Background
With the continuous development of the technology, the awareness of traffic safety is stronger. Especially in present public transportation safety.
In recent years, in order to solve the windage yaw clearance problem of a suspension insulator string (including a jumper string), people often adopt methods such as installing a heavy hammer additionally or adopting a V-shaped string (or an L-shaped string) as shown in fig. 1, and the like, because windage flashover tripping accidents of a transmission line tower occur frequently.
For the method of adding the heavy hammer to restrain the windage yaw, the hanging string has limited number of the heavy hammers allowed to be added, so the effect of improving the windage yaw clearance is limited. Although the method adopting the V-shaped strings (or the L-shaped strings) can effectively inhibit windage yaw, the length of the cross arm is undoubtedly lengthened, and the tower load is increased.
