DURIGNIT 2000 insulation system The insulation consists mainly of plastic materials with a high thermal overload capacity and resistance to tracking. It also meets the requirements placed on motors that are operating in tropical conditions (humid and hot climate). Temperature class 155 (F) (overtemperature limit 105 K at a cooling medium temperature of 40 °C) is used for 1G.5/1 H.5 motors. The output must be reduced by 13% to 87% when the motors are used in accordance with temperature class 130 (B). Temperature cIass 180 (H) (overtemperature limit 125 K at a cooling medium temperature of 40...
