Transport analysis for helical confinement systems are studied based on the electrostatic drift wave turbulence transport and the resistive interchange turbulence transport in addition to the neoclassical transport theory including the effect of radialelectric field and multi-helicity magnetic components. The thermal conductivities predicted by the above theories are compared with CHS (compact helical system) experimental data for NBI-heated plasmas. The experimental ion thermal conductivities in the central plasma region agree with the neoclassical value. And the electron thermal transport in the edge plasma region does not contradict the drift wave turbulence transport. For the plasma parameters in LHD (large helical device), 3-D equilibrium/1-D transport simulations including drift wave or empirical anomalous transport models are carried out, which suggests that the global confinement time of LHD is determined mainly by the electron anomalous transport near the plasma edge region rather than the helical ripple transport in the core region.
