1. An electric cable, including:
- a conductor being made of wires a diameter of each of which is from 0.15 to 0.5 mm and having a cross-sectional area of 20 mm2 or more; and
an insulating resin including a flame retardant and covering an outer periphery of the conductor,wherein the insulating resin includes one or more resins selected from a group consisting of an ethylene-ethyl acrylate copolymer (EEA), an ethylene-vinyl acetate copolymer (EVA), an ethylene-methyl acrylate copolymer (EMA), and an EP rubber,wherein a ratio of a diameter of the electric cable to a diameter of the conductor is from 1.15 to 1.40, andwherein the insulating resin is cross-linked, and has a secant modulus of 10 to 50 MPa.

Abstract
An electric cable for improving flexibility of an insulating resin portion of the electric cable expressed by a secant modulus value is provided. In an electric cable 10a in which an outer periphery of a conductor 11 made of wires with diameters from 0.15 to 0.5 mm and having a cross-sectional area of 20 mm2 or more is covered with an insulating resin 12 including a flame retardant, a ratio of an electric cable diameter to a conductor diameter is from 1.15 to 1.40, and a secant modulus of the insulating resin 12 is from 10 to 50 MPa.

4. An electric cable, including:
-
a conductor having a cross-sectional area of 20 mm2 or more; and an inside insulating resin including a flame retardant and covering the conductor; a shielding conductor covering an outer periphery of the inside insulating resin; and an outside insulating resin covering an outer periphery of the shielding conductor, wherein each of the inside insulatin resin and the outside insulatin resin includes one or more resins selected from the group consisting ethylene-ethyl acrylate copolymer (EEA), an ethylene-vinyl acetate copolymer (EVA), an ethylene-methyl acrylate copolymer (EMA), and an EP rubber, wherein a ratio of a diameter of the electric cable to a diameter of the conductor is from 1.40 to 1.77, and wherein at least one of the inside insulating resin and the outside insulatin resin is cross-linked, and has a secant modulus of 10 to 50 MPa. - View Dependent Claims (5)
