Embodiment 1

[0021] Such as figure 1 As shown, a heating cable used for geothermal heating includes a heating body, and the heating body includes a cold wire 5 and a hot wire 4. The hot wire 4 is arranged below the ground surface, and its two ends are fixed with cold Line 5, its joint 6 is located below the ground surface, and its joint 6 is sleeved with a heat insulating sleeve 7 for waterproof sealing. The cold wire 5 leads out to the ground and is connected to a power switch; the heating body is covered with an insulating layer 3 , a shielding layer 2 and a protective sheath 1 in sequence. The heating wire 4 is made of chromium-nickel alloy wire, the insulating layer 3 is made of extruded cross-linked polyethylene, the shielding layer 2 is made of tinned copper wire and longitudinally wrapped aluminum skin, and the protective sheath 1 is Made of polyvinyl chloride material.

[0022] The heating cable of the present invention adopts chrome-nickel alloy wire, which is soft in texture an...

Abstract

The invention discloses a heating cable for geothermal heating. The heating cable comprises a heating element which comprises cold wires and a hot wire. The hot wire is arranged under the earth surface, and the cold wires are fixedly connected with the two ends and are led out of the earth surface to be connected with a power switch. The outside of the heating element is covered with an insulation layer, a shielding layer and a protection sleeve successively. The heating cable is made of chrome-nickel alloy wires and is soft in texture, fast in heating, stable in heat and safe to use; the insulation layer, the shielding layer and the protection sleeve further protect the usage safety of the heating cable from all sides.

Description

technical field [0001] The invention relates to a heating cable, in particular to a heating cable for geothermal heating. technical background [0002] In winter, indoors in the northern region are equipped with heating devices, from the original steam boiler heating to far-infrared carbon heating panels and various electric heater products, and now it has developed to use geothermal cables for indirect and effective heating. Among them, the biggest advantage of electric floor heating is precise control. No matter how the outdoor temperature changes, no matter how the heating cable fluctuates, due to the use of a very accurate electronic thermostat, the temperature of the ground surface and the air temperature in the room are basically very balanced. There will be no fluctuations, which cannot be compared with radiator heating and air conditioning heating. At the same time, electric floor heating will be equipped with a thermostat in each room, so it is easier to achieve ro...
