Based on the stress performance of steel pole of transmission line, the steel pole is simplified as a matter of crossbending and torque with variable sections and complex loads.
On the analysis of the velocity and the stress distribution on the asymmetrical cross section ofa orifice, the cause of the bending deformity of a melt thread has been discussed.

The loading of a tubular busbar is equivalent to that of a large-span beam, and the stress on the cross -section is mainly the tensile stress of the dead weight bending moment with much deflection.
