Heating cables can be divided into two types: single conductor heating cables and double conductor heating cables. Heating cables are often referred to as geothermal cables. The difference between double conductor heating cable and single conductor heating cable is that the interior of double conductor heating cable is welded by metal heating wire and two cores of copper conductor, and the double conductor heating cable itself forms a loop; At the tail of the heating cable, the heating cable core can be folded back, and only the terminal of the heating cable needs to be connected during wiring. Since the double conductor heating cable has its own circuit, all lines are at the same end. In the construction process, as long as the terminal is connected to the power supply, the terminal of the wiring is not required and can be placed arbitrarily according to the specific situation. Compared with single conductor heating cable, it greatly reduces the construction difficulty and is more and more favored by people. The heating cable is composed of alloy resistance wire, insulating layer, grounding wire, shielding layer and outer sheath. The alloy resistance wire is used for heating, and the operating temperature is between 50 ~ 60 ℃.
