The present invention relates to a communication cable composition, and a wire and a cable coated with same, the communication cable composition comprising 01-5 parts by weight of an antioxidant and 01-5 parts by weight of a lubricant with respect to 100 parts by weight of at least one polypropylene resin selected from among a thermoplastic olefin, a polypropylene block copolymer, and a polypropylene homopolymer. In the present invention, it is possible to produce a communication cable resin composition having excellent communication performance, heat resistance, oil resistance, and chemical resistance by using a base resin and an antioxidant, wherein various polypropylene resins are used alone or, as appropriate, in combinations as the base resin. An insulated wire and a communication cable coated with such a composition have the risk of being exposed to oil and various chemicals when used in industrial sites and automobiles and the like, and thus the stability of the cable can be further improved by increasing chemical resistance and oil resistance. In addition, the insulated wire and the communication cable increase heat resistance to the UL 105°C level when used in electronic/electrical appliances, home appliances, automobiles, etc., and thus can be used even in places requiring high heat resistance, and has the effect of reducing restrictions on installation sites as compared to existing wires and cables by achieving high heat resistance.
