The temperature widths of the resistive transition as well as the thermal fluctuations of bulk (Bi_{0.6}Pb_{0.4})_2Sr_2Ca_2Cu_{3}O_{x} superconductor with T_{c,50%} = 107.1 K were studied. The applied magnetic field widens the resistive transition according to the following formula: ΔT = CH^{m} + ΔT_{0}. The value of exponent m = 0.44 suggests that there is strong pining of vortices, especially at lower temperatures. The critical exponents λ of the conductivity were calculated using the following equation: Δσ = Kε^{-λ}, with the λ_1 = 1.75 close to the zero critical temperature and λ_2 = 3.77 at higher temperatures. These values were discussed within the available theoretical models.
