Through adopting above-mentioned technical scheme, the fire-retardant layer that the enhancement layer outside set up is made by polymeric material, can be when melting ice and snow, prevent that the electric wire surface from being burnt and being out of shape, thereby the life of extension electric wire, the inside packing on heat insulation layer has the asbestos, heat-proof quality has, can prevent effectively that ambient temperature from producing the influence to the inside structure of electric wire, thereby guarantee the integrality of the inside structure of electric wire, make the life that can prolong the electric wire, the enhancement layer uses with the strengthening rib cooperation, can strengthen the intensity of electric wire self, thereby make the difficult fracture of electric wire, stainless steel mesh's outer wall is provided with the multiunit connecting rod, make can increase stainless steel mesh's fastness and stability.

The utility model is further provided that the inside of the heat insulation layer is filled with asbestos.

Through adopting above-mentioned technical scheme, have the heat-proof quality, can prevent effectively that ambient temperature from influencing the structure of electric wire inside to guarantee the integrality of the inside structure of electric wire, make the life that can prolong the electric wire.

The utility model is further provided that a plurality of groups of reinforcing ribs penetrate through the reinforcing layer.

Through adopting above-mentioned technical scheme, can strengthen the intensity of electric wire self to make the difficult fracture of electric wire.

The utility model is further provided that a plurality of groups of connecting rods are uniformly arranged on the outer side of the stainless steel wire mesh.

Through adopting above-mentioned technical scheme, can increase stainless steel net's fastness and stability.

In summary, the utility model mainly has the following beneficial effects: the utility model can prevent the surface of the electric wire from being burnt and deformed while melting ice and snow by arranging the flame-retardant layer, the heat insulation layer, the reinforcing ribs and the connecting rods, the flame-retardant layer arranged outside the reinforcing layer is made of a polymeric material, so that the service life of the electric wire is prolonged, the heat insulation layer is internally filled with asbestos, has heat insulation performance, and can effectively prevent the external temperature from influencing the internal structure of the electric wire, thereby ensuring the integrity of the internal structure of the electric wire and prolonging the service life of the electric wire, the reinforcing layer is matched with the reinforcing ribs for use, so that the strength of the electric wire can be enhanced, the electric wire is not easy to break, and the outer wall of the stainless steel wire net is provided with a plurality of groups of connecting rods, so that the firmness and the stability of the stainless steel wire net can be increased.
