[0002] In cold areas, some pipelines, rail transit, gardens, automatic doors, etc. need to be heated partially, while other parts do not need to be heated. Using an integral heating belt for heating not only fails to provide the desired protection, but also causes damage to the equipment or death of flowers and trees. Therefore, segmented heating is required. Currently, series and parallel heating are commonly used, which is troublesome to install and prone to failure. Therefore, designing a heating belt that can heat in segments is a good way to solve this problem. Utility Model Content

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0017] like Figure 1-3 shown.
[0018] A multi-section intermittent heating line, consisting of a hot end 6 and a cold end 7, with black marks 8 between the two ends, the number of which can be determined by conventional calculation according to the length and temperature required for heating, such as Figure 1-3 The internal structures of the hot end 6 and the cold end 7 are roughly the same, and they both include a glass fiber core 1, a resistance wire 2 is wound on the surface of the glass fiber core 1, and the surface of the resistance wire 2 is covered with an internal insulating sheath 3, and the internal insulating sheath 3 is covered with a metal braided layer 4, and the metal braided layer 4 is covered in an upper insulating sheath 5. The cross-section of the hot end 6 is as shown in FIG. Figure 4 As shown, the cross section of the cold end 7 is as follows Figure 5 As shown, a conductor 9 is axially installed at the cold break that does not require heating, and the conductor 9 is electrically connected to the corresponding resistance wire 2 without resistance, so that the resistance wire 2 does not work and does not generate heat. In specific implementation, the conductor 9 can be located on the inner surface of the resistance wire 2, and the number of the conductors 9 can be 3 or more, and they can be evenly distributed or continuously arranged on the inner or outer ring of the resistance wire 2.
[0019] The working principle of the utility model is:
[0020] When the entire heating wire is conductive, the resistance wire 2 inside the hot end 6 begins to heat up, achieving heating. When the current flows through the resistance wire 2 at the cold end 7, due to the action of the wire 9, the current does not pass through the resistance wire with large resistance but enters the resistance wire of the next hot end through the wire. Therefore, the resistance wire at the cold end does not heat up, thereby achieving hot and cold zone heating.
[0021] The parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art.
