Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a wear-resistant cable with good flame retardant effect. Background Technology

[0002] Power cables, as a vital medium for modern power transmission, play a crucial role in densely populated or enclosed public places such as shopping malls, buildings, subways, and stations. To avoid obstructing pedestrian traffic and for aesthetic reasons, these cables are typically laid at the base of walls and corners. However, in the event of a fire, the burning of these power cables not only leads to communication disruptions and lighting failures but also severely hinders firefighting efforts, resulting in significant economic losses and personal injury.

[0003] Existing power cables often suffer from insufficient flame retardancy and poor abrasion resistance due to limitations in materials and design. These problems are particularly pronounced under extreme conditions such as fires, seriously threatening people's lives and property. Therefore, this invention provides a wear-resistant cable with good flame retardant properties to meet these needs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A wear-resistant cable with good flame retardant effect includes a cable body, wherein the cable body has multiple metal conductors for power transmission inside, each of the metal conductors is covered with an insulation layer, and the multiple metal conductors are wrapped with a filler layer; and a reinforcing component, which is used to enhance the strength of the cable body and is connected to the cable body.

[0006] Optionally, the reinforcing component includes a heat insulation layer bonded to the outside of the filler layer, the heat insulation layer being made of aerogel.

[0007] Optionally, a flame-retardant layer is provided on the outside of the heat insulation layer, and the flame-retardant layer is made of ceramicized silicone rubber.

[0008] Optionally, the flame-retardant layer is provided with a wear-resistant layer on the outside, and the wear-resistant layer is made of polyurethane.

[0009] Optionally, a triangular support portion is provided at the connection between the wear-resistant layer and the flame-retardant layer, a protrusion is provided on the outer side of the wear-resistant layer, and a rhomboid deformation cavity is provided inside each protrusion, and a recess is provided between every two protrusions.

[0010] Optionally, the filler layer is made of polypropylene.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects:

[0012] In the above solution, a reinforcing component is incorporated to enhance the overall strength of the cable body, using aerogel as the material. Aerogel, with its excellent thermal insulation properties, effectively blocks heat transfer, thereby reducing the risk of cable damage under extreme conditions such as fires. Ceramicized silicone rubber rapidly forms a hard ceramic layer when heated, effectively preventing the spread of flames and improving the cable's flame-retardant properties. Polyurethane, with its superior abrasion resistance and tear strength, protects the cable from external environmental damage, extending its service life.

[0013] In the above scheme, the triangular support inside the wear-resistant layer and the external protrusion and deformation cavity design further enhance the cable's resistance to deformation and structural strength, and improve the cable's reliability and stability. Attached Figure Description

[0025] like Figures 1 to 2As shown, this embodiment of the present invention provides a wear-resistant cable with good flame-retardant effect, including a cable body. Inside the cable body are multiple metal conductors 2 for power transmission. Each metal conductor 2 is covered with an insulation layer 3. The multiple metal conductors 2 are wrapped with a filler layer 1. A reinforcing component is used to strengthen the cable body and is connected to the cable body. The reinforcing component includes a heat insulation layer 4 bonded to the outside of the filler layer 1, the heat insulation layer 4 being made of aerogel. A flame-retardant layer 5, made of ceramicized silicone rubber, is provided outside the flame-retardant layer 5, made of polyurethane. The filler layer 1 is made of polypropylene. The cable body contains multiple metal conductors 2 for power transmission, which are tightly wrapped by the insulation layer 3 to ensure safe current transmission. The multiple metal conductors 2 are wrapped with a filler layer 1, providing necessary structural support and protection for the cable. The reinforcing component consists of the following layers: a heat insulation layer 4, bonded to the outside of the filler layer 1, made of aerogel. Aerogel is a material with extremely low thermal conductivity and excellent thermal insulation properties. It effectively blocks heat transfer and reduces the risk of cable damage under extreme conditions such as fires. The flame-retardant layer 5, located outside the insulation layer 4, is made of ceramicized silicone rubber. This material rapidly forms a hard ceramic layer when heated, effectively preventing the spread of flames and improving the cable's flame-retardant performance. Located outside the flame-retardant layer 5, it is made of polyurethane. Polyurethane has excellent abrasion resistance and tear strength, protecting the cable from external environmental damage and extending its service life. The filler layer 1 is made of polypropylene. Polypropylene, with its lightweight and high strength, not only provides sufficient structural support for the cable but also reduces its overall weight, facilitating installation and maintenance. During normal operation, the internal metal conductor 2 transmits power, while the insulation layer 3 ensures that current does not leak to the outside. When the cable is affected by external heat sources (such as fire), the heat insulation layer 4 effectively blocks heat transfer, slowing the rise in internal cable temperature. If the heat continues to rise, the flame-retardant layer 5 quickly forms a hard ceramic layer, preventing the spread of flames. The wear-resistant layer 6 protects the cable from damage caused by the external environment, such as friction and abrasion. Through the dual protection of the heat insulation layer 4 and the flame-retardant layer 5, the risk of cable damage under extreme conditions such as fire is greatly reduced. The wear-resistant layer 6, made of polyurethane, has excellent wear resistance and tear strength, extending the cable's service life. The filler layer 1, made of polypropylene, provides sufficient structural support while reducing the cable's weight, facilitating installation and maintenance. This utility model cable exhibits excellent performance in flame retardancy, wear resistance, structural stability, and lightweight properties, meeting the high performance requirements of modern power transmission.

