A non-halogenated flame-retarded covered wire is provided which includes a conductor and an insulating cover layer consisting of a first layer directly put into contact with the conductor and a second layer arranged outside the first layer, wherein the first layer is made of a flame-retarded polyolefin composition with Shore D hardness of under 60 and Oxygen Index of 24% and over, the second layer is made of a polyolefin composition with Shore D hardness of 60 and over, and thicknesses of the first and second layers are 30 mu m and over and between 65 mu m and 150 mu m, respectively. Thus, a non-halogenated flame-retarded covered wire, which is lightweight and is capable of diameter-reducing and wherein all of abrasion resistance, flame retardance, oil resistance, and bending resistance can be satisfied as a thin layer covered wire for motor vehicle use, can be realized. <IMAGE> |
