Abstract	The impulse breakdown mechanism of PPLP (polypropylene laminated paper) is investigated in detail, taking into consideration the effect of PP (polypropylene) film. It is found that, although both positive and negative streamers affect the impulse breakdown mechanism, each effect is very different. That is, the positive charges are trapped on the surface of PP film easily, while the negative charges tend to spread into the insulating material. Consequently, it is suggested that the most essential factor of the impulse breakdown mechanism is the positive charges. Comparison of a sheet of PPLP and a specimen made of Kraft papers and PP film suggests the importance of the effect of oil thin films between Kraft paper and PP film.<>
