Insulation Class
Motor insulation is heat-resistant insulating material for their grade, points A, E, B, F, H grade. Allows motor temperature is the temperature rise compared with the ambient temperature limit.
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. Insulation materials are particularly vulnerable to the effects of high temperature accelerated aging and damage. Performance of different insulating materials are different, with different insulation materials of electrical equipment of its ability to withstand high temperatures have different
. Therefore, all electrical equipment in general the maximum temperature of the provisions of its work.
People according to different insulation materials to their ability to withstand high temperatures provides 7 to allow the maximum temperature, were arranged according to the temperature size: Y, A, E, B, F, H and C. Their operating temperature are: 90,105,120,130,155,180, and more than 180 ℃. Because
ISO 3419 non-alloy steel and alloy steel butt welding pipe fittings
ISO 5251 stainless steel welded pipe fittings
ASME B16.9 Butt-welding pipe fittings forged steel manufacturing plant
ASME B16.11 socket welding and threaded forged steel pipe fittings
ASME B16.28 Forged Steel butt small radius elbows and returns
MSS SP-43 Forged stainless steel welded pipe fittings
MSS SP-75 wrought steel butt welding pipe fittings
MSS SP-79 socket welding reducer inserts
This, B-class insulation shows that the thermal insulation of the generator with temperature 130 ℃. Users should ensure that the generator does not work to make generators more than the temperature of insulating material to ensure that generators work.
Insulation class B class insulation material, primarily from the mica, asbestos, glass impregnated by the organic or made of plastic glue.
pipe fittings and stainless steel pipe fittings they have one thing in common, it is metal. But they are different, so they have a different value. If you want to know more, you can visit http://www.hlpipefittings.com zll10417002
