    Multi Mode PBT Type OPGW Optical Ground Wire Large Diameter And Fiber Capacity Fiber Optic Cable


    OPGW is a type of cable structure with composite of optical transmission and overhead ground wire for power transmission. Its working in power transmission line both as optical fiber cable and overhead ground wire which can provide protection of lightning strike and conducting short circuit currency.The OPGW consist of stainless steel tube optical unit, aluminum cladding steel wire, aluminum alloy wire. It has central stainless steel tube structure and layer stranding structure. We can design the structure according to different environment condition and customers requirements.


    Application


    1. Optical fiber composite ground wire [OPGW] is suitable for installation on new power lines with double function of ground wire and communication.

    2. Adapt to replace the aged ground wire and new structure of high voltage ground wire.

    3. lighting protection and conduct the short circuit current.

    4. Optical fiber communication ability.
