Abstract :
XLPE was impregnated with 4 kinds of dielectric liquids to fill up large (>several 10 nm) free volume. This treatment removes space for electrons to be accelerated to high energy. The experimental results show that liquid impregnation drastically increases ac tree resistance of XLPE, but it does not change impulse characteristics
