Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to a compression-resistant electric wire and cable. Background Art

[0002] The cable protection method for cable lines that are buried deep and close to pile foundations or foundation pits can be to form isolation bodies through steel sheet piles, tree root piles, deep mixing piles, etc. to limit the displacement of the soil around the underground cable lines and prevent squeezing or vibration of the cable lines.

[0003] For example, a compression-resistant wire and cable with authorization announcement number "CN221811990U" uses a steel armor layer to provide excellent compression resistance for the cable conductors during use, solving the problem of poor tensile strength during use. However, the device is supported by hard steel, which makes the cable difficult to bend during laying, making the device inconvenient to lay. It also makes it difficult to perform fireproofing on the cable during use, reducing the device's functionality. Utility Model Content

[0004] The purpose of the utility model is to solve the problems of inconvenient laying and low functionality of the device, and to propose a compression-resistant wire and cable.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A pressure-resistant wire and cable is designed, comprising a metal braided layer and a wear-resistant layer. The inner wall of the wear-resistant layer is in contact with the metal braided layer, the inner wall of the metal braided layer is fixedly connected to the insulating layer, the inner wall of the insulating layer is fixedly connected to the thermal insulation layer, and multiple groups of wires are arranged inside the thermal insulation layer.

[0007] Preferably, the wear-resistant layer is made of hard rubber, and the insulating layer is made of hard rubber.

[0008] Preferably, the metal braided layer is made of stainless steel, and the heat insulating layer is made of aerogel felt.

[0009] Preferably, the wires are provided in six groups, and the wires are symmetrically distributed around the center of the thermal insulation layer.

[0010] The utility model proposes a pressure-resistant wire and cable, which has the beneficial effect that: through the cooperation of the thermal insulation layer and the metal braided layer, the cable needs to be bent when laying the cable, and the metal braided layer can make the cable extend in different directions. At the same time, the metal braided layer can support and protect the internal wires, so that the wires can resist a certain pressure. At the same time, under the action of the thermal insulation layer, the external heat can be isolated when there is a fire, and the heat generated by the wires when power is turned on can be isolated, thereby reducing the diffusion of heat and the probability of fire. By bending the metal braided layer, it is more convenient to lay the cable, and the probability of fire can be reduced, thereby improving the functionality of the device.

[0017] Refer to the attached Figure 1-4 : In this embodiment, a pressure-resistant wire and cable includes a metal braided layer 4 and a wear-resistant layer 5. The inner wall of the wear-resistant layer 5 is in contact with the metal braided layer 4, the inner wall of the metal braided layer 4 is fixedly connected to the insulating layer 3, the inner wall of the insulating layer 3 is fixedly connected to the thermal insulation layer 2, and multiple groups of wires 1 are provided inside the thermal insulation layer 2.

There are six groups of wires 1, and the wires 1 are symmetrically distributed around the center of the thermal insulation layer 2.

[0018] Working principle:

[0019] When using wires and cables:

[0020] When laying the cable, it is necessary to bend the cable. The metal braided layer 4 can allow the cable to extend in different directions. At the same time, the metal braided layer 4 can support and protect the internal wire 1, so that the wire 1 can withstand a certain pressure. At the same time, under the action of the thermal insulation layer 2, it can isolate the external heat when there is a fire, and at the same time, it can isolate the heat generated by the wire 1 when it is powered on, reduce the diffusion of heat, and reduce the probability of fire.
