The effects of such constituents as the crosslinked part, non-crosslinked LDPE part, antioxidant, and residual byproducts on the formation of space charge in XLPE have been investigated. It has been found that homocharge is developed in the pure crosslinked part of XLPE. The non-crosslinked LDPE part encourages the formation of heterocharge, although its influence is not strong. Residual byproducts generated during the crosslinking reaction encourage the formation of heterocharge, whereas antioxidant was found to prohibit the formation of heterocharge. Of these, residual byproducts have been found to impose the most pronounced influence on the formation of heterocharge in XLPE, so that only heterocharge is found in an as-pressed XLPE with semiconductive electrodes.
