500kV活性粉末混凝土电杆的设计

The pole design of 500 kV reactive powder concrete

500kV活性粉末混凝土电杆,利用了活性粉末混凝土的高强度,提高了混凝土电杆的强度和抗裂性能。介绍了现行电杆设计方法在500kV活性粉末混凝土电杆中的设计过程。这种电杆的抗冻性能好、耐腐蚀性高。能适应恶劣的大气环境,尤其适用北方寒冷地区,可在目前500kV超高压送电线路中使用,并发挥其显著的经济效应和社会效益。

Because 500 kV reactive powder concrete （ RPC ） pole makes full use of the high strength of RPC, the strength and anti-crack property of RPC wire pole is increased greatly. The design approach of RPC wire pole was introduced in detail with the existent wire pole design theory method in this paper. It is pointed out that the properties of anti -freezing and anti-rusting of this kind of wire pole are improved. So it can adapt bad atmosphere environment, especially in the cold region. It is predicted that the RPC wire pole can be utilized in high voltage transmission lines, and it can exert economical and social benefit.
