Heat dissipation, flame-retardant and anti-breaking type power cable

The invention discloses a heat dissipation, flame-retardant and anti-breaking power cable, comprising a core wire and a protective layer, the inner ring of the protective layer is successively provided with an outer steel tape armor layer and an outer shielding layer inwards; the cavity formed between the outer shielding layer and the outer ring of the core wire is filled with a wire core fillingstrip, and a heat dissipation hole of the filling strip is arranged in the wire core filling strip made of thermal conductive silicone; the core wire comprises a conductor bundle, an insulating layer,an inner shielding layer, an inner steel tape armor layer and a flame-retardant layer, the heat dissipation and cooling effect of the invention is good, the temperature rise of the cable can be effectively controlled, the cable can be effectively operated for a long time, and the insulating layer is effectively prevented from bursting into flames by setting the fire retardant layer to ensure thepersonal safety; the steel tape armor layer is respectively arranged on the outside of the protective layer and the core wire, which greatly enhances the strength of the cable itself, thereby ensuringnormal power supply.
