    • The present invention relates to a semiconductive composition and a power cable using the same. The semiconductive composition according to the present invention constituting a semi-conductive layer of a power cable includes 100 parts by weight of a base resin composed of an ethylene-based copolymer resin; 45 to 70 parts by weight of a carbon black; and 0.2 to 5.0 parts by weight of a nonionic surfactant. The semiconductive composition according to the present invention has an improved interfacial smoothness in the semiconductive layer and the insulation layer of the power cable and an increased dielectric breakdown strength of the insulation layer. Also, the semiconductive composition according to the present invention may be useful to ensure an easy cleaning property of a mold upon extruding/molding a power cable.

    • Disclosed is a composition for producing a halogen-free flame-retardant insulating material using nano-technology. The present invention provides a composition for producing a halogen-free flame-retardant insulating material using nano-technology, including metal hydroxide treated with nanoboric acid; nano clay which is a compatibility enhancer of a base resin; a metal compound which is a flame-retardant formulation; and an antioxidant, based on the total weight of the polyolefin resin. The composition of the present invention has advantages that, if it is used for the flame-retardant insulating material, especially the insulating coating layer for wire, it maintains the equivalent physical properties such as the tensile strength or the elongation against the mechanical strength in comparison to the conventional products, and also is more environment-friendly than the conventional halogen-containing products, and also ensures the flame retardancy suitable for the standard of the grade VW-I of High Flame Retardance.
