Company Marelli Motori She has developed a wide range of models of AC hydro generators of various designs and a wide range of power values up to 9,500 kVA covering low, medium and high levels. An excellent solution for hydroelectric power plants, they are installed on any type of turbine (bucket, radial-axial, rotary-blade, Turgo, cross-flow).
Generator design MJHT It is enclosed in a rigid frame made of durable steel and additional stiffeners for even greater strength. Cast iron body (grey and with spherical graphite), forged shaft made of laminated carbon steel, diameter from 290 mm and above, design on request. The stator/rotor windings are coated with unsaturated polyester and polyamide resins, insulation class – H (synthetic enamel). Protection against radio interference of class B (EN 55011). Installation in horizontal and vertical positions, individual offers on request.
