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.

We use preformed armour rods for ACSR conductor in transmission lines, the main reason is that it can avoid the risk of wire damage from the root cause and build a line of defense for the safe operation of the line.

​The generation of corona stems from the fact that the electric field strength on the surface of the high-voltage conductor exceeds the critical value of air breakdown, resulting in the ionization of air molecules to form a partial discharge.

From the point of view of basic functions, the most important purpose of the cable connection box is to achieve a stable connection between cables and lossless transmission of signals.
