Structure facility, the structural behaviour of shaft tower directly influence the security, economy and reliability of variety classes circuit.From the material of shaft tower
From the point of view of matter development, the shaft tower applied both at home and abroad in overhead transmission line mainly has wooden shaft tower, concrete shaft tower or prestressing force
Concrete shaft tower, concrete filled steel tube shaft tower, all-metal material shaft tower (steel pipe tower or steel tower etc.) several classes.
Wherein wooden shaft tower is mainly used in area of the forest reserves such as Canada and the U.S. compared with horn of plenty, concrete or pre-
Prestressed concrete shaft tower is mainly used in the more poor area of the forest reserves such as South America, Europe, Africa, Asia or development
Country.For China, wooden shaft tower is not used substantially, was once largely used on 35-110V circuits before concrete shaft tower,
