The working logic of ADSS dead end tension clamp is a balance between safely transmitting tension and protecting the optical cable from damage.

​The corona effect is a special discharge phenomenon under a high-voltage electric field. When the line voltage rises to a certain extent, the charge density on the surface of the wire increases abruptly, especially at the tip, joint or burr, the electric field strength will be quickly concentrated.

From the point of view of structure and material, the guard line is made of multiple strands of high-strength aluminum alloy prefabricated into a spiral structure. Each strand is heat-treated and formed, which can make the spiral arc and the outer diameter of the wire highly match. This preformed design is different from the traditional rigid wire protection fittings. Its flexible structure can closely fit the surface of the wire to avoid the local stress concentration of the wire caused by rigid contact.

​From the functional point of view, the main role of suspension clamp for OPGW cable is to achieve reliable connection and precise positioning between the OPGW optical cable and the transmission tower.

The main purpose of corona ring coil​ is to suppress the corona discharge phenomenon of high-voltage equipment and protect the insulation system of the equipment from the root cause. The secondary purpose of corona ring coil is to reduce energy loss and electromagnetic interference and improve the overall energy efficiency of the transmission system. In addition, the use of corona ring coil in simplifying the operation and maintenance process and reducing long-term operating costs is in line with the pursuit of project economy by B-side buyers.

From the definition point of view, suspension clamp for OPGW cable is a mechanical connection device specially designed for OPGW optical cable. By cooperating with the metal fittings system on the transmission line pole tower, the optical cable is fixed at the designated location of the pole tower. At the same time, it needs to meet the various requirements of mechanical stress, environmental adaptability and communication performance of the optical cable in long-term operation.
