      As a key parameter of transmission conductor safety, the size of the conductor arc sag value is the key parameter that electricians pay attention to.

      As a key parameter of transmission conductor safety, the size of the conductor arc sag value is the key parameter that electricians pay attention to. When the conductor tension is large, the arc sag is relatively small, the conductor shows a more taut state; on the contrary, the tension decreases, the arc sag will increase, and the change of external load will break this delicate balance.




      Generally speaking, the conductor under the action of strong wind will be subjected to lateral force, and its force distribution will be changed, which may lead to the arc sag in the direction of the wind to appear offset or increase. In addition, the conductor ice cover in winter and early spring is more complicated, the weight of the ice will greatly increase the vertical load of the conductor, so that the arc sag increases sharply, and in serious cases, it may even lead to the conductor and the object below or the distance between neighboring wires is less than the safe distance, triggering short circuit, grounding and other faults. In addition, the temperature is another key factor affecting the arc sag, the conductor has the characteristics of thermal expansion and contraction, in the hot summer, high temperatures may make the conductor arc sag close to or even beyond the design limit; and in the cold winter, too low a temperature may lead to excessive contraction of the conductor, increasing the mechanical stress of the conductor, and causing damage to the tower and insulators and other related equipment.


      How does arc sag affect transmission line safety?

      Proper conductor arc sag is critical to the safe operation of transmission lines. Excessive arc sag, in addition to the electrical faults mentioned above, may also increase the risk of contact between the conductor and the ground, buildings, trees and other objects, jeopardizing the surrounding environment and personnel safety. At the same time, too large an arc sag will make the conductor in the breeze vibration and dance and other conditions of the amplitude increases, accelerating the conductor fatigue damage. But on the contrary, the arc sag is too small will also make the conductor to withstand too much tension, may lead to conductor strand breakage, wire breakage and even tower tilt.

      Guard the transmission string, transmission line wire arc sag online monitoring device new departure, DX-WPS100-HC DX-WPS100-HC is a powerful measurement and data monitoring device. ">Transmission Line Arc Sag Monitoring DeviceThe DX-WPS100-HC has powerful measurement and data acquisition capabilities, and with the laser sensing technology, it is able to directly measure the arc sag of the conductor or the distance to the ground, and at the same time, it supports the acquisition of a series of auxiliary measurements related to the arc sag of the conductor or the distance to the ground, such as conductor inclination, temperature, tension, and the distance to the ground. Inclination, temperature, tension and image. Through the built-in advanced algorithms, the device can process and analyze the collected data, so as to derive the state of the wire arc angle and distance to the ground, and through the computer, cell phone and other platforms real-time transmission to the staff, no matter where the staff are, can always view the real-time status of the line, to assist in the timely warning of potential hazards and disposal.



      Especially in the large spanning section, special geographic environment and complex working conditions, it is more necessary to strengthen the line conductor arc sag monitoring ability, so as to enhance the efficiency of the grid digital information management.
