环形混凝土被广泛应用在电力行业、通讯领域以及接触网架空线路中，具有诸多优势，比如电杆具有耐久性、维护简单、钢材成本低等，其发挥作用只需通过预制构件即可。但与一般水泥预制构件工业产品不同，将其运用到架空输电线路上为电杆，不仅与人们的生命、安全存在较大关系，还能发挥其较为重要的作用。电杆主要是在 混凝土硬化之前对钢筋施加张拉力，待到混凝土硬化后期，利用粘接力将其与钢筋锚固，以使钢筋回缩，促进混 凝土预应力的形成。电杆受荷载因素的影响，其存在的预压应力将全部抵消混凝土受拉期间的拉应力，在该情况 下，不仅不会产生横向裂缝，还能改变普通钢筋混凝土电杆的缺点。
Ring concrete is widely used in the electric power industry, communication field and overhead lines of overhead contact system, which has many advantages, such as the durability of the pole, simple maintenance, low cost of steel, and its role can only be achieved through prefabricated components. However, it is different from the ordinary industrial products of cement prefabricated components. It is not only related to people's life and safety, but also plays an important role when it is applied to overhead transmission lines as poles. The pole mainly applies tension to the reinforcement before the concrete hardens. When the concrete hardens in the later stage, it is anchored with the steel bar by the adhesive force, so as to make the reinforcement retract and promote the formation of concrete prestress. Under the influence of load factors, the pre compression stress of the pole will completely offset the tensile stress during the concrete tension. In this case, it will not produce transverse cracks, but also change the shortcomings of ordinary reinforced concrete poles.
