INSULATION MATERIAL COMPOSITION FOR DC POWER CABLE AND THE DC POWER CABLE USING THE SAME

摘要

Provided is an insulation material composition for a DC power cable, comprising 0.5 to 5 parts by weight of surface-modified nano-sized cubic magnesium oxide, per 100 parts by weight of a crosslinked low-density polyethylene base resin. A DC power cable with an insulation made from the insulation material composition of the present invention has an increased volume resistivity and an excellent space charge suppression effect.
