From the point of view of the functional nature, the main role of suspension clamp for OPGW cable is to realize the reliable connection and load transfer of OPGW optical cable and tower. During the operation of the transmission line, the OPGW optical cable needs to withstand the thermal expansion and contraction stress caused by its own weight, wind load, icing load and temperature changes for a long time. If the fixture connection stability is insufficient, the light will cause the OPGW optical cable to produce excessive sagging or displacement, affecting the communication signal transmission quality, and the heavy will cause the OPGW optical cable to break, causing regional power communication interruption and lightning protection failure of the transmission line. Through the optimized clamping structure design, the high-quality suspension clamp for OPGW cable can provide a stable grip without damage to the outer sheath of the OPGW cable, and evenly transmit all kinds of dynamic and static loads to the tower to avoid structural damage to the OPGW cable caused by local stress concentration.
At the same time, suspension clamp for OPGW cable also assumes the role of ensuring the stable operation attitude and communication performance of OPGW cable. The optical fiber inside the OPGW optical cable has strict requirements for bending radius and vibration frequency. When the bending radius is less than the design threshold, the attenuation of the optical fiber signal will increase significantly, and long-term high-frequency vibration may cause the optical fiber connector to loose and cause communication interruption. Suspension clamp for OPGW cable through the built-in elastic buffer assembly and limit structure, it can effectively absorb the energy generated by wind vibration, and control the vibration amplitude of the OPGW cable within 0.5mm. At the same time, through precise installation and positioning, the OPGW cable can always maintain the arc and direction that meet the design requirements, and avoid excessive bending of the optical fiber due to attitude offset.
In addition, the weather resistance and corrosion resistance to complex outdoor environments are also one of the functions of suspension clamp for OPGW cable. Transmission lines usually pass through harsh environments such as mountains, coasts, and deserts. High temperature, high humidity, salt spray, strong ultraviolet rays, and industrial pollutants will cause serious erosion of the fixture material. If the fixture is corroded or the structure is aging, it will not only lose its carrying capacity, but may also produce rust products that pollute the outer sheath of the OPGW optical cable, accelerating aging. Therefore, high-quality suspension clamp for OPGW cable is usually made of high-strength alloy materials and surface treatment processes such as hard anodizing, hot-dip galvanized or fluorocarbon spraying, which have excellent salt spray resistance and high and low temperature resistance.
