Cov Kev Pab Tau Los Ntawm LSZH Jacked Cables
Yog tias kev tiv thaiv cov khoom siv lossis cov tib neeg yog qhov tsim qauv tsim, xav txog cov pa taws tsawg xoom-halogen (LSZH) jacketed cables. Lawv tso tawm cov pa phem tsawg dua li cov txheej txheem ntawm cov xov tooj cua PVC. Feem ntau, LSZH cable siv rau hauv cov chaw kaw xws li kev ua haujlwm mining qhov chaw tso pa tawm yog qhov muaj kev txhawj xeeb.
Dab tsi yog qhov sib txawv ntawm LSZH cable thiab cable ntau?
Kev ua haujlwm thiab txheej txheem ntsuas ntawm LSZH fiber ntau kho qhov muag hluav taws xob zoo ib yam li fiber ntau cov kab ua ke, thiab sab hauv qauv kuj zoo ib yam, qhov sib txawv yooj yim yog cov tsho. LSZH fiber ntau cov hlua hluav taws xob muaj hluav taws kub ntau dua li piv nrog cov sib xws PVC jacketed cables, txawm tias thaum lawv ntes tau hluav taws, cov hluav taws kub LSZH cable muab cov pa taws qis thiab tsis muaj cov tshuaj halogen, qhov no tsis tsuas yog tiv thaiv ib puag ncig tab sis cov pa luam yeeb tsawg thaum nws tau txais hlawv kuj tseem ceeb rau tib neeg thiab cov chaw hauv qhov chaw tua hluav taws.
LSZH tsho tsho hnav yog ua los ntawm qee cov ntaub ntawv tshwj xeeb heev uas tsis cuam tshuam txog cov nplaim hluav taws thiab nplaim taws. LSZH cable tsho khawm tsho ua ke ntawm cov thermoplastic lossis cov thermoset sib txuas uas tawm cov pa luam yeeb thiab tsis muaj halogen thaum raug rau cov pa taws ntau. LSZH cable txo qhov ntau ntawm cov kuab lom thiab corrosive roj tawm thaum hlawv. Hom khoom siv no feem ntau siv rau qhov chaw tsis zoo xws li lub dav hlau lossis tsheb ciav hlau. LSZH cov tsho loj kuj tseem muaj kev nyab xeeb dua dua li Plenum-rated cable plev uas muaj cov nplaim taws tsis tshua zoo tab sis tseem tso tawm cov pa phem thiab cov pa thaum lawv hlawv.
Tsis tshua muaj neeg haus luam yeeb xoom halogen yog ua nrov heev thiab, muaj qee qhov, qhov yuav tsum tau muaj kev tiv thaiv ntawm tib neeg thiab khoom siv los ntawm cov tshuaj lom neeg thiab xeb yog qhov tseem ceeb. Hom hluav taws xob no puas tau koom nrog hluav taws kub nyhiab me me yog tsim los ua cov cable no ua rau kev xaiv zoo rau cov chaw ruaj khov xws li nkoj, nkoj xa hauv av, dav hlau, chav ua haujlwm siab ua haujlwm thiab lub chaw xaib.
Txhua lub nyiaj muaj ob sab. Txij li LSZH cables muaj ntau cov txiaj ntsig tau teev rau saum toj no, Dab tsi yog qhov Cons ntawm lub cable?
1. LSZH yooj yim dua rau lub tsho plev. Cov tshuab roj av tshwj xeeb tau tsim kom txo kev puas tsuaj thaum lub sijhawm teeb tsa.
2. Lub tsho LSZH muaj qhov sib txuam siab cov ntsiab lus, ib ncig 50% kom muab cov nplaim uas xav tau thiab cov pa luam yeeb ua haujlwm. Qhov no ua rau qis dua kev siv tshuab, tshuaj tsis kam, kev nqus dej thiab cov khoom siv hluav taws xob tom qab ntawd tsis yog LSZH lub tebchaw.
3. Lub tshuab hluav taws xob tam sim no ntawm LSZH hluav taws xob tseem tsis tau tsim cov ntaub ntawv pov thawj keeb kwm ntawm kev ua haujlwm ntev.
LSZH cov kab hluav taws xob muaj nrog 1, 2, 12, 24 roj teeb, thiab kuj tsis paub meej sub-cable qhov ntev uas txhawb rau kev txiav tshwj xeeb thiab kev hla kev. Lawv haum rau halogen dawb thiab ntau thoob ntiaj teb kev teeb tsa. LSZH cable tsis muaj qhov dej nyab gel thiab yog OFNR Riser rated, yog qhov zoo tshaj plaws rau kev teeb tsa hauv kev sib txuas ntawm cov tsev thiab khiav ncaj qha rau cov risers mus rau qhov yooj yim network lossis dome fiber optic splice kaw tsis muaj qhov sib cais ntawm txaws ntawm lub tsev nkag.
Tseem muaj LSZH fiber ntau optic thaj hluav taws xob muaj. Ob lub LSZH fiber ntau kho qhov muag thiab LSZH fiber ntau kho qhov muag kab yuav tsum rau Rosh raws txoj kab hluav taws xob sib dhos, tab sis Rosh tus qauv nruj dua li nws xav tau cov cables ua LSZH hom. LSZH fiber ntau cov khoom siv dav siv nyob rau hauv qhov chaw uas cov khoom siv kim yuav raug puas ntsoog yog tias raug cov roj paug, thiab lawv tseem siv nyob hauv thaj chaw muaj neeg coob nyiam chaw lag luam thiab chaw kis las.
