OPGW optical cable is erected in the left side of the tower on the ground bracket. When the OPGW fiber optic cable is disconnected, it go all along the C tower under the lead, the connection box and the remaining cable rack should be installed in the tower from the ground 8m above the C-leg main component B-C leg left of the component (oblique or auxiliary material).

The minimum bending radius of OPGW optical cable is not less than 0.5m. After construction, the minimum bending radius shall not be less than the value required by the manufacturer,you must pay more attention when making jumpers, drawdowns and excess cables. Cable should be used to prevent twisting hammer OPGW optical cable rotation and take measures to prevent the traction rope torque transmitted to the OPGW cable.

When doing line-tightening,the tension should be maintained for one hour after reaching the designed value, to make the OPGW cable internal torsional stress disappear. OPGW cable line tightening process use tight line equipment and traction nets sets. When the tension is released, the tension of the OPGW optical cable meets the requirements of the guide and the spacing of the ground as far as possible so as to prevent damage to the optical fiber. The other requirements of the wiring are the same as those of the guidewire. OPGW fiber optic cable must be a (each plate) length for the pay-off section, not allowed to two or more OPGtW optical cable be installed after they were connected. The aluminum clad steel part of the OPGW cable can be cut by the traditional cutting method. However, the stainless steel tube on which the optical fiber is placed must be cut by the stainless steel cutter provided by the manufacturer. At the same time, care must be taken to avoid damage to the optical fiber during cutting. Connections are not allowe at anywhere of the OPGW line, except for the certained design of the connector. Therefore, OPGW should not be cut anywhere except in and out line box of the OPGW can be cut when it was required in the installation requirements. During tensioning, the end of the OPGW should be protected from damage as much as possible. The manufacturer of the OPGW needs to take charge of the related parameters of the entire OPGW line after the OPGW line connection or release. Therefore, the manufacturer will dispatch technicians to guide and supervise the OPGW release and connection process during the OPGW release process.

In the era of “Internet +”, for optical fiber and cable construction, ADSS optical cable, OPGW optical cable and other power cables are widely used in procurement, we may encounter many problems in construction and maintenance , so we must find a good optical fiber manufacturers.
