INSULATOR COMPOSITION FOR DC POWER CABLE CAPABLE OF IMPARTING EXCELLENT SPACE CHARGE REDUCTION EFFECT AND IMPROVED EXTRUSION PROPERTY, AND A POWER CABLE MANUFACTURED BY USING THE SAME
INSULATOR COMPOSITION FOR DC POWER CABLE CAPABLE OF IMPARTING EXCELLENT SPACE CHARGE REDUCTION EFFECT AND IMPROVED EXTRUSION PROPERTY, AND A POWER CABLE MANUFACTURED BY USING THE SAME
PURPOSE: An insulator composition for DC power cable is provided to restrain the generation of crosslinked side product, thereby capable of improving extrusion property because a crosslinking process is not required.;CONSTITUTION: An insulator composition for DC power cable comprises 0.5-5 parts by weight of nano inorganic nanoparticles based on 100.0 parts by weight of polypropylene base resin. The nano inorganic particle is one or more kinds selected from silicon oxide(SiO2), titanium oxide(TiO2), carbon black, graphite powder, and surface modified cubic type magnesium oxide. The polypropylene base resin is copolymerized of one or more monomers selected from C4-C8 alpha-olefins and ethylene.;COPYRIGHT KIPO 2012
