VISIBLE CABLE AT NIGHT

PROBLEM TO BE SOLVED: To provide a cable which is used for a guide mark on a passageway in an emergency or a sign for corners of a road and which is visible at night and has a highly light-emitting brightness and a high strength by preparing the light-emitting material layer with a mixture of light-accumulating pigment or a fluorescent agent and a resin and coating a wire with the light-emitting material layer. SOLUTION: A stranded wire 3 is made by twisting a plurality of steel wires 2 and the external periphery of the stranded wire 3 is coated with a light- emitting material layer 4. In this case, after pellets made by kneading a kind of light-accumulating pigment or a fluorescent agent and a resin are applied on the outer periphery of the stranded wire 3, the light-emitting material layer 4 is solidified. The characteristic of this cable 1 used for the visibility at night varies with appropriate selection of a resin for molding pellets. The durability of the cable 1 is increased when selecting a weather-resistant resin for example. In this way, if the cable 1 is laid along corners of a road, the visibility of the road can be improved at night.
