Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to an ultra-high temperature polyolefin insulated wire and cable. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals, usually consisting of several or groups of conductors. As society develops, electricity consumption also increases, and cables transmit electricity for people's use.

[0003] Traditional wires and cables still have some shortcomings. During use, cables are simply installed with a rubber sheath and conductor core. In high-temperature environments, cables are prone to combustion and fire. The flames can ignite the outer sheath, making it easy to damage the outer protective layer and causing spontaneous combustion damage, which reduces the safety and lifespan of the cable. To address this, we propose an ultra-high temperature polyolefin insulated wire and cable. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an ultra-high temperature polyolefin insulated wire and cable. Its advantages lie in providing double-layer heat insulation and flame-retardant protection for the cable, effectively enhancing its high-temperature resistance, thereby improving safety during use and extending its service life.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An ultra-high temperature polyolefin insulated wire and cable includes three cores and a high temperature resistant layer. The outer surfaces of the three cores are all covered with an insulation layer. The high temperature resistant layer is disposed outside the three insulation layers. A first filler layer is filled in the gap between the high temperature resistant layer and the three insulation layers. A waterproof layer is connected to the first filler layer. A flame-retardant component is disposed on the outer surface of the waterproof layer. An anti-wear component is disposed on the flame-retardant component.

[0007] The above technical solution achieves the following: by setting three insulation layers, the battery core not only has an insulating effect but also isolates the three battery cores from each other, further enhancing the insulation strength. The high-temperature resistant layer and flame-retardant components improve the cable's high-temperature resistance and flame-retardant effect. The first filler layer prevents friction between the three insulation layers and provides flame-retardant protection. The waterproof layer waterproofs the cable. Finally, the second filler layer improves the cable's wear resistance and extends its service life.

[0008] The present invention is further configured such that the high-temperature resistant layer includes a silicone rubber sleeve, an asbestos rope, and a polypropylene sheath, wherein the silicone rubber sleeve is bonded to the outer surface of the first filling layer, the asbestos rope is wound around the outer surface of the silicone rubber sleeve, and the polypropylene sheath is wrapped around the outer surface of the asbestos rope.

[0009] The above technical solutions achieve heat insulation, heat resistance, and high-temperature protection through the silicone rubber sheath and polypropylene sheath. The asbestos rope placed between the silicone rubber sheath and the polypropylene sheath effectively blocks heat transfer, further improving the cable's high-temperature resistance.

[0010] The present invention is further configured such that the flame-retardant component includes a flame-retardant strip layer, a flame-retardant tape layer, and a halogenated flame retardant, wherein the flame-retardant strip layer is bonded to the outer surface of the waterproof layer, the flame-retardant tape layer is bonded to the outer surface of the flame-retardant strip layer, and the halogenated flame retardant is sprayed onto the outer surface of the flame-retardant tape layer.

[0011] The above technical solution achieves good internal and external flame retardant effects through the flame retardant strip layer and flame retardant band layer, and the outer surface of the flame retardant band layer is sprayed with halogenated flame retardant, so that the inner wear-resistant sleeve can have flame retardant function.

[0012] The present invention is further configured such that the anti-wear component includes an inner anti-wear sleeve, multiple support frames and an outer anti-wear sleeve, the inner anti-wear sleeve is sleeved on the outer surface of the flame-retardant strip layer, the multiple support frames are connected in a ring at equal intervals on the outer surface of the inner anti-wear sleeve, and the inner surface of the outer anti-wear sleeve is connected to the outer surface of the multiple support frames.

[0013] The above technical solution involves multiple support frames positioned between the inner and outer abrasion sleeves, which enhances the robustness of the outer and inner abrasion sleeves during protection, thereby improving the cable's abrasion resistance.

[0014] The present invention is further configured such that the insulating layer is a polyethylene sheath.

[0015] The above technical solutions can insulate the battery cells and enhance the insulation strength between the three battery cells.

[0016] The present invention is further configured such that the first filling layer is filled with glass fiber.

[0017] The above technical solution can avoid friction between the three insulation layers and provide flame-retardant protection.

[0018] The present invention is further configured such that a plurality of second filling layers are filled between the outer anti-wear sleeve and the plurality of support frames.

[0019] Through the above technical solution, when the outer wear-resistant sleeve receives external pressure, it will squeeze out multiple second filling layers, which can buffer the impact force.

[0020] The present invention is further configured such that a plurality of second filling layers are filled with elastic rubber.

[0021] Through the above technical solution: when the outer anti-wear sleeve is subjected to pressure, it will squeeze multiple second filling layers of elastic rubber material. Then, under the action of external force, it can produce a large deformation, absorb the external force and reset, thus playing a good protective role for the internal structure of the cable.

[0022] The beneficial effects of this utility model are as follows:

[0023] An ultra-high temperature polyolefin insulated wire and cable, through the setting of a high temperature resistant layer and flame retardant components, can provide double-layer heat insulation and flame retardant protection for the three conductor groups in the first filling layer, effectively enhancing the high temperature resistance of the cable, thereby improving safety during use and extending the service life of the cable.

[0024] A type of ultra-high temperature polyolefin insulated wire and cable, by setting a second filler layer, can improve the overall robustness of the cable and give the cable a cushioning effect, thereby improving the cable's wear resistance and further extending the cable's service life.

