Insulation level is (), can be divided into ()-class
Insulation Class
Motor insulation class is its heat-resistant insulating material level, points A, E, B, F, H level. Allows motor temperature is the temperature rise compared with the ambient temperature limits.
Insulation temperature rating A Class B Class E Class F Class H Class
Maximum allowable temperature () 105 120 130 155 180
Winding temperature rise limit (K) 60 75 80 100 125
Performance reference temperature () 80 95 100 120 145
In the generator and other electrical equipment, the insulation material is the weakest link. Insulating materials are particularly vulnerable to the impact of high temperature accelerated aging and damage. Performance of different insulating materials are different, use of
Insulating material with electrical equipment of their ability to have different tolerance to high temperature. Therefore, all electrical equipment in general the maximum temperature of the provisions of its work.
People according to different high-temperature insulating materials to their ability to withstand the provisions of 7 to allow the maximum temperature, in accordance with the temperature, size of the arrangement were: Y, A, E, B, F, H and C. Their temperatures were allowed to work
: 90,105,120,130,155,180, and more than 180 . Therefore, B-class insulation shows that the heat insulation of the generator with temperature 130 . Users should ensure that the generator does not work so fat
Electrical insulation material over the temperature to ensure that generators work.
Insulation grade class B insulation material, mainly by mica, asbestos, glass laminated or impregnated by the organic gel made of.
