Description of a OPGW
OPGW optical cable is to place the optical fiber in the ground wire of the overhead high-voltage transmission line to form the optical fiber communication network on the transmission line. This structure has the dual functions of ground wire and communication. The optical power ground wire is more reliable, stable and firm due to the metal wire wrapping. Because the overhead ground wire and the optical cable are combined as a whole, compared with other methods of optical cables, the construction period is shortened and the construction cost is saved.
OPGW Optical Cable Characteristics & Advantage
Using good stainless steel tube production technology, the tube is filled with water blocking compounds, which can effectively protect the optical fiber
Good compactness and high tensile strength
The short-circuit current has little mutual interference between the power grid and the communication network
Similar to the common ground wire specifications, it is very convenient to erect and can directly replace the original ground wire.
OPGW Mainly used for power communication with accessories,relay protection,automatic transmission,installation together with high-voltage lines.
The Stranded Optical Ground Wire (OPGW) is stranded by double or three layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires, Its design is fully adapted to the most common electric line needs.
