The working principle of suspension clamp for OPGW cable is to achieve reliable fixation and flexible protection of optical cables in a dynamic force environment. Unlike ordinary overhead line clamps that only need to bear vertical loads, OPGW optical cables also carry communication signal transmission functions. The internal optical fibers are very sensitive to external forces such as stretching, bending, and vibration. Therefore, the working process of suspension clamp for OPGW cable needs to meet three needs at the same time. The first is load carrying, which needs to stably withstand the weight, icing weight and wind load of the OPGW optical cable, so that the optical cable can maintain a constant arc sag between the poles and towers, and avoid stretching and deformation of the optical cable due to the movement of the load carrier. The second is displacement compensation. Due to the temperature difference between day and night and seasonal changes, the thermal expansion and contraction of the optical cable will be caused by the change of seasons. The fixture needs to have the ability to adjust the micro-displacement. Without changing the fixed stability, the temperature stress is released to prevent the optical cable from being overstretched or squeezed due to thermal expansion and contraction. The third point is optical fiber protection. The contact parts of the fixture and the optical cable need to adopt a special structural design to avoid local stress concentration and damage the outer sheath of the optical cable and the internal optical fiber. At the same time, it is isolated from corrosive media such as rain, sand and dust from the outside world to ensure the stability of communication signal transmission.
In fact, the workflow of a set of high-quality suspension clamp for OPGW cable in actual working conditions needs to be supported by a variety of technical designs. When the optical cable is erected, the fixture is connected to the tower through a hoop-type fixed structure to make it firmly installed. The optical cable is fixed through the elastic liner and adjustable briquettes inside the fixture. The elastic liner is made of silicone rubber that is resistant to aging and wear. It can not only increase the friction with the optical cable, prevent the optical cable from sliding in wind vibration, but also buffer the impact of external forces. The adjustable briquettes can be fine-tuned according to the outer diameter of the optical cable, so that the clamping force is evenly distributed to avoid excessive local pressure damaging the optical cable. When dealing with wind loads, the anti-vibration components of the fixture will play a role, absorbing wind vibration energy through the built-in damper, reducing the fatigue damage caused by high-frequency vibration of the optical cable, and when the temperature change causes the optical cable to shrink, the sliding connection structure of the fixture will allow the optical cable to be slightly displaced along the axial direction, while maintaining radial fixation, effectively releasing temperature stress, and avoiding signal attenuation or fracture of the optical fiber due to excessive stretching. In addition, the shell of the fixture is made of high-strength material, which can resist bad weather erosion after anti-corrosion treatment, so that the suspension clamp for OPGW cable can work stably for a long time in environments such as high temperature, high humidity, and salt spray.
