The connection part of the wire and the fittings is the key area for the installation of spiral vibration damper, because this part is the place where the vibration stress of the wire is most concentrated. When the wire vibrates, the metal fittings as the fixed end will limit the displacement of the wire, resulting in greater bending stress and fatigue damage at the connection between the wire and the metal fittings. This is also a high-incidence area of wire strand failure. Therefore, spiral vibration damper is usually installed on both sides of the wire close to the fittings, and the specific distance needs to be determined according to the type of fittings and the diameter of the wire.

From the point of view of installation convenience, the easy-to-use ADSS dead end tension clamp should have the characteristics of lightweight, modular, and easy to operate, and can be installed without complex tools and professional skills.

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.
