Sab nraum zoov Optical Cable Structure thiab Technology

Sab nraum zoov kho qhov muag cable yog ib hom kev sib txuas lus kab tsim los rau kev sib kis ntawm cov teeb liab kho qhov muag; nws muaj ib tug xov tooj ntawm optical fibers teem nyob rau hauv ib tug tshwj xeeb configuration los tsim ib tug cable core, uas yog ces encased nyob rau hauv ib tug sheath-qee zaum nrog ntxiv ntawm ib tug txheej tiv thaiv.
Nws tsim ua raws li lub hauv paus ntsiab lus ntawm ib puag ncig adaptability, tshwj xeeb tshaj yog "Peb Kev Tiv Thaiv thiab Ob Qhov Kev Tiv Thaiv": kev tiv thaiv dej, noo noo, thiab corrosion, thiab tiv taus tensile thiab compressive zog. Kev tiv thaiv dej yog ua tiav los ntawm kev tsim qauv ntawm ob lub- txheej txheem: cov tub ntxhais cable tiv thaiv dej nkag los ntawm PBT cov raj xoob ntim nrog dej- thaiv cov gel, thaum txheej txheej sab nrauv ua kom cov dej tsis sib haum los ntawm kev siv high- ntom polyethylene (HDPE) los yog cov khoom sib txuas ntawm txhuas-polyethylene sheath Xwb, "tag nrho-qhuav" thev naus laus zis siv dej qhuav- thaiv cov ntaub ntawv- xws li dej- cov xov paj swellable, hmoov, los yog daim kab xev- los hloov cov tsoos gel filling.

Kev tiv thaiv kev siv tshuab yog tsim los rau cov txheej txheem kev teeb tsa sib txawv: ncaj qha - faus cables siv steel daim kab xev lossis steel hlau armoring los tiv thaiv sab nraud; aerial cables siv tus kheej-txhawb "daim duab-8" qauv-muaj peev xwm nruab nrog kev co dampers- txhawm rau txhim kho lawv qhov tsis kam rau tensile kev nyuaj siab thiab cua loads; thiab duct cables feem ntau feature cov qauv xws li lub hauv paus xoob raj tsim, feem ntau ntxiv nrog aramid yarns. Kev tiv thaiv kab mob muaj xws li kev siv cov iav fiber ntau lossis cov hlau tsis muaj steel hlau rau hauv lub hnab los tiv thaiv cov nas tsuag, lossis ntxiv cov tshuaj tiv thaiv -cov kab mob- lossis siv Nylon 12 sheath- txhawm rau tiv thaiv kab tsuag. Kub adaptability yuav tsum tau cov ntaub ntawv sheath kom khaws nws yooj yim nyob rau hauv qhov chaw txias heev -piv txwv li, los ntawm kev siv tsawg-kub hloov polyethylene sheaths-thaum kuj xav txog thermal hluav taws xob nyob rau hauv high-temperature ib puag ncig los ntawm kev koom ua ke ntawm additives xws li carbon dub masterbatch.
