3241 semiconductor laminated glass cloth board referred to as 3241 semiconductor board, in general, can be used to make high-voltage motor slot wedges and gaskets in the slot, mainly play the role of anti-corona, when used with semiconductor paint matching. It is made of alkali-free glass fiber cloth soaked in epoxy resin by electricians, baked and hot pressed. The heat resistance class is F class, which has high mechanical and heat resistance properties.
