Temperature grade of 4 ft long 3 4 inch diameter epoxy glass laminate G10 FR4

The insulation performance of 4 ft long 3 4 inch diameter epoxy glass laminate G10 FR4 used in the electronics industry is always concerned. In fact, in most materials, the insulation performance is related to the temperature resistance of the materials. The better the temperature resistance of 4 ft long 3 4 inch diameter epoxy glass laminate G10 FR4 is, the better the insulation performance will be. The reverse is worse. When choosing electrical insulation materials, a lot of enterprises or customers will pay attention to the insulation strength value. Processing materials in a reasonable range, the finished product can be guaranteed.

Each type of 4 ft long 3 4 inch diameter epoxy glass laminate G10 FR4 has an appropriate allowable working temperature, which requires us to control an appropriate temperature when using the insulating rubber plate. This is also a good way to maintain the rubber plate, because the insulation performance of the rubber plate is not good at high temperature, but also the rubber plate will rapidly age.

Relationship between 4 ft long 3 4 inch diameter epoxy glass laminate G10 FR4 temperature and insulation temperature grade: Insulation materials are classified into grade Y, A, E, B, F, H, C, etc. according to heat resistance. For example, the rated working temperature of grade A insulation is 105℃. Most of the insulation materials used in distribution transformers and electric motors belong to grade A, such as epoxy resin insulation board, etc.

Insulation temperature class: A, E, B, F, H

Rated temperature (℃): 105 120 130 155 180

Winding temperature rise limit (K): 60 75 80 100 125

Performance reference temperature (℃): 80 95 100 120 145c
