Company http://vecgroup.ru/about/partners/marelli-motori/">Marelli Motori has developed a wide range of models marine alternators a variety of designs and a wide range of power values up to 11,000 kVA covering low, medium and high levels. These are high-quality, safe, efficient and well-prepared working units for the conditions of the sea.
The device body is made of a rigid steel frame and shields made of high-strength cast iron with spherical graphite or gray cast iron, and structural steel is also used. The shaft material is laminated carbon steel, forged and with a diameter of 290 mm and above. 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). It is installed horizontally, IM 1001 or IM 1101 in accordance with IEC 60034-7.
