Abstract: A charging cable is provided. The charging cable includes wires for supplying power, a wire for transferring a signal and a sheath, and exhibits substantially improved mechanical properties such as low-temperature flexibility and abrasion resistance, substantially improved chemical properties such as oil resistance and substantially improved electrical properties such as insulation resistance. Moreover, the charging cable has improved electrical, mechanical and chemical properties by improving insulation resistance, heat resistance and low-temperature flexibility of wires, as compared to conventional wires coated with polyvinylchloride (PVC).

Abstract: Provided is an irradiation-crosslinked ethylene propylene diene monomer (EPDM) composition containing: EPDM 30 to 80 phr (parts per hundred resin) free of a crosslinking agent, a polyolefin (PO) resin 10 to 50 phr, a silicone rubber 5 to 40 phr, a flame retardant 20 to 30 phr, a crosslinking accelerator 5 to 10 phr, a crosslinking assistant 1 to 5 phr, an antioxidant 5 to 15 phr, and a lubricant 0.25 to 5 phr. Provided is a cable produced by: providing the irradiation-crosslinked EPDM composition; first kneading the composition using a kneader; second kneading the first kneaded composition using a roll mill; extruding the second kneaded composition using an extruder, and then cutting the extruded composition to produce pellets as a raw material for the cable; forming a cable of a predetermined length by extruding the pellets using an extruder; and irradiation-crosslinking the formed cable using an electron beam accelerator.
