DC power cable and cross-linked polyethylene composition

摘要

PPROBLEM TO BE SOLVED: To suppress aggregation of an inorganic filler for improving DC characteristics in an insulating layer of a cross-linked polyethylene (XLPE) cable, and to improve long extrusion characteristics of the XLPE-based cable. PSOLUTION: The cross-linked polyethylene composition includes the inorganic filler for improving the DC characteristics added thereto, and is used for the insulating layer of a DC power cable. In the cross-linked polyethylene composition, 0.01-0.5 wt.% of an amide-based lubricant or urea-based lubricant is contained. PCOPYRIGHT: (C)2010,JPO&INPIT
