The effects of crosslinking byproducts on the electrical properties of low density polyethylene

, 2011
Crosslinked polyethylene (XLPE) is widely used for high voltage insulation in power transmission systems. However, it has been found that, after crosslinking with Dicumyl Peroxide (DCP), the crosslinking byproducts such as acetophenone, ?-methylstyrene ...
