The article addressed the following issues: general principles of superconductivity conditions in braking pairs; E. Schrodinger equation and F. Bloch law; superconductivity of 1st and 2nd kind in braking pairs; and discussion of results. The first group includes so-called superconductors of 1st kind, cooling with surface positive energy (Еп > 0). The negative sign of surface energy (Еп < 0) characterizes the superconductors of the second group. The top layers of the working surface are induced by the action of friction forces (FTi) and pulsed regular forces (Ni), between which the Eq. (0,35 – 0,6) Ni = FTi; is correct; in this case, they interact with the crystal lattice. The lower layers, located on the non-operational side of the surface, experience the internal interaction between the paired Cooper electrons and the crystal lattice. Electrical, magnetic, and thermal gradients decrease magnitude from external to internal exposure. The presence of various types of contacts and their transformation associated with electrical resistance promotes superconductivity of the local character of 1st kind. A characteristic feature of electric current is the appearance of a vortex magnetic field.
