Spiral vibration damper is a professional device used on overhead transmission lines to suppress the breeze vibration of wires. Under the action of a stable breeze, the wires of overhead transmission lines will produce periodic vibration perpendicular to the direction of the line, which is what we call breeze vibration. This seemingly slight vibration, if it persists for a long time, will cause metal fatigue of the wire, which will cause serious problems such as broken strands and disconnections, and pose a great threat to the safety and stability of power transmission. Through its unique structural design and physical principles, spiral vibration damper can effectively consume vibration energy and control the vibration amplitude of the wire within a safe range, thereby extending the service life of the wire and ensuring the reliable operation of the power system.

The two main reasons for grounding are to protect the safety of personnel and equipment and to ensure the stable operation of the electrical system. According to statistics from the International Electrical Safety Association, in industrial environments where there is no perfect grounding system, the incidence of electric shock accidents is more than 5 times that of standardized grounding scenarios. The grounding system can quickly introduce leakage current into the ground, reducing the potential of the equipment housing to a safe range.

​The use of suspension clamp for opgw cable needs to be strictly controlled from the early preparation stage. First of all, the construction team needs to conduct a comprehensive inspection of the erection line, accurately evaluate the force of the suspension point according to the type of tower, terrain conditions and meteorological environment, and choose a fixture that matches the specifications based on this.

The working principle of spiral vibration damper is based on the energy dissipation theory of mechanical vibration. When the wires of an overhead transmission line vibrate under external forces such as wind, the anti-vibration whip will move synchronously with the vibration of the wires.

The main purpose of electrical grounding is to ensure the safety of personnel. When electrical equipment fails, such as when the insulating layer is damaged and the charged part is exposed, the grounding system can quickly introduce the fault current into the ground.

In power transmission lines, tension-resistant wire clamps are important components that connect wires to poles and towers and bear the tension of wires. The performance of wire clamps will directly affect the safety of the line and the operation and maintenance cost. The tension-resistant wire clamps are divided into bolt type, compression type and preformed type. In this article, we will understand the specific differences between several wire clamps.
