Unitube (Central Loose) Intambo yangaphandle GYXTW

GYXTW (metal strengthening member, steel-polyethylene bonded sheath with steel wire entrained, central beam tube type full-filled outdoor optical cable for communication) The structure of the optical cable is to place the loose tube in the center of the cable, and the single-mode optical fiber is sheathed by the A loose tube made of high modulus plastic filled with waterproof compound. The loose tube is longitudinally wrapped with water-blocking tape and steel belt, and the two sides of the cable core are polyethylene sheathed with two parallel steel wires as reinforcements.

    Izinto zokupakisha: Umgqomo wamaplanga
    Ubude bokupakisha: ubude obuqhelekileyo bekhebula buya kuba zi-2 km. Obunye ubude beentambo buyafumaneka
    ukuba iyafuneka ngabathengi

     

    Ukumakishwa kwentambo kunye nokuphawulwa kwentambo 

    Ishebhu yentambo iya kuphawulwa ngoonobumba abamhlophe ngokweemfuno zomthengi.
