This article deals with the effect of orientation on the electrical properties (tangent of the angle of dielectric losses tan δ, electric strength E , and lifetime τ) of polymer films. It is shown that the orientational stretching of PVC and PC films leads to the change of the temperature position of dipole segmental losses and reduces the value of tan δ in the maximum of this region. Under the orientation the electric strength of PE and PVC films increases considerably, and the lifetime τ increases under the high strengths of the field, and reduces under the low ones. The mechanical loads causing no orientation only reduce the lifetime of the polymer films.
