Application:
Optical fiber composite ground wire (OPGW), as an advanced communication mode of power system and with unique advantages, has been widely laid in the old and new Lines in our country.
Construction:
OPGW has distinct features as follows
♦ 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

♦ The above parameters of the optical cable are only for the reference of the project units and the Design Institute, different manufacturers have different production process and calculation method, which would have a slight impact on the parameters.
♦ The number of fiber in the above cable parameters is the maximum number of the fiber contained by this structure, and the model of the fiber can be B1, B4 or B1+B4 (B1:G.652; B4:G.655).
♦ Only when the outer layer is made of aluminum clad steel (20.3 % IACSI~the diameter is not less than 3.2mm, 40 % lACSI-the diameter is not less than 3.2mm), the lightning resistance can be accepted as the minimum guaranteed value in accordance with 150C.
