Problems solved by technology

[0002] The current geothermal cable electric heating technology, its laying method is mainly wet laying method buried under cement, the structure of geothermal cable is mainly based on heating wire, single-layer insulation, single-layer shielding + ground wire, and the construction method is mainly In order to lay the heat insulation layer, steel wire mesh, geothermal cable, over-temperature protection temperature sensor, cement mortar + ground decoration layer, the laying and construction process is complicated, and due to the large construction site, there are few over-temperature protection temperature measurement sensors. , can not play the role of over-temperature protection, and because the geothermal cable and over-temperature protection temperature sensor are not well sealed during the construction process, the failure rate is high. Once damaged, it will be irreparable and there is no replacement. In order to solve these problems, some manufacturers have launched In the current dry laying method, the geothermal cable still uses the same products as the wet laying method, and the laying method is too simple, but the cement layer is canceled, and the ground decoration layer can only be the floor, which is limited. This type of dry laying method cannot be used in the living room, bathroom, kitchen and other places where tiles need to be installed in the family
