Problems solved by technology

[0002] Traditional electric poles generally have the disadvantages of bulkiness, perishability, corrosion or cracking, and short service life. Construction, transportation, operation and maintenance are difficult, and various safety hazards are prone to occur. With the development of new material technology and its preparation process, composite materials have been obtained In order to achieve rapid development, composite poles have the advantages of light weight, corrosion resistance, high strength, and longer life. They are low in maintenance costs and can withstand extreme weather conditions. They can be used in projects such as power transmission and distribution lines, communication lines, and communication towers. Great replacement for traditional wooden poles, reinforced concrete poles and iron towers
At present, composite material poles have been applied in transmission towers. However, there are still many key problems in the processing technology of composite tapered poles that have not been resolved, which may result in higher production costs, or lead to the strength and stiffness of the produced tapered poles. performance is not enough
