Importance of poles in critical load combinations

The poles are generally designed for the following critical load combinations  :

(a)  Bending due to wind load on the cable and on  the exposed  faces,

(b)  Combined bending and torsion due to eccentric snapping of wires,

(c)  Maximum torsion due to skew snapping of wires,

(d)  Bending due to failure of all the wires on one side of pole, and

(e)  Handling and erection stresses in the poles.
