随着我国电力大规模长距离输送项目的实施,如“西电东送”、“全国农网改造”、三峡电站的建成和投入使用、以及城市化进程的加快,使得电力塔杆、灯杆的市场需求量与日俱增,一个新兴行业应运而生一电力塔杆、灯杆制造业(目前我国已达3000家左右)。用薄板轧制焊接的电力塔杆、灯杆由于制造成本低,美化效果好、安装方便,并可根据实际需要高度进行现场制作等显著优点,在电力输送、城镇电网改造和城市化建设工程中已逐渐取代高度不够、体积太大、造型不够美观的水泥电杆及一些电力输送铁塔,但在其制造过程中,合缝焊接仍是一大技术难题。目前国内大多数电力塔杆、
With the implementation of China’s large-scale long-distance power transmission projects, such as the “west to east”, “national grid transformation”, the completion and put into use of the Three Gorges Hydropower Station, and the acceleration of the urbanization process, making the power tower Market demand for poles and poles is increasing day by day. An emerging industry has emerged as a power tower and light pole manufacturing industry (at present, China has reached about 3,000). Thin-plate welded welded power poles, poles due to low manufacturing costs, beautification effect, ease of installation, and according to the actual needs of a high degree of on-site production and other significant advantages in power transmission, urban power grids and urbanization projects Has gradually replaced the height is not enough, the volume is too large, the shape is not beautiful enough cement poles and some power transmission tower, but in the manufacturing process, seam welding is still a major technical problems. At present, most of the power tower poles,
