Lightweight flame-retardant copper core polyvinyl chloride insulated wire

The utility model discloses a light flame-retardant copper core polyvinyl chloride insulated wire which comprises a copper core, a polyvinyl chloride insulating layer arranged outside the copper core, a low-voltage polyvinyl chloride heat absorption layer arranged outside the polyvinyl chloride insulating layer, heat dissipation aluminum foil strips wound outside the low-voltage polyvinyl chloride heat absorption layer, and heat conduction strips wound between the heat dissipation aluminum foil strips at intervals. A heat dissipation silica gel layer is wound on the outer wall of the heat dissipation aluminum foil strip, a flame-retardant viscose acetal fiber layer is arranged outside the heat dissipation silica gel layer, and an XLPE outer layer is arranged outside the flame-retardant viscose acetal fiber layer. The insulation structure and the heat conduction structure outside the copper core are optimized, so that the low-voltage polyvinyl chloride heat absorption layer conducts internal heat to the outer
