Electric angle steel tower
Power tower is a kind of steel structure frame which keeps a certain safe distance between the supporting conductors, the ground wire and the ground buildings in the transmission line. From the structure: general angle steel tower, steel pipe pole and steel tube narrow base tower. The angle steel tower is generally used in the field, and the steel pipe pole and steel pipe narrow base tower are generally used in the urban area because the floor area is smaller than the angle steel tower.
Electric angle steel tower is a kind of steel structure which can keep a certain safe distance between the supporting conductors and the ground buildings in the transmission line. According to its shape, it can be generally divided into five types: wine cup type power tower, cat head type power tower, up type power tower, dry type and bucket type. According to the purpose, it can be divided into tension type power tower, straight line type power tower, angle type power tower and transposition type power tower The structural characteristics of tower (replacement of conductor phase position tower), terminal power tower and crossing power tower are that various tower types belong to space truss structure, and the members are mainly composed of single equilateral angle steel or combined angle steel. Q235 (A3F) and Q345 (16Mn) are generally used. The connection between members is made of rough bolts, and the whole tower is connected by angle steel and connecting steel Some parts such as tower foot are welded into an assembly by several steel plates. Therefore, it is very convenient for hot galvanizing, anticorrosion, transportation and erection. For the tower whose height is less than 60m, the foot nail shall be set on one of the main materials of the tower to facilitate the construction workers to climb the tower.
