    Optical Fiber Cable (OPGW)

    INQUIRY MESSAGE

    OVERVIEW

    OPGW or known as Optical Ground Wire is a type of cable or wire that is used in transmission lines construction. It is also known as optical fiber composite overhead ground wire. It can serve as a grounding wire, shielding wire, and at the same time a cable used for communication purposes.

    STANDARD

    IEC 60794, IEEE 1138 Standards

    Description

    OPGW CABLE

    OPGW contains a tubular structure with one or more optical fibers in it. It is then surrounded by layers of steel and aluminum wire. It can be compared like an ASCR, except that steel is the one covering the tube with fiber optics inside.

    OPGW have the characteristic that there is no effect of high voltage induction on the data being transmitted through the Fibers. Hence this characteristic of the Fiber is taken into advantage to transmit the data along the high power transmission lines.

    Features

    It has double functions as ground wire and communication optical cable, and eliminates the huge cost of repeat erection.
    It is installed on the top of the aerial power line tower, there is no need to consider the best hanging point or electrocorrosion.
    In the transformation process of the old line, the diameter of the optical cable and pull-weight ratio can match well with another earth wire.
    Large transmission capacity, high communication quality and good reliability.
    Excellent mechanical and electrical property
    Good security property, long service life, and hard to be damaged by gun shot
