Cov Kev Pab Tau Los ntawm LSZH Jacked Cables
Yog tias kev tiv thaiv cov cuab yeej los yog cov neeg yog qhov yuav tsum tau tsim, xav txog kev haus luam yeeb tsawg tsawg xoom-halogen (LSZH). Lawv tawm cov pa luam yeeb tsawg dua li PVC-raws li tsho. Feem ntau, halogen dawb kab yog siv nyob rau hauv cov chaw sib txuam xws li kev lag luam cov mining qhov twg qhov kev nyab xeeb yog kev txhawj xeeb.
Dab tsi yog qhov txawv ntawm LSZH cable thiab hom cables?
Qhov kev ua haujlwm thiab cov txheej txheem parameter ntawm LSZH fiber optic cable yog ib yam li cov fibre fiber ntau, thiab cov qauv puab kuj zoo sib xws, qhov sib txawv yooj yim yog cov tsho loj. LSZH fiber optic Jackets ntau dua hluav taws xob uas tiv thaiv nrog cov kab mob PVC pcs, txawm tias thaum lawv raug ntes nyob rau hauv hluav taws, cov kab mob LSZH muab cov pa uas tsis tshua muaj thiab tsis muaj halogen tshuaj, qhov no tsis yog ib qhov chaw tiv thaiv tab sis cov pa tsis tshua muaj thaum nws tau Kub tuag tseem ceeb heev rau cov neeg thiab cov chaw hauv qhov chaw raug rho tawm haujlwm.
LSZH lub tsho muaj ua los ntawm qee cov ntaub ntawv tshwj xeeb uas tsis yog-halogenated thiab nplaim hluav taws. LSZH cable jacketing yog tsim los ntawm thermoplastic lossis thermoset compounds uas luam tawm cov pa luam yeeb thiab tsis muaj halogen thaum raug mus rau qhov chaw siab ntawm tshav kub. LSZH cable txo cov roj teeb meem thiab cov pa roj tawm thaum lub sijhawm hluav taws xob. Cov khoom siv no feem ntau siv hauv cov chaw tsis muaj pa xws li dav hlau los yog kev tsheb nqaj hlau. LSZH lub tsho tseem muaj kev ruaj ntseg tshaj Plenum-ntsaws cable tsho uas muaj qhov kub tsis txaus, tiam sis tseem tso cov pa phem thiab cov pa luam yeeb thaum lawv raug kub hnyiab.
Kev haus luam yeeb tsawg pes tsawg lub halogen yog ua nrov heev thiab, qee zaum, qhov uas yuav tsum muaj kev tiv thaiv cov neeg thiab khoom siv los ntawm kev ua pa thiab cov pa roj ntsha yog qhov tseem ceeb. Hom kab xov tooj no puas muaj kev cuam tshuam rau hluav taws kub me me heev uas ua rau cov kab no zoo tshaj plaws rau qhov chaw xws li nkoj, submarines, dav hlau, chav sib txuas chav sib txuas thiab cov chaw zov me nyuam.
Txhua npib muaj ob sab. Txij li thaum LSZH cables muaj ntau cov kev pab cuam tau teev tseg saum toj no, cov Cons ntawm lub cable yog dab tsi?
1. LSZH muaj feem ntau raug rau lub tsho tawg. Cov roj ntsha tshwj xeeb tau tsim los txo qhov kev puas tsuaj thaum lub sijhawm teeb.
2. LSZH lub tsho muaj cov ntsiab lus loj, ib nrab ntawm 50% los muab cov nplaim taws thiab kev haus luam yeeb. Qhov no ua rau qis dua txhua yam, tshuaj lom neeg ua haujlwm, dej haus thiab hluav taws xob cov khoom ces tsis yog LSZH compounds.
3. Cov cim tam sim no ntawm LSZH cables tseem tsis tau tsim ib qho keeb kwm pov thawj ntawm kev ua tiav ntev.
LSZH cables muaj nyob nrog 1, 2, 12, 24 fibers, thiab cov kab mob qis dua qhov ntev uas txhawb qhov kev txiav tawm thiab kev yuav tsum ua raws li kev cai. Lawv tsim nyog rau halogen dawb thiab ntau lub thoob ntiaj teb. LSZH cable tsis muaj cov gel dej nyab thiab yog OFNR Riser ntsuas, zoo meej rau kev txhim kho hauv cov tsev thiab khiav ncaj qha mus rau lub chaw yooj yim los sis lub dome fiber optic splice kaw tsis muaj ib qho chaw cais ntawm lub tsev nkag.
Tseem muaj LSZH fiber optic thaj cords. Ob lub LSZH fiber optic cables thiab LSZH fiber optic thaj hlua yuav tsum rau Rosh raws kab ke sib txuas, tiam sis Rosh txheem dua nruj dua nws yuav tsum tau cov cables los ua hom LSZH. LSZH fiber ntau lub nplais yuav siv ntau qhov chaw uas cov cuab yeej cuab kim yuav raug puas tsuaj yog tias muaj cov roj ntsha corrosive, thiab lawv kuj siv rau thaj chaw ntau xws li chaw lag luam thiab chaw ua si.
