Steel tie rod manufacturer customized steel tie rod

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 quality and soil pollution are becoming more and more serious, resulting in serious corrosion of more and more tower grounding downleads and stay rods, which can not reach the effective service life, resulting in the inability to guarantee the grounding resistance, the increase of lightning trip rate and the decline of stay rod stability, which seriously threatens the safe operation of the line.

Introduction: with the rapid development of power industry, the use of transmission line poles and towers is increasing day by day. However, due to the area of 536 square kilometers of water area and various wetlands in Jiangnan, accounting for 11% of the land area of the city, there are also a large area of paddy fields. Many transmission line towers are located in paddy fields or wetlands, and the water quality and soil pollution are becoming more and more serious, resulting in serious corrosion of more and more tower grounding downleads and stay rods, which can not reach the effective service life, resulting in the inability to guarantee the grounding resistance, the increase of lightning trip rate and the decline of stay rod stability, which seriously threatens the safe operation of the line. At the same time, with the increasing difficulty of policy treatment, the maintenance cost of the line is huge every year. Through the analysis, it is found that the best way to solve a series of problems such as seedling compensation cost and labor cost caused by subsequent daily maintenance and repair is to take corresponding protective measures in the construction stage.
