摘　　要：在对低风压导线的机理进行简单阐述的同时,介绍了低风压导线的测试和发展过程。目前日本开发的低风压导线,在保持导线表面接近光滑圆周的基础上,通过设计不同表面沟槽的方式,降低导线的阻力系数。随着低风压导线设计的不断成熟,日本已经开发出了低风压低噪音的架空导线,以及具有良好抗积雪性能的绝缘输电线。对于低风压导线的测试,日本在风洞试验的基础上,通过实地线路的测试,验证了风洞试验数据的有效性。我国低风压导线的研究起步较晚,但发展较快,应用前景广阔。The thesis simply explains the mechanism of low-wind-pressure conductors, and expounds the development and test of the conductors. The drag coefficient of low-wind-pressure conductors which developed by Japanese re-searchers were reduced when grooves were made on the cylinder surface. As the design of low-wind-pressure conduc-tors gradually progressed, the Japanese companies have developed the conductor of low wind noise and low drag force, and the low wind-pressure insulated wire with excellent resistance against snow accretion. In the development process of low-wind-pressure conductors, conductors have undergone field verification test to demonstrate the characteristics based on the wind-tunnel test. China started late on the low-wind-pressure conductor, but it has developed fast. The low-wind-pressure conductor has broad prospects for application.
