Optical Power Ground Wire (OPGW Cable)
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.
Fiber Type: G652D; G655C; 657A1; 50/125; 62.5/125; OM3; OM4 As Options
Fiber Count: Up to 96 Cores
Applicable Voltage Range: Power lines with voltage level of 110KV and below.
Applications: Commonly used in newly built overhead power lines. Can meet the
requirements of big number of fibers and ultra high
voltage(UHV)transmission lines. Can provide protection against
lightning by transmitting large fault short-circuit current
