In a 500kV high-voltage transmission line project in the southwest region, ADSS optical cables need to cross a deep canyon of nearly 800 meters. The wind here is strong all year round and it is easy to freeze in winter, which poses a challenge to the suspension of optical cables. In response to this phenomenon, the transmission project adopted ADSS suspension clamps to solve it.

Preformed Helical Suspension Clamp is a common hardware for hanging optical cables on transmission line towers, and it plays an important role all the time. Preformed Helical Suspension Clamp is mainly used for connecting optical cables with straight towers or towers with an angle of less than 25°, one set for each tower. The wire clamp can reduce the static stress of the optical cable at the suspension point, improve the vibration resistance of the optical cable, and overcome the dynamic stress of wind vibration; it can also ensure that the bending of the optical cable does not exceed the allowed value, so as not to generate bending stress, thus ensuring that the optical fiber will not be lost.

From the cast iron clamps in the 19th century to the ship-shaped clamps in the 20th century, the evolution of power fittings stagnated for half a century. It was not until the emergence of preformed suspension clamps that the original way of hanging wires truly entered a new era.

Do you know? Under the dual pressure of increasing global electricity demand and carbon neutrality goals, what kind of technology can simultaneously improve grid reliability and promote green development? The preformed suspension clamp provides the answer. Why can this product improve? Why does it break the problem of conductor protection and become a benchmark for sustainable development in the power industry? The core technology of the pre-twisted spiral suspension wire clamp is mainly reflected in the following three aspects: compatibility, durability and functionality.

The preformed helical suspension clamp adopts a modular design. The installation process does not require complex tools, and construction workers can complete the installation quickly. This design not only greatly shortens the construction time, but also reduces labor costs to a certain extent. It is particularly suitable for rapid deployment in complex terrain.

With the rapid development of fiber optic communication technology, the helical suspension clamp for ADSS has become increasingly popular in both the power and communication industries. In this context, the helical suspension clamp for ADSS, as a key device for ensuring the stable operation of optical cables, has gradually become an indispensable part of the power industry. Made from lightweight materials, the helical suspension clamp for ADSS effectively reduces the load on towers and conductors, while also being easy to transport and install, greatly improving construction efficiency.
