　　Common OPGW structures

　　There are three main types: aluminum tube type, aluminum frame type, and (stainless) steel tube type.

　　The installation design of OPGW should consider the coordination with wire stress, sag, and insulation clearance, and its load should not exceed the allowable range of use of the current tower and foundation. Therefore, the characteristic curve of the selected OPGW should be calculated based on its main technical parameters, and the layout, appearance, and installation drawings of the junction box, various fittings, and accessories should be designed in combination with the actual engineering situation.

　　1. Treatment of initial elongation

　　For the treatment of initial elongation of OPGW, the cooling method can be used, which involves reviewing the aluminum steel ratio of OPGW and referring to the cooling values of similar conductors or ground wires to handle its initial elongation.

　　2. Design of anti vibration measures

　　Among the fittings used in conjunction with OPGW, the tension clamp is of the pre twisted wire type, and the suspension clamp is equipped with pre twisted wire and rubber pads. These two fittings have a certain degree of anti vibration capability. To further enhance the anti vibration capability, it is possible to consider installing anti vibration hammers, which are generally calculated based on the span:

　　When the span is ≤ 300M, install an anti vibration hammer;

　　When the span is greater than or equal to 300M, install two vibration dampers.

　　3. Precautions for OPGW construction and installation

　　The construction and installation of OPGW is different from ordinary steel strands, and attention should be paid to preventing damage to avoid affecting the performance of optical fibers in the future. Special consideration should be given to the torsion, micro bending, local radial pressure outside the wire clamp, and pollution of optical fibers in OPGW.
