Description

An energy-saving structural steel pipe pole

technical field

The utility model relates to the technical field of power transmission, in particular to a steel pipe pole.

Background technique

In the current power transmission, the steel pipe pole is almost a kind of structural support tower that must be used. Because the steel pipe pole has the advantages of fast construction, safety and reliability, it has been widely used in the field of high voltage transmission. However, the current steel pipe poles are mostly multi-edged and multi-section, and the cross arm is connected to the main structure by bolts. The current design has the following disadvantages: there is no reinforcing rib in the steel pipe pole. In order to achieve the strength, rigidity and structural stability of the structure, it has to use Steel pipe rods with thicker walls have higher material costs.
