Abstract
Provided is a non-crosslinked polyethylene composition for a power cable in which crosslinked polyethylene widely used in the world as an existing insulator for a power cable is replaced with a non-crosslinked polyethylene resin, and more particularly, a non-crosslinked polyethylene composition for a power cable having excellent processability, AC dielectric breakdown strength, space charge distribution, and water tree resistance.
Claims8
