The driving motors used in electric vehicles and industrial machines bear high voltageSurgetect®︎
The driving motors used in electric vehicles and industrial machines bear high voltage, and the protective insulating film is damaged by high-voltage partial discharge. SURGETECT ® The series uses nanotechnology to achieve high corona resistance and insulation characteristics, which will protect the machine. Because the nano-sized inorganic filler is evenly dispersed, the film remains transparent, and the reduced toughness brought by the inorganic filler is overcome.
As a base polyimide, surgetect (PI) has the highest level of heat resistance. Not only high heat resistance and toughness, but also effective protection and suppression of partial discharge according to low dielectric.