[0026] like Figures 1 to 2As shown, a triangular support portion 603 is provided at the connection between the wear-resistant layer 6 and the flame-retardant layer 5. A ring-shaped protrusion 601 is provided on the outer surface of the wear-resistant layer 6, and each protrusion 601 has a rhomboid deformation cavity 602 inside. A recess 604 is provided between every two protrusions 601. The triangular support portion 603 serves as the connection structure between the wear-resistant layer 6 and the flame-retardant layer 5, and its shape design enhances the connection strength between the two. When subjected to external forces, the triangular structure can more effectively disperse stress, preventing peeling between the wear-resistant layer 6 and the flame-retardant layer 5. The design of the protrusion 601 increases the contact area between the wear-resistant layer 6 and the external environment, improving the cable's wear resistance. Simultaneously, the rhomboid deformation cavity 602 inside each protrusion 601 can absorb energy when subjected to external forces, reducing the impact on the cable body. This design is similar to the shock absorption principle of car tires, which can protect the cable from external damage to a certain extent. The recessed portion 604 is located between every two protrusions 601, and its design mainly considers the cable's friction performance and stability. The recessed portion 604 can increase the friction between the cable and the ground or other objects, preventing the cable from being excessively worn during sliding. At the same time, the recessed portion 604 can also provide a certain degree of elastic support for the cable, improving the cable's stability during use. The design of the triangular support portion 603 enhances the connection strength between the wear-resistant layer 6 and the flame-retardant layer 5, preventing peeling between the two layers and improving the overall structural stability of the cable. The protrusions 601 and the diamond-shaped deformation cavity 602 inside them significantly improve the cable's wear resistance. The protrusions 601 increase the contact area between the wear-resistant layer 6 and the external environment, while the diamond-shaped deformation cavity 602 can absorb energy when subjected to external forces, reducing the impact on the cable body. The design of the recessed portion 604 increases the friction between the cable and the ground or other objects, preventing the cable from being excessively worn during sliding. Meanwhile, the recessed portion 604 also provides a certain degree of elastic support for the cable, improving its stability during use. Overall, these designs not only enhance the cable's abrasion resistance and flame retardancy but also optimize its structural stability and performance. This allows the cable to maintain excellent performance in complex operating environments, extending its service life.

[0027] In summary, the triangular support 603 at the connection between the wear-resistant layer 6 and the flame-retardant layer 5, the annular protrusion 601 on the outside of the wear-resistant layer 6 and the rhomboid deformation cavity 602 inside it, and the recess 604 between every two protrusions 601 all play a crucial role in improving the cable's performance. These designs not only enhance the cable's structural stability and improve its wear resistance, but also increase friction and stability, providing a strong guarantee for the cable's long-term use.

[0028] The working principle provided by this utility model is that the reinforcing component consists of the following layers: a heat insulation layer 4, bonded to the outside of the filler layer 1, made of aerogel. Aerogel is a material with extremely low thermal conductivity and excellent heat insulation performance. It can effectively block heat transfer and reduce the risk of cable damage under extreme conditions such as fire. A flame retardant layer 5 is located outside the heat insulation layer 4 and is made of ceramicized silicone rubber. This material rapidly forms a hard ceramic layer when heated, thereby effectively preventing the spread of flames and improving the flame retardant performance of the cable. It is located outside the flame retardant layer 5 and is made of polyurethane. Polyurethane has excellent wear resistance and tear strength, which can protect the cable from damage from the external environment and extend the cable's service life. The filler layer 1 is made of polypropylene. Polypropylene, with its lightweight and high strength, not only provides sufficient structural support for the cable but also reduces the overall weight of the cable, facilitating installation and maintenance. During normal operation, the metal conductor 2 inside the cable is responsible for power transmission, and the insulation layer 3 ensures that the current does not leak to the outside. When the cable is affected by external heat sources (such as fire), the heat insulation layer 4 can effectively block the transfer of heat and slow down the rise in the internal temperature of the cable. If the heat continues to rise, the flame retardant layer 5 will quickly form a hard ceramic layer to prevent the spread of flames. The wear-resistant layer 6 is responsible for protecting the cable from damage from the external environment, such as friction and wear. Through the dual protection of the heat insulation layer 4 and the flame retardant layer 5, the risk of cable damage under extreme conditions such as fire is greatly reduced.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
