Description

Technical Field

[0001] This utility model relates to the field of wire technology, specifically to an environmentally friendly natural cross-linked polyolefin high-temperature resistant wire. Background Technology

[0002] Self-crosslinking low-smoke halogen-free flame-retardant polyolefin cable material offers a simpler manufacturing cost and a more energy-efficient crosslinking method than irradiated crosslinking materials. The process is simple and easy to operate, and the production cost of the product is lower. Compared with ultraviolet crosslinking materials, the material performance is more stable, the product performance is more stable, and the production efficiency and production method are more convenient.

[0003] For example, an environmentally friendly naturally cross-linked polyolefin insulated high-temperature resistant wire with authorization announcement number "CN211427868U" uses an extrusion process to uniformly and tightly cover the insulation layer in a circular shape onto the fire-resistant layer. Although the investment cost is high and the direct economic benefits to the enterprise are relatively small, it expands the product coverage. However, during production, the fire-resistant layer is placed on the outside of the conductor, causing multiple sets of conductors inside to be clustered together. When energized, the conductors generate heat, and the heat is amplified due to the clustering, increasing the risk of combustion. If a fire occurs, a large amount of manpower and resources are required for repair, making the device less environmentally friendly. Utility Model Content

[0004] The purpose of this invention is to solve the problem of the device being environmentally unfriendly, and to propose an environmentally friendly natural cross-linked polyolefin high-temperature resistant wire.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design an environmentally friendly natural cross-linked polyolefin high-temperature resistant wire, comprising an insulation layer and a metal braided layer. The inner wall of the insulation layer is fixedly connected to the metal braided layer, and the inner wall of the metal braided layer is fixedly connected to a fire-resistant layer. The fire-resistant layer has multiple sets of through holes inside, and the inner wall of the fire-resistant layer is attached to multiple sets of conductors. The inner wall of the fire-resistant layer is fixedly connected to a reinforcing rib, and the outer wall of the reinforcing rib is fixedly connected to multiple sets of support rods. One end of each set of support rods is attached to multiple sets of conductors.

[0007] Preferably, there are six conductors, and the conductors are made of copper.

[0008] Preferably, the insulating layer is a naturally cross-linked polyolefin material.

[0009] Preferably, the reinforcing rib is made of hard rubber, and the metal braided layer is made of stainless steel.

[0010] This utility model proposes an environmentally friendly, naturally cross-linked polyolefin high-temperature resistant wire. Its advantages include: when energized, multiple conductors are separated by a fire-resistant layer. The presence of rock wool within the fire-resistant layer limits the heat generated by each conductor to a certain range, effectively reducing the risk of rapid temperature rise and combustion caused by multiple conductors sticking together. The reinforcing ribs reduce the probability of conductor breakage. The support rods fix the spacing between conductors, ensuring they remain separated. The metal braided layer improves compressive strength, reducing the probability of damage from heavy objects. Simultaneously, the metal braided layer provides flexibility, offering both support and protection. By separating each conductor group, the probability of combustion is reduced, and the manpower and resources required for maintenance are decreased, making the device more environmentally friendly.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] See attached document Figure 1-5In this embodiment, an environmentally friendly natural cross-linked polyolefin high-temperature resistant wire includes an insulation layer 1 and a metal braided layer 6. The inner wall of the insulation layer 1 is fixedly connected to the metal braided layer 6, and the inner wall of the metal braided layer 6 is fixedly connected to the fire-resistant layer 2. In the event of a fire, the fire-resistant layer 2 protects the entire wire, ensuring that only the outer insulation layer 1 is damaged. The fire-resistant layer 2 still provides fireproof and insulation protection for the internal conductors. Furthermore, the outer wall of the conductors 3 themselves is also made of insulating material, which can effectively prevent leakage. The fire-resistant layer 2 has multiple sets of through holes inside. The inner wall of the fire-resistant layer 2 is attached to multiple sets of conductors 3. The inner wall of the fire-resistant layer 2 is fixedly connected to reinforcing ribs 4, and the outer wall of the reinforcing ribs 4 is fixedly connected to multiple sets of support rods 5. One end of each set of support rods 5 is attached to multiple sets of conductors 3. There are six conductors 3, and the material of the conductors 3 is copper. The insulation layer 1 is made of natural cross-linked polyolefin material, the fire-resistant layer 2 is made of synthetic mica tape and rock wool. Rock wool has good heat insulation and high-temperature resistance properties. The reinforcing ribs 4 are made of hard rubber, and the metal braided layer 6 is made of stainless steel.

[0020] Working principle:

[0021] When using naturally cross-linked polyolefin high-temperature resistant wires:

[0022] When energized, the multiple conductors 3 are separated by the fire-resistant layer 2. The presence of rock wool inside the fire-resistant layer 2 limits the heat generated by each conductor 3 to a certain range, effectively reducing the risk of rapid temperature rise and combustion caused by multiple conductors 3 sticking together. The reinforcing ribs 4 reduce the probability of conductors 3 breaking. The support rods 5 fix the spacing between multiple conductors 3, ensuring that they remain separated. The metal braided layer 6 improves compressive strength, reducing the probability of being crushed by heavy objects. At the same time, the metal braided layer 6 provides a certain degree of flexibility, acting as a support while maintaining flexibility.

[0023] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
