Helical-formed suspension clamp is used to connect various conductors such as ADSS optical cable and OPGW optical cable on straight pole towers, and is used for the suspension conductors and ground wires of pole towers. Helical-formed suspension clamp can effectively protect the conductors, assist in vibration reduction, and can well extend the service life of the wire line. So do you know what other characteristics and advantages it has?

Although the production cost of Preformed fittings is slightly higher than that of traditional power fittings, in the long run, the use of Preformed fittings can greatly reduce the operating cost of the line. Do you know what Preformed fittings are? What are their functions?

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.

The suspension clamp is mainly used for overhead power lines or substations. The conductor and lightning conductor are suspended on the insulator or the lightning conductor is suspended on the tower through the connection hardware. It can also be used to support the transposition conductor on the transposition tower and fix the non-linear tower jumper. The suspension clamp is used to suspend or support the conductor, and is mainly a hardware that bears vertical loads.

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.
