Diagrams circumferential stress circumferential deformation and critical voltage flexibility, necessary for computations conduction on radial durability, inflexibility and stability testing are obtained for windings with conductors of round cross-section taking into account deformations of the initial bend appearing at winding,. The analysis of the obtained results showed that because of plastic deformations of the initial bend radial durability of windings increases, radial inflexibility at small circumferential deformations decreases, at large deformations it increases, critical voltages of radial stability decrease.
