What are the commonly used electrical insulation materials?

Common insulating materials for electrical insulating materials are: 3240 epoxy board, epoxy rod, epoxy tube, FR-4 board, SMC board, electric board, diphenyl ether board, silicone board, cold plate, PC board, PC endurance board, etc.

1. The insulating material is a material that is not electrically conductive under the allowable voltage, but it is not an absolutely non-conductive material. Under certain external electric field strength, conductive, polarization, loss, breakdown and other processes may occur, and long-term use will also occur. Aging occurs.

2. The electrical resistivity of the insulating material is very high, usually in the range of 1010 to 1022 Ω·m. In the motor, the insulation around the conductor separates the turns and isolates it from the grounded stator core to ensure safe operation of the motor.
