The electrical insulation system for wires used in generators, electric motors, transformers, and other wire-wound electrical components is divided into different classes by temperature and temperature rise. The electrical insulation system is sometimes referred to as insulation class or thermal classification. The different classes are defined by NEMA, Underwriters Laboratories (UL), and IEC standards. WebLe classi di isolamento elettrico sono il raggruppamento omogeneo definito dall'IEC (International Electrotechnical Commission) delle caratteristiche tecniche applicabili …
WebWind Class Class 1 turbines are designed to cope with the tough operating conditions experienced at sites with average wind speeds above 8.5 m/s. Typically these turbines have smaller rotors (i.e. shorter blades) and are on shorter towers to minimise structural loads. They are also heavier-duty in design, which makes them more expensive.
