How To Distinguish Silicone Fusing Tape Insulation Level
How to distinguish silicone rubber self fusing tape insulation level
In the insulation performance, because of different requirements and different levels can be divided into: Y, A, E, B, F, H
For people who are not technical or engineering staff, it is often difficult to figure out what they are different. Here's a brief introduction:
Motor insulation level refers to the heat resistance of the insulation materials used, points A, E, B, F, H level. Permissible temperature rise is the limit at which the temperature of the motor increases compared to the ambient temperature.
Insulation temperature class A class E class B class F class H class
The 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 electrical and electronic equipment, insulation is the weakest link. Insulating materials are especially susceptible to high temperatures and accelerate aging and damage. Different insulating materials have different heat resistance, using different insulating materials, electrical equipment, its ability to withstand high temperatures are different. Therefore, the general electrical equipment are provided for the maximum temperature of their work.
People according to the ability of different insulating materials to withstand high temperatures to its provisions of the maximum allowable temperature of 7, according to the size of the temperature were arranged: Y, A, E, B, F, H and C. Their allowable working temperature is: 90,105,120,130,155,180 and above 180 ℃.
