Abstract
The invention provides a safe geothermal heating cable. A first conductor serves as a heating conductor, a second conductor serves as a circuit wire, the first conductor and the second conductor respectively comprise an inflaming retarding layer, and therefore heating of an inner layer is well controlled. In addition, an inflaming retarding layer is further arranged outside an insulation shielding layer wrapped around the first conductor and the second conductor, so that heat transferred from the inner layer is controlled. A heat preservation layer is further arranged to preserve the heat; as a temperature-resistant protection layer is arranged, the performance of the cable is guaranteed when the cable is unused or just starts to be used at a very low temperature. Because the insulation shielding layer is of an aluminum-plastic composite tape longitudinally wrapped structure, electromagnetism can be well shielded, and watertightness can be well achieved. A heating wire is of a three heating cable core bunch strand structure, so that it is ensured that a dual-layer extruded insulation layer will not be damaged during thermal expansion and cold contraction of a cable core, the cable is softer, and the heat dissipation rate is high. The safe geothermal heating cable is simple in structure, good in safety, excellent in heating performance and suitable for geothermal heating.
