It also includes an isolation strip with a cross-shaped cross-section. The four cores are respectively arranged between adjacent two legs of the isolation strip. An insulating sleeve is arranged on the surface of the core. A tin foil layer is wrapped on the core and the isolation strip. A copper-plastic composite tape shielding layer is arranged on the inner surface of the braided layer. An aluminum-plastic composite tape protection layer is arranged on the outer surface of the braided layer. The sheath is sleeved on the surface of the aluminum-plastic composite tape protection layer, and a heat-insulating layer is arranged between the sheath and the aluminum-plastic composite tape protection layer. The structure of the present invention is reasonably designed.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a heat-insulating cable is provided, in order to achieve a more practical value. Content of the Utility Model

[0006] In order to solve the above technical problems, the utility model provides a heat-insulating cable to solve the problem that the prior art has a structure for cable heat insulation, but the current heat-insulating layered structure is an integral heat-insulating part, and its flexibility is relatively low, which is not conducive to the bending of the cable.

[0007] The purpose and effect of a heat-insulating cable of the utility model are achieved by the following specific technical means:

[0008] A heat-insulating cable includes:

[0009] At least one conductor, the conductor is coated with a temperature-resistant layer, and a plurality of isolation rings are arranged in an array along the axial direction of the conductor. The isolation rings are ceramic rings, and an inner insulating layer is coated on the outer periphery of the plurality of isolation rings. An armor is sleeved outside all the inner insulating layers, a filler is arranged between the armor and the inner insulating layer, and an outer insulating layer is coated on the outer periphery of the armor.

[0010] Further, a flexible ring is arranged between two of the isolation rings.

[0025] Embodiment:

[0026] As shown in the attached Figure 1 to the attached Figure 3 figures:

[0027] The present utility model provides a heat-insulating cable, comprising:

[0028] At least one conductor 11, the conductor 11 is coated with a temperature-resistant layer 12, the temperature-resistant layer 12 is provided with a plurality of isolation rings 121 arranged in an array along the axial direction of the conductor 11, the isolation rings 121 are ceramic rings, the outer periphery of the plurality of isolation rings 121 is coated with an inner insulating layer 13, an armor 15 is sleeved outside all the inner insulating layers 13, a filler 14 is arranged between the armor 15 and the inner insulating layer 13, and an outer insulating layer 16 is coated on the outer periphery of the armor 15.

[0029] In this embodiment, the conductor 11 is provided with a plurality of isolation rings 121 distributed in an array, so as to achieve the heat-insulating effect on the conductor 11. At the same time, since the isolation rings 121 are made of ceramic materials, they have better insulation performance. Such a structure also endows the cable with excellent bending performance and stronger applicability.

[0030] A flexible ring 122 is arranged between two isolation rings 121.

[0031] The flexible ring 122 is silicon dioxide powder.

[0032] Its silica powder serves as the spacer material between the isolation rings 121, ensuring that the isolation rings 121 can be arranged along the bending region as the conductor 11 bends. When the flexible ring 122 is squeezed, it will deform to adapt to the space formed by the two isolation rings 121. Thus, on the basis of heat insulation and insulation, good bending performance is ensured.

[0033] The materials of the inner insulation layer 13 and the outer insulation layer 16 are insulating rubber.

[0034] The materials of the inner insulation layer 13 and the outer insulation layer 16 are plastics.

[0035] The armor 15 is made of a steel mesh. The setting of the armor 15 plays a protective role in the structure inside the armor 15.
