Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical wiring technology, specifically a high-temperature resistant and flame-retardant electrical wiring with a separator frame. Background Technology
[0002] Electrical wiring is an essential component of residential indoor power lines, used to transmit electrical energy from the distribution network to various electrical terminals within the home. Although simple in structure, electrical wiring is widely used and consumed in enormous quantities; its overall performance has a significant impact on the electrical safety of countless households.
[0003] A current publication (CN209625884U) discloses a flame-retardant electrical wire for fixed installation, comprising: a conductor core and a flame-retardant insulation layer and a flame-retardant laying layer sequentially wrapped around the conductor core. The flame-retardant laying layer includes a flame-retardant laying layer body and a first laying rib, a second laying rib, a third laying rib, and a fourth laying rib evenly distributed on the flame-retardant laying layer body. The first and second laying ribs are spirally distributed clockwise around the center of the flame-retardant laying layer, while the third and fourth laying ribs are spirally distributed counterclockwise around the center of the flame-retardant laying layer. This design avoids damage from external objects during installation, making the wire more stable after installation, and significantly improving the wire's high-temperature resistance and flame-retardant properties.
[0004] While existing technologies can achieve a certain flame-retardant effect, their shielding effect is poor. Therefore, we propose a high-temperature resistant flame-retardant electrical wire with a separator frame. Utility Model Content
[0005] The purpose of this invention is to provide a high-temperature resistant and flame-retardant electrical wire with a separator frame to solve the problems in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant flame-retardant electrical wire with a separator frame, comprising a separator frame and multiple wires, wherein the multiple wires are separated by the separator frame, and the separator frame and the multiple wires are covered by a flame-retardant wrapping layer, the gap after the flame-retardant wrapping layer is filled with flame-retardant filler, a first shielding layer is covered on the outside of the flame-retardant wrapping layer, a second shielding layer is covered on the outside of the first shielding layer, an outer insulation layer is covered on the outside of the second shielding layer, and the separator frame is provided with grooves at equal intervals.
[0007] Preferably, the cross-sectional shape of the groove is triangular or circular arc.
[0008] Preferably, an anti-tension rope is provided at the center of the separator.
[0009] Preferably, the tensile rope is made of tensile fiber rope or steel wire rope.
[0010] Preferably, the wire consists of an inner insulation layer and a conductor, with the conductor covered by the inner insulation layer.
[0011] Preferably, the first shielding layer is an aluminum foil layer, and the second shielding layer is a copper wire braided layer.
[0012] Compared with the prior art, the beneficial effects of this utility model are: Flame-retardant wrapping and flame-retardant fillers can effectively slow down the spread of flames. Even in high-temperature or localized fire scenarios, they can reduce the damage of flames to wires, reduce the risk of fire spread and leakage, and are suitable for use environments with high requirements for flame retardancy and high temperature resistance.
[0013] The double shielding of the aluminum foil layer and the copper wire braid layer not only isolates external electromagnetic interference (ensuring the stability of conductor current / signal transmission) but also prevents internal electromagnetic waves from leaking out. At the same time, the copper wire braid layer also enhances the mechanical protection of the wire, reducing damage to the wire from impacts and wear, and extending its service life.
[0014] The central tensile rope can directly withstand external pulling forces, preventing damage to internal components such as conductors and insulation layers due to pulling. This enhances the wire's resistance to loss during installation (such as high-altitude pulling and long-distance wiring) or use, and reduces failures caused by structural damage.
[0015] The recessed design of the divider enhances the flexibility of the wires, making them easier to bend and adapt to different laying paths (such as turns and narrow spaces); at the same time, the physical separation of the wires by the divider reduces the problems of wire tangling and interference during installation, improving wiring efficiency.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.
[0019] Please see Figure 1-2 In this embodiment of the present invention, a high-temperature resistant flame-retardant electrical wire with a separator frame includes a separator frame 1 and multiple wires. The multiple wires are separated by the separator frame 1 to prevent wear of the insulation layer caused by contact friction between the wires. The separator frame 1 and the multiple wires are covered by a flame-retardant wrapping layer 5. The gaps after the flame-retardant wrapping layer 5 is covered with flame-retardant filler 4. The double flame-retardant structure can significantly improve the flame-retardant performance of the wire, delay the spread of flame, and reduce the risk of fire. The flame-retardant wrapping layer 5 is covered with a first shielding layer 6, and the first shielding layer 6 is covered with a second shielding layer 8. The shielding layer 6 is made of aluminum foil to shield external electromagnetic interference and reduce the outward radiation of electromagnetic waves generated by the current inside the wire. The second shielding layer 8 is made of copper wire braiding, which enhances the shielding effect and improves the mechanical protection capability of the wire, resisting minor external impacts or wear. The outer side of the second shielding layer 8 is covered with an outer insulation layer 9. The partition frame 1 has grooves 11 at equal intervals. The cross-sectional shape of the grooves 11 is triangular or arc-shaped. While the partition frame 1 separates the left and right sides, the grooves 11 can improve the flexibility of the partition frame 1, reduce the rigidity of the partition frame itself, and increase its bending flexibility.
[0020] A tensile rope 7 is provided at the center of the separator 1. The tensile rope 7 is made of tensile fiber rope or steel wire rope to improve the overall tensile strength of the wire and prevent damage to the internal structure caused by external pulling during laying or use.
[0021] The wire consists of an inner insulation layer 2 and a conductor 3, with the conductor 3 covered by the inner insulation layer 2.
[0022] The working principle of this utility model is as follows: the flame-retardant wrapping layer is directly wrapped around the outside of the separator and the wire, forming the first flame-retardant barrier, which can prevent external flames from directly contacting the core components such as the conductor and separator inside the wire, and delay the burning of the internal structure by the flames; the gap between the flame-retardant wrapping layer and the separator and the wire is filled with flame-retardant filler, which blocks the channels through which the flames may spread, prevents the flames from seeping in or spreading from the gaps, further inhibits the speed of flame spread, and reduces the risk of fire expansion.
[0023] First shielding layer (aluminum foil layer): Aluminum foil has excellent electromagnetic reflection characteristics. On the one hand, it can reflect electromagnetic interference signals in the external environment and prevent them from penetrating into the wire and affecting the stability of current / signal transmission in the conductor. On the other hand, it can block the electromagnetic waves generated when the internal conductor is energized from radiating outward, thus avoiding electromagnetic interference to surrounding electronic equipment. The second shielding layer (copper wire braided layer): The braided mesh structure of copper wire can fill the gaps that may exist in the aluminum foil layer, further enhancing the integrity of electromagnetic shielding. At the same time, the copper wire itself has a certain mechanical strength, which can improve the wire's ability to resist minor external impacts and friction, thus taking into account both shielding function and mechanical protection.
[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
