　　OPGW fiber optic cable manufacturer OPGW power communication fiber optic cable

　　OPGW fiber optic cable product introduction:

　　OPGW optical cable, also known as fiber optic composite overhead ground wire, generally adopts aluminum tube type, aluminum skeleton type, and (stainless) steel tube type structures. The structure of OPGW optical cable is to embed 250 μ m optical fibers into a stainless steel sleeve, wrap aluminum clad steel wire (ACS wire) around the sleeve, and wrap the outer layer with aluminum alloy wire (AA wire) to form a cable.

　　Characteristics of OPGW optical cable products:

　　Adopting advanced stainless steel tube production technology, the tube is filled with water-resistant compounds, which can effectively protect the optical fiber;

　　Good compactness and high tensile strength;

　　Short circuit current causes minimal interference between the power grid and communication network;

　　The excess length of the optical fiber and the twisted pitch of the cable core ensure that the OPGW optical cable is not subjected to force during operation tension;

　　Similar to commonly used ground wire specifications, it is very convenient to install and can directly replace the original ground wire.

　　OPGW fiber optic cable application:

　　1. OPGW optical cables are mainly used on 110KV, 220KV, and 550KV voltage level lines. Due to factors such as power outages and safety, they are often applied on newly built lines.

　　2. Lines with high voltage exceeding 110kV have a large span (usually above 250M).

　　3. Easy to maintain, easy to solve for line crossing problems, and its mechanical characteristics can meet the requirements for large line crossings.

　　4. The outer layer of OPGW is metal armor, which has no effect on high-voltage corrosion and degradation.

　　5. OPGW must be powered off during construction, and the losses caused by power outages are significant. Therefore, OPGW should be used in the construction of new high-voltage lines above 110kV.
