[0029] like Figures 1 to 3 As shown, a double-conductor energy storage heating cable includes a heating cable body 1, one end of the heating cable body 1 is connected with a cold line plug 2, and the other end is set by heat shrink sealing. The heating cable body 1 is equipped with a leakage protector 16 and a thermostat 3. The heating cable body 1 includes:

[0030] A sheath layer 4, the inner surface of which is wrapped with a braided layer 5;

[0031] A shielding layer 6, the outer surface of which is arranged on the inner surface of the braided layer 5;

[0032] An energy storage layer 7 is arranged inside the shielding layer 6;

[0033] The conductive wire is folded in half and arranged inside the energy storage layer 7 , and both ends of the conductive wire are connected to the cold wire plug 2 .

[0034] For example, by folding the wire in half to increase the thermal conductivity of the wire, and connecting the two ends of the wire to a cold line plug 2, not only is the installation convenient and quick, but the other end needs to be sealed, and there is no need to consider protection issues too much. By setting an energy storage layer 7 to reduce the heat loss efficiency, the heating efficiency of the heating cable is further improved. By setting a shielding layer 6, zero electromagnetic radiation is achieved. By setting a thermostat 3, the temperature state of the cable is monitored in real time. By setting a leakage protector 16, the entire line is protected.

[0035] As an optional embodiment, the sheath layer 4 is made of PVC material with a thickness of 0.80-1.0 mm.

[0036] As an optional embodiment, the braided layer 5 is woven from tinned copper wires, and the diameter of the tinned copper wires is 0.14 mm.

[0037] As an optional embodiment, the shielding layer 6 is made of aluminum-plastic film material.

[0038] As an optional embodiment, a cavity 8 is provided between the outer surface and the inner surface of the energy storage layer 7, and a plurality of connecting blocks 9 are provided in the cavity 8. The outer surface and the inner surface of the energy storage layer 7 are fixedly connected by the connecting blocks 9. A cross support plate 10 is fixedly provided inside the energy storage layer 7. A heat preservation channel 11 is hollowly provided in the cross support plate 10. The heat preservation channel 11 is connected to the cavity 8. The two ends of the wire are arranged in two opposite angles of the cross support plate 10. A plurality of annular grooves 12 are provided on the outer wall of the energy storage layer 7. A heat conductive ring 13 is sleeved in each of the annular grooves 12. Each of the heat conductive rings 13 is coaxially arranged with the energy storage layer 7, and each of the heat conductive rings 13 tightens the wire through the annular groove 12 so that the wire is close to the cross support plate 10 for heat conduction.

[0039] For example, the cross support plate 10 is made of heat-conducting material, and the heat generated by the wire is absorbed by the cross support plate 10 into the insulation channel 11, and then passes through the insulation channel 11 to the cavity 8, so that the heat acts on the entire energy storage layer 7, and the heat is transferred to the other two opposite angles of the cross support plate 10 through the heat-conducting ring 13 to improve the heating efficiency of the heating cable.

[0040] As an optional embodiment, the wire includes a heat-generating conductor 14 and an insulating layer 15 wrapped around the outer surface of the heat-generating conductor 14 .
