Abstract: Special requirements of wind turbine running environment on insulation system and materials were analyzed and polyester-imide solvent impregnated resin suited for the insulation system of wind turbines were studied. Tests of performance simulation of bars were carried out on wind turbine insulation posed of various impregnated resin and ic wires to examine the salt spray resistance,high/low temperature resistant moist heat alternating performance,dielectric dissipation factor and breakdown voltages, the is shown that the wind turbine insulation system consisted of solvent-free polyesterimide impregnating resin,mica tape with polyester and molten polyimide lappde ic wire has l
