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

摘要

PURPOSE: An insulation composition for a direct current cable, and the cable using thereof are provided to offer the excellent direct current dielectric breakdown strength and the impulse strength to the cable. CONSTITUTION: An insulation composition for a direct current cable contains the following: 100 parts of low density polyethylene base resin by weight; 0.05-0.5 parts of nanocarbon particles by weight; 1-4 parts of dicumyl peroxide cross-linking agent; and 0.1-1 parts of antioxidant by weight. The nanocarbon particles contain a graphite layer with less than 6 layers, and have the average diameter less than 500nm.
