Embodiment Construction

[0013] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0014] like figure 1 The preferred embodiment of the heat-insulated and pressure-resistant cable of the present invention shown includes a metal sheath 1, and the metal sheath 1 is covered with a heat-insulating layer 2, and the space between it and the heat-insulating layer 2 is filled with heat-insulating cotton. Layer 2 is provided with copper wire braided shielding layer 3, the thickness of copper wire braided shielding layer 3 is less than the thickness of heat insulation layer 2, and it is connected with heat insulation layer 2 through integral injection molding, and there is a wrapping layer 4 inside it. The layer 4 is covered with non-woven fabric, an...

Abstract

The invention discloses a heat-insulating and pressure-resistant cable, which comprises a metal sheath, which is covered with a heat-insulating layer, and is filled with heat-insulating cotton between the metal-sheathing layer and the heat-insulating layer, and copper wire braided shielding is arranged in the heat-insulating layer layer, the thickness of the braided copper shielding layer is less than that of the heat insulation layer, and it is connected with the heat insulation layer by integral injection molding. It is connected to the wrapping layer and the copper wire braided shielding layer. There is an armor layer inside the wrapping layer. The armor layer is embedded in the wrapping layer. There is a conductor on it. The conductor is embedded on the armor layer. The surface is covered with a sheath, and the heat-insulating and pressure-resistant cable of the present invention has strong protection, can effectively avoid the problem of surface damage, reduce the situation of being punctured, has good heat insulation performance, and can withstand a certain pressure to avoid The problem of deformation caused by the internal conductor reduces the number of maintenance and replacement and greatly prolongs the service life of the cable.

Description

technical field [0001] The invention relates to a cable, in particular to a heat-insulating and pressure-resistant cable. Background technique [0002] Existing power cables are extruded (wrapped) around the conductor with an insulating layer, such as overhead insulated cables, or several cores are twisted (corresponding to the phase wire, neutral wire and ground wire of the power system), such as overhead insulated cables with more than two cores, Or add a sheath layer, such as plastic and rubber sheathed wires and cables. With the rapid increase of power load, the performance requirements of power cables are getting higher and higher, and the existing power cables cannot meet the demand. If corresponding improvements are not made in time, the use site will also be limited to a certain extent, reducing the scope of use and reducing economic benefits. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above p...
