Corona ring coil can evenly disperse the locally concentrated electric field intensity to the surface of the ring, control the electric field gradient below the air breakdown field strength, and suppress the generation of corona discharge from the source.

In the ADSS optical cable erection system, helical suspension clamp for ADSS​ and ADSS dead end tension clamp are two accessories that complement each other but are very easy to be confused. For buyers, clearly distinguishing their positioning, functions and applicable scenarios can not only avoid engineering hidden dangers, but also realize the stable operation of the entire life cycle of optical cables and control comprehensive costs.

As an important component to ensure the safety of line connections in the power field, the cable joint box's operation stability will directly affect the reliability of the entire power system.

From the principle point of view, corona discharge is a partial discharge phenomenon caused by the ionization of air under a high-voltage electric field. It is commonly found on the tip or irregular surface of high-voltage power transmission and transformation equipment, power capacitors, transformers and other equipment.

According to statistics from the International Energy Agency, the annual maintenance cost of power equipment caused by wire vibration exceeds 3 billion U.S. dollars, and the loss of power outages caused by failures is even more difficult to calculate. At this time, the effect of spiral vibration damper​ appeared. Spiral vibration damper is not a simple buffer device, but through specific structural design and material characteristics, it actively cancels the vibration energy of the wire and cuts off the hidden dangers of failure from the source.

The working principle of ADSS dead end tension clamp​ is to accurately accept and scientifically transmit the tension of the optical cable. After the tension anchoring is completed, the second task of the ADSS dead end tension clamp is to disperse the concentrated stress and protect the optical cable body. At the same time, ADSS dead end tension clamp also needs to continue to deal with the erosion of the complex outdoor environment.
