Angle Steel Diagonal Braces for Transmission Lines or Substations

Stay rod refers to the rod or other metal parts connecting the stay wire to the ground anchor. Many transmission line towers are located in paddy fields or wetlands, and the water and soil pollution is becoming increasingly serious, resulting in more and more tower grounding downlead and stay rods severely corroded and unable to achieve effective service life, which leads to the failure to ensure the grounding resistance, the increase of lightning trip rate, the decline of stay rod stability, and serious threats to the safe operation of the line. With the rapid development of the electric power industry, the use of transmission line poles and towers is increasing. However, the water area and various wetlands in Jiangnan are 536 square kilometers, accounting for 11% of the city's land area, and there are large areas of paddy fields. Many transmission line towers are located in paddy fields or wetlands, and the water and soil pollution is becoming increasingly serious, resulting in more and more tower grounding downlead and stay rods severely corroded and unable to achieve effective service life, which leads to the failure to ensure the grounding resistance, the increase of lightning trip rate, the decline of stay rod stability, and serious threats to the safe operation of the line. At the same time, with the increasing difficulty of policy processing, the maintenance cost of the line is huge every year. Through analysis, it is found that the best way to solve a series of problems such as young crops compensation cost and labor cost caused by subsequent daily maintenance and repair is to take corresponding protective measures in the construction stage.
