Problems solved by technology

At present, for some high-power heating cables used in a small space environment, the armored structure type is basically used. However, due to its relatively large size and low power, it is not easy to use and install, and the working effect is not good. Ideally, there is no better solution
[0003] The current geothermal cable electric heating technology, the construction method mainly consists of laying heat insulation layer, steel wire mesh, heating cable, over-temperature protection temperature sensor, and ground decoration layer. The laying and construction process will cause the heating cable to be damaged. Bending, which greatly affects the service life of the heating cable, if the construction is improper, it is easy to cause damage to the heating cable, so we need to design a heating cable with high flexibility and not easy to be damaged

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the embodiments in the accompanying drawings.

[0022] Such as figure 1 As shown, the flexible heating cable includes three heating units 2, each heating unit 2 includes three heating conductors 21 and a metal heating outer wall 22, and a magnesium oxide filler 23 is filled between the heating conductors 21 and the metal heating outer wall 22. The heating units 2 are divided by the central dividing device 1, and the central dividing device 1 plays a role of support and isolation in the entire flexible heating cable. Because the flexible heating cable integrates three heating units 2 in one cable, it improves the flexible heating cable. Therefore, in order to ensure that each heating unit 2 does not interfere with each other, a central dividing device 1 is provided. The central dividing device 1 includes a reinforcing core 11 and a dividing part 12, and the reinforcing core 11 and the dividing par...

Abstract

The invention provides a flexible heating cable which comprises a center division device, a heating unit, a flame retardant layer, a buffer layer, a shielding layer and an elastic nylon resin outer protective sleeve; the heating unit comprises three heating conductors and metal heating outer wall arranged at the externals of the heating conductors respectively; a magnesium oxide filler is chargedbetween each heating conductor and the corresponding metal heating outer wall; the center division device comprises a strengthened core and a division portion; and a connection colloid is arranged between the strengthened core and the division portion. The flexible heating cable has the properties of high flexible flexure resistance, high wear resistance and the like, has stronger mechanical strength and is not liable to damage and long in service life.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a flexible heating cable. Background technique [0002] Heating cables are mainly of two types: limited current type and constant current type in terms of performance, and can be divided into armored and unarmoured structures in terms of structure. According to different use positions, working environments and technical requirements, these two types can be used respectively. Types of heating cables. At present, for some high-power heating cables used in a small space environment, the armored structure type is basically used. However, due to its relatively large size and low power, it is not easy to use and install, and the working effect is not good. Ideally, there is no better solution yet. [0003] The current geothermal cable electric heating technology, the construction method mainly consists of laying heat insulation layer, steel wire mesh, heating cable, over-temperature p...
