[0002] The main component of the steel pipe tower is a multi-rib steel pipe pole, and other components are formed by a lattice tower composed of steel pipes or sectional steels. The steel pipe tower is a support structure for supporting conductor wires and lightning wires of an overhead transmission line. The steel pipe tower can satisfy the distance limit requirement of the conductor wires to the ground and objects, and can bear the load of the conductor wires, lightning wires and itself and external load. The multi-rib steel pipe pole has a large bottom and a small top and has a multi-rib prism shape.