[0035] Reference Figures 1-5 An ultra-high temperature polyolefin insulated wire and cable includes three battery cores 1 and a high temperature resistant layer 3. The outer surface of each of the three battery cores 1 is covered with an insulation layer 2. The high temperature resistant layer 3 is disposed outside the three insulation layers 2. A first filler layer 4 is filled in the gap between the high temperature resistant layer 3 and the three insulation layers 2. A waterproof layer 5 is connected to the first filler layer 4. A flame-retardant component 6 is disposed on the outer surface of the waterproof layer 5. An anti-wear component 7 is disposed on the flame-retardant component 6. The three insulation layers 2 not only provide insulation for the battery cores 1, but also separate the three battery cores 1 from each other, further enhancing the insulation strength. The high temperature resistant layer 3 and the flame-retardant component 6 improve the high temperature resistance and flame retardancy of the cable. The filling of the first filler layer 4 prevents friction between the three insulation layers 2 and provides flame retardant protection. The waterproof layer 5 waterproofs the cable. Finally, the second filler layer 8 improves the wear resistance of the cable and extends its service life.

[0036] Specifically, the high-temperature resistant layer 3 includes a silicone rubber sleeve 301, an asbestos rope 302, and a polypropylene sheath 303. The silicone rubber sleeve 301 is bonded to the outer surface of the first filler layer 4, the asbestos rope 302 is wrapped around the outer surface of the silicone rubber sleeve 301, and the polypropylene sheath 303 is wrapped around the outer surface of the asbestos rope 302. Through the action of the silicone rubber sleeve 301 and the polypropylene sheath 303, the cable can achieve the effects of heat insulation, heat resistance, and high-temperature protection. The asbestos rope 302 is placed between the silicone rubber sleeve 301 and the polypropylene sheath 303 to effectively block the transfer of heat and further improve the high-temperature resistance of the cable.

[0037] Specifically, the flame-retardant component 6 includes a flame-retardant strip layer 601, a flame-retardant band layer 602, and a halogenated flame retardant 603. The flame-retardant strip layer 601 is bonded to the outer surface of the waterproof layer 5, the flame-retardant band layer 602 is bonded to the outer surface of the flame-retardant strip layer 601, and the halogenated flame retardant 603 is sprayed on the outer surface of the flame-retardant band layer 602. The flame-retardant strip layer 601 and the flame-retardant band layer 602 can achieve good internal and external flame-retardant effects. The halogenated flame retardant 603 is sprayed on the outer surface of the flame-retardant band layer 602, so that the inner wear-resistant sleeve 701 has a flame-retardant function.

[0038] Specifically, the anti-wear component 7 includes an inner anti-wear sleeve 701, multiple support frames 702, and an outer anti-wear sleeve 703. The inner anti-wear sleeve 701 is fitted onto the outer surface of the flame-retardant tape layer 602. The multiple support frames 702 are connected in a ring at equal intervals on the outer surface of the inner anti-wear sleeve 701. The inner surface of the outer anti-wear sleeve 703 is connected to the outer surface of the multiple support frames 702. The multiple support frames 702 support the inner anti-wear sleeve 701 and the outer anti-wear sleeve 703, thereby improving the robustness of the outer anti-wear sleeve 703 and the inner anti-wear sleeve 701 when supported, thus improving the abrasion resistance of the cable.

[0039] Specifically, the insulation layer 2 is a polyethylene sheath. The polyethylene sheath of the insulation layer 2 can insulate the battery cell 1 and enhance the insulation strength between the three battery cells 1.

[0040] Specifically, the first filling layer 4 is filled with glass fiber. By filling the first filling layer 4 with glass fiber, friction between the three insulating layers 2 is avoided, and flame retardant protection is provided for them.

[0041] Specifically, multiple second filling layers 8 are filled between the outer abrasion sleeve 703 and multiple support frames 702. When the outer abrasion sleeve 703 receives external pressure, it will squeeze the multiple second filling layers 8. The multiple second filling layers 8 can buffer the impact and protect the internal structure of the cable.

[0042] Specifically, multiple second filling layers 8 are filled with elastic rubber. Under the action of elastic rubber, they can undergo large deformation under a small external force and recover after the external force is removed, thus providing good protection for the internal structure of the cable.

[0043] Working principle: The insulation layer 2, made of polyethylene sheath, not only insulates the battery core 1 but also provides a temperature resistance of 80℃ to 110℃. The silicone rubber sleeve 301 and polypropylene sheath 303 provide heat insulation, heat resistance, and high-temperature protection. An asbestos rope 302 placed between the silicone rubber sleeve 301 and the polypropylene sheath 303 effectively blocks heat transfer, further improving the cable's high-temperature resistance. The flame-retardant strip layer 601 and flame-retardant tape layer 602 provide good internal and external flame retardancy. A halogenated flame retardant 603 is sprayed onto the outer surface of the flame-retardant tape layer 602, giving the inner wear-resistant sleeve 701 a flame-retardant function. Finally, multiple support frames 702 support the inner and outer wear-resistant sleeves 701, improving their robustness and thus enhancing the cable's wear resistance.
