The fluorescent luminous color separation band is arranged along an axis direction of the weather-resistance insulating layer and is extended to two ends of the weather-resistance insulating layer. According to the luminous overhead insulation cable of the utility model, the fluorescent luminous color separation band which is arranged along the axis direction of the insulating layer and is extended to the two ends of the insulating layer is arranged on an outer wall of the weather-resistance insulating layer. The fluorescent luminous color separation band can give out light in a dark or insufficient light environment so that a position of the cable can be displayed. People can visually see the position of the cable in a daily production life so that a cable line can be effectively avoided, the cable can be prevented from being damaged and the people can be prevented from being hurt by the damaged cable.
