Problems solved by technology

Since this kind of pole and tower structure is a metal structure, it is prone to corrosion, so the service life is short and the maintenance workload is heavy.
However, the mechanical strength of traditional ordinary concrete poles is not high, so it is difficult to apply to high-voltage power transmission lines, unless the cross-section is made relatively large, but this not only increases the self-weight, but also makes the construction very difficult. More importantly, it also increases cost

Description

technical field [0001] The invention belongs to the technical field of electric power materials, and in particular relates to an environment-friendly power transmission frame. Background technique [0002] The power transmission frame is a support used to support cables to transmit power, and is a common power material. The poles and towers widely used in overhead transmission lines at home and abroad mainly include wooden poles, concrete poles or prestressed concrete poles, steel pipe concrete poles, steel pipe poles and iron towers. Among them, the steel rod is firm and strong, but the cost is high and it is not corrosion-resistant. [0003] Concrete is a living building material. With the continuous development of concrete composition materials, people's understanding of material composite technology has been continuously improved. The performance requirements of concrete are not limited to compressive strength, but on the basis of strength, more attention is paid to t...
