Abstract :
Previous reports have shown that the addition of small amounts of acetophenone, cumyl alcohol, alpha methyl styrene, and cumene to devolatilized compression-molded samples of XLPE (cross-linked polyethylene) has a small effect on the breakdown strength of these samples. The AC breakdown strength is increased; the impulse breakdown strength is decreased. The question addressed is whether the results for the extruded XLPE cable insulation will be the same. The results presented suggest that, qualitatively, the results for the two types of XLPE are much the same. Quantitatively, the breakdown strength of the XLPE cable insulation is much less than that of the compression-molded XLPE
