[en] We report on the temperature (20-300 K) dependence of the resistivity, thermopower and thermal conductivity measurements of HgBaCaCuO(1223) polycrystalline superconductors with nominal composition Hg1.4Ba2Ca2CU3O8+delta. We present some discussion of the precision and the originality of the measurement methods which are especially used to measure the electrical resistivity and simultaneously the thermopower and the thermal conductivity as a function of temperature. The superconductivity fluctuation contributions to the transport properties of the materials are calculated and compared. The results are related to the 2D anisotropy of the crystallographic structure.
