cable engineering: optical cable mechanical design, kev txiav txim siab ntawm cov ntsiab lus raug ncua, thiab kev xaiv thiab kev teeb tsa ntawm kev txhawb nqa kho vajtse.
11. Dab tsi yog qhov tseem ceeb ntawm kev kho qhov muag cable fittings?
Optical cable fittings xa mus rau cov cuab yeej siv los txhim kho qhov kho qhov muag cable, feem ntau suav nrog: lim clamp, ncua kev kawm ntawv clamp, vibration isolator, thiab lwm yam.
