​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.
