Abstract
Provided is a polymer composition usable as a covering material of a power cable for outdoors, and more particularly, a non-crosslinked polyethylene composition for a power cable using a non-crosslinked type polyethylene resin instead of using a crosslinked polyethylene which is widely used around the world as the existing power cable insulator. The power cable using a covering material made of the polymer composition according to the present disclosure may have excellent tracking resistance to be appropriately used in costal areas containing large salts, industrial complexes containing large pollutants, and the like.
Claims10
A non-crosslinked polyethylene composition for a power cable comprising:
- based on 100 parts by weight of a base resin containing a middle-density polyethylene resin and a linear low-density polyethylene resin,
- 3 to 10 parts by weight of a metal hydroxide;
- 0.5 to 5 parts by weight of a red phosphorus;
- and
- 1 to 5 parts by weight of carbon black,
- wherein the base resin is prepared by mixing 50 to 90 wt % of the middle-density polyethylene resin and 10 to 50 wt % of the linear low density polyethylene resin.
