Sab nraum zoov Direct Buried Ob Chav Armored Fiber Optic Cable

Aipu-waton GYTA53 optical cable yog ncaj qha faus ob chav armored fiber optic cable nrog ob daim kab xev hlau thiab ob txheej ntawm PE sheath. Nws txhais tau hais tias qhov fiber ntau optic cable muaj qhov zoo sab crush kuj ua tau zoo thiab kev sib koom tes. Cov yas steel daim kab xev (PSP) longitudinal pob zoo txhim kho cov dej noo tsis kam ntawm optical cable. Nyob rau hauv tas li ntawd, hom ntawm optical cable yog yooj yim dua siv nyob rau hauv ncaj qha faus cabling ib puag ncig. GYTA53 ncaj qha faus optical cable txais cov txheej txheem xoob xoob. Cov fiber ntau optical yog lub tes tsho rau hauv lub tes tsho xoob ua los ntawm cov khoom siv polyester siab, thiab lub tes tsho yog ntim nrog cov dej tsis sib haum. Lub raj xoob (thiab cov hlua txhaws) yog twisted nyob ib ncig ntawm lub hauv paus uas tsis yog-metallic reinforcing core (phosphated steel hlau) los tsim ib lub compact cable core, thiab qhov sib txawv ntawm cov tub ntxhais cable yog ntim nrog dej thaiv cov tshuaj pleev. Tom qab yas coated txhuas sawb (APL) yog longitudinally qhwv, ib txheej ntawm polyethylene puab sheath (PE) puab sheath yog extruded, thiab ces ib txheej ntawm cov dej resisting txheej yog ntxiv dag zog. Tom qab ntawd, ob sab yas coated steel sawb (PSP) yog longitudinally qhwv, polyethylene PE sheath yog extruded los ua ib tug cable.
