Before officially entering the installation process, it is necessary to confirm the installation environment and working conditions of corona ring coil. The construction team needs to verify key parameters such as the voltage level of the line to be installed, the type of insulator string, and the specifications of the fittings. It also needs to evaluate the on-site construction environment to ensure that the purchased corona ring coil is fully adapted to the on-site equipment and construction environment.

Preliminary preparations must be made before using suspension clamp for OPGW cable, which is the basis for ensuring the quality of subsequent installations. When entering the actual installation process, it is necessary to strictly follow the standardized operating logic to avoid damage to the OPGW optical cable. Debugging and inspection after the installation is completed are important steps to verify the effectiveness of the fixture and eliminate hidden dangers.

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.
