The masses of vector supermultiplet and of the Higgs supertriplet in standard supersymmetric SU(5) model are calculated. Taking into account uncertainties related with the initial coupling constants and threshold corrections we find that in supersymmetric SU(5) model the scale of the supersymmetry breaking could be up to 50 Tev. We find that in the extensions of the standard SU(5) supersymmetric model it is possible to increase the supersymmetry breaking scale up to O(10¹²) Gev. In standard supersymmetric SU(5) model it is possible to increase the GUT scale up to 5 · 10¹⁷ Gev provided that the masses of chiral superoctets and supertriplets are m₃,₈ O(10¹³) Gev. We also propose SU(5) supersymmetric model with 6 light superdoublets and superoctet with a mass O(10⁹) Gev.
