Effects of byproducts of dicumyl peroxide on space charge formation in polyethylene

摘要

Crosslinked polyethylene (XLPE) cables are widely used for ac transmission. However, for dc transmission, they are still under feasibility study due to severe concern about easy accumulation of space charge into them. It is considered that byproducts of a well used crosslinking agent (dicumyl peroxide) (DCP), generate space charge into insulated cables. Acetophenone, /spl alpha/-methylstyrene, and cumylalcohol are the byproducts, of DCP. There have been many investigations on the effect of acetophenone on the charge distribution in polyethylene (PE). In the present paper, effect of cumylalcohol. on the space charge formation in PE has been investigated. Furthermore, effects of all the byproducts of DCT, acetophenone, a-methylstyrene, and cumylalcohol, on the space charge formation in PE have been compared by referring to our former reports about acetophenone and /spl alpha/-methylstyrene on the space charge formation in PE.
