What are the insulating function boards?
3241 semiconductor glass cloth board: It has anti-corona properties, and its surface resistance is 1.0*103-5 under normal conditions. It is used in the electronics industry.
3341F grade magnetic conductive glass cloth board: it has good heat resistance and magnetic permeability, magnetic permeability ≥ 7%, density 28 ~ 33 (generally should be above 3), temperature resistance 155 ℃, non-insulation purpose. It is used for magnetic slot wedges of motors and is the main material of energy-saving frequency conversion motors.
3351H grade magnetic glass cloth board: the performance is similar to 3341 board, but the temperature resistance grade is higher than 3341 (180°C).
