[en] A new variant of nonlinear electrodynamics has been developed. The account of the effect of electromagnetic field spin on the space-time continuum is its characteristic feature. The appearance of non-linear members in equations of the theory breakes its calibration invariance, which may be interpreted as the appearance of the own sources of electromagnetic field. Studied is a series of strict electrostatic solutions with field functions non-singular in the whole space with the Coulomb asymptotics at infinity, the energy of non-linear electromagnetic field being finite for a wide enough spectrum of seeding masses. Strict three-dimensional solutions describing solitary waves-solutions are built up
