The ADSS suspension unit is an important supporting device specially used to fix and support ADSS optical cables in the field of power communications. The ADSS suspension unit can stably suspend the ADSS optical cable on the pole tower of the high-voltage transmission line, while assuming the tension of the optical cable and resisting interference from the external environment, so that the optical cable can maintain a stable position and smooth signal transmission during long-term operation. It is an important tool for connecting transmission poles and ADSS optical cables. It is widely used in high-voltage power grids, cross-regional communication lines and other scenarios, which are of great help to the safe and reliable operation of power communication systems. In this article, let us understand the ADSS suspension unit from the two aspects of composition and working principle!
From the point of view of composition, the ADSS suspension unit is not a single structural part, but a systematic device composed of multiple functional components. Each component has a clear division of labor to achieve stable suspension of optical cables. The components are clamping bodies made of high-strength aluminum alloy or engineering plastics, which have good corrosion resistance and aging resistance. The interior is provided with curved grooves that match the outer diameter of the ADSS optical cable. Rubber or silicone cushions will be laid in the grooves, which can not only closely fit the outer sheath of the optical cable, prevent the optical cable from sliding in the fixture, but also buffer the extrusion stress of the fixture on the optical cable, and prevent the outer sheath of the optical cable from being damaged due to long-term force. And suspension components, mainly including connecting parts such as hanging plates, bolts, nuts, etc., are used to connect the entire fixture to the horizontal load or other fixed structure of the transmission pole tower. The design of the hanging plate needs to meet the load-bearing requirements. Models of different strengths are usually selected according to the tension level of the optical cable. Bolts and nuts are designed to prevent loosening, such as installing spring washers or using lock nuts to prevent long-term wind and vibration from loosening the connecting parts. As well as adjustment devices, some ADSS suspension units will be equipped with adjustment bolts or chute structures, which can fine-tune the position height or horizontal angle of the fixture according to the actual installation needs, so that multiple optical cables are neatly arranged on the tower to prevent the optical cables from rubbing against each other or being damaged due to uneven force.
The working principle of the ADSS suspension unit revolves around carrying and protection. When the ADSS optical cable is installed, the optical cable must first be placed in the arc groove of the clamping body, and the clamping body is tightened by bolts, so that the cushion tightly wraps the optical cable, forming a firm clamping force to prevent the optical cable from sliding axially or radially. Then the fixture and the tower are fixed through the suspension assembly. At this time, the fixture needs to withstand various external forces such as the weight of the optical cable itself, wind load, ice and snow load, etc. The high-strength material of the clamping body and the suspension assembly will evenly transmit these external forces to the tower to prevent the optical cable from breaking due to excessive local force. At the same time, the adjustment device can correct the installation deviation, so that the optical cable has been within the designed force range during long-term operation, and ensure the stable performance of the fixture and the optical cable.
In short, the ADSS suspension unit is a very important supporting device in the ADSS optical cable system. The fixture can realize the stable suspension and safety protection of optical cables in complex environments.
