Description
The company came to wind power with over 60 years of experience in electrical equipment for industry and power systems. The generators are developed with new design methods, materials and manufacturing technologies, so they turn out compact and suit various power generation tasks. Together with them the manufacturer supplies converters, switchboards, cubicles, supervisory control systems, transformers, electric motors and industrial coatings for wind turbines.
Induction generators come with a single feed (SFIG) or a double feed (DFIG); synchronous ones have permanent magnets (PM) or electromagnetic excitation (EESG). Frequency is 50 or 60 Hz, insulation class F or H. Cooling is air-to-air, air-to-water or open ventilation; the manufacturer's overview catalog also mentions air, water and ODP with forced ventilation. In the manufacturer's own AGW 147/4.2 and AGW 172/7.0 wind turbine platforms, permanent-magnet synchronous generators connected through a full-scale converter are used.
The generators are built in series at the manufacturer's own production sites. The manufacturer itself makes winding copper wire, has an insulation laboratory where insulation materials and systems are studied and tested according to international standards, a frame fabrication shop (welding, cutting, forming) and machining of shafts, end shields and frames to an accuracy of thousandths of a millimeter. Stators, wound rotors and other assemblies with finished windings are fully immersed in an autoclave and impregnated using GVPI (global vacuum pressure impregnation) technology, so the insulation is uniform and repeatable from machine to machine. The manufacturer works to its own designs and to customer drawings (built to print).
The generators are tested according to NBR 17094-3, IEC 60034, NEMA MG 1 or API in one of the largest laboratories in Latin America, where the design characteristics are confirmed. The service department carries out diagnostics, commissioning and round-the-clock duty. Medium and large machines are repaired at the customer's site or at the plants in Jaraguá do Sul, Sertãozinho and São Bernardo do Campo using the same technology as for new ones. These plants are also approved for work on equipment for hazardous areas. For wind turbines the company performs electrical and mechanical repair, reverse engineering, upgrades, rewinding of stators and rotors, replacement of magnets and shafts, and metallization of shafts.
