The present invention provides a rotor coupling having insulated structure which can assuredly prevent galvanic corrosion of bearing members, rotors and the like which is cause by shaft voltage, in a shaft system that requires insulation in which a generator is disposed in between a steam turbine and a gas turbine or a rotating machinery such as another steam turbine. The rotor coupling having insulated structure of the present invention is employed in power generating equipment in which a generator is disposed in between a steam turbine and a gas turbine or a rotating machinery such as another steam turbine, a generator rotor and a rotating machinery rotor are connected, a first grounding electrode is provided to the steam turbine rotor, and a second grounding electrode is provided to the generator rotor, wherein both the rotors between the generator and the steam turbine are connected in an electrically insulated state.
