In power transmission, the stable suspension of wires is very important. This is not only related to the stable supply of electricity, but also to the safe operation of the entire power grid. However, traditional wire suspension methods often face many problems, such as complex installation, insufficient grip, and large damage to the wires. These problems seriously affect the transmission efficiency and the service life of the line. However, after reading this article, you will know an important tool for solving problems.
Helical-formed suspension clamp is mainly composed of preformed wire, rubber lining and coupling fittings. The preformed wire is mostly made of aluminum alloy or galvanized steel wire, which is tightly bonded to the wire by a special spiral winding method, which can effectively disperse the stress on the wire. The rubber lining acts as a buffer against pressure and prevents the wire from being damaged by direct force.
From the structural point of view, the preformed wire design of the helical-formed suspension clamp greatly increases the contact area between the clamp and the wire. Taking the traditional U-bolt style ship-shaped clamp as an example, the contact points between the ship-shaped clamp and the wire are relatively concentrated. During long-term use, it is easy to cause excessive local stress, resulting in wear and even fracture of the wire. The preformed wire of the helical-formed suspension clamp is evenly wound on the wire, dispersing the stress to the entire contact area, greatly reducing the risk of local stress concentration, effectively avoiding damage to the wire, and significantly extending the service life of the wire.
In terms of grip performance, helical-formed suspension clamp is also very good. In some transmission lines in strong wind areas, when encountering windy weather, the wires will be subjected to huge tension. The grip of traditional wire clamps is limited. In this case, the wires can easily slip off the wire clamps, causing line failures. However, the helical-formed suspension clamp has a strong grip and can firmly grasp the wires, even in bad weather conditions, it can make the wires hang stably, effectively ensuring the safe operation of the power line.
In addition, the installation process of helical-formed suspension clamp is also very simple. Traditional metal fittings usually require the use of a variety of complex tools when installing, the installation steps are cumbersome, time-consuming, and the technical level of the installation workers is high. During the installation of helical-formed suspension clamp, workers only need to wrap each preformed wire in a predetermined direction without any auxiliary tools. This not only reduces the difficulty of installation, but also reduces the load on the installation workers to climb the tower. At the same time, it is also convenient to determine the installation quality through visual inspection.
In practical applications, helical-formed suspension clamp has played an important role in many fields. In the construction of urban power grids, fixtures can adapt to complex environments, allowing wires to be hung neatly and stably, and improving the aesthetics and safety of urban power grids. In mountainous areas and other areas with complex terrain, facing large height differences and large gear distances, helical-formed suspension clamp relies on strong adaptability to effectively solve the problem of wire suspension and ensure the stable transmission of electricity.
