Description

Technical Field

[0001] The invention relates to the technical field of electric wires and cables, in particular to a protective type anti-aging electric wire and cable. Background Art

[0002] In today's era of rapid technological development, wires and cables are widely used in many fields as the core carriers of power transmission and signal transmission. However, existing wires and cables have exposed many defects in the face of increasingly complex and harsh use environments. In outdoor environments, long-term ultraviolet radiation, temperature changes, and erosion by humid air can easily cause aging of the cable's insulation layer and cracking of the sheath, thereby reducing the insulation performance and mechanical strength of the cable. In industrial environments, pollution from chemical substances such as acids and alkalis and the influence of electromagnetic interference can also pose a serious threat to the normal operation of cables, such as causing signal transmission distortion, increased power transmission loss, and even safety accidents. Therefore, the development of a wire and cable that can effectively resist the influence of multiple harsh environmental factors and has high protection and aging resistance has become a key issue that the industry needs to solve urgently. Summary of the invention

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] See also Figure 1 As shown, a protective anti-aging wire and cable comprises a cable body 1, wherein the cable body 1 is provided with an anti-aging outer layer 2, a steel belt armor 3, a shielding layer 4, a protective layer 5, a filling layer 6, an insulating layer 7 and a plurality of battery cells 8 in sequence from the outside to the inside;

[0016] The anti-aging outer layer 2 includes antioxidants, ultraviolet absorbers, heat stabilizers, carbon black and high-performance polymer matrix (polytetrafluoroethylene PTFE), and the thickness of the anti-aging outer layer 2 is between 8-9mm. Adding an appropriate amount of antioxidants to the anti-aging outer layer 2 can effectively prevent the performance degradation of the cable body 1 due to oxidation reactions during use. Common antioxidants such as phenols and amines can capture free radicals and inhibit the oxidation chain reaction, thereby extending the service life of the cable material; ultraviolet absorbers and carbon black can effectively resist ultraviolet radiation in the sun and convert them into harmless heat energy to be dissipated, thereby avoiding ultraviolet damage to the cable material; heat stabilizers can prevent materials such as polyvinyl chloride from degradation and discoloration at high temperatures by capturing decomposition products such as hydrogen chloride and replacing unstable chlorine atoms, ensuring the reliable performance of the cable under long-term high-temperature operation conditions; high-performance polymer matrix (polytetrafluoroethylene PTFE) has excellent aging resistance, high and low temperature resistance, oil resistance and water resistance, and can provide all-round protection for wires and cables, enabling them to operate stably for a long time in harsh natural and industrial environments.

[0017] The steel belt armor 3 is made of high-quality carbon structural steel. The steel belt armor 3 is spirally wound on the outside of the shielding layer 4, and a certain overlapping width is maintained between the steel belt armors 3, and the overlapping rate is between 20% and 50%. The steel belt armor can withstand greater pressure. When the cable is squeezed by a heavy object, the steel belt can disperse the pressure to prevent the insulation layer, conductor and other structures inside the cable from being flattened or damaged. At the same time, the hardness and toughness of the steel belt enable it to absorb and disperse impact energy, reduce damage to the internal structure of the cable, and ensure the integrity and normal function of the cable.

[0018] The shielding layer 4 is woven from copper wire and aluminum foil, and the shielding layer 4 is woven in a mutually perpendicular manner. The protective layer 5 is made of high-strength, wear-resistant polyamide (PA) material, and the thickness of the protective layer 5 is between 1-2mm. The shielding layer 4 woven from copper wire and aluminum foil has a good electromagnetic shielding effect, which can effectively prevent the influence of external electromagnetic interference on the internal signal transmission of the cable, and can also shield the internal signal of the cable from leaking out. The aluminum foil further enhances the shielding performance and plays a certain role in moisture and water resistance. The protective layer 5 made of polyamide (PA) material has excellent wear resistance, tear resistance and chemical corrosion resistance, and can effectively resist the external mechanical force, friction and erosion of chemical substances such as acid and alkali, protect the interior from damage, and extend the service life of wires and cables.

[0019] The filling layer 6 is made of glass fiber. The insulating layer 7 is made of cross-linked polyethylene (XLPE) and nano-ceramic powder. The thickness of the insulating layer 7 is 1-2 mm. The battery core 8 is formed by twisting multiple strands of high-purity oxygen-free copper wires; the insulating layer 7 is wrapped around the outside of the battery core 8, and the filling layer 6 is arranged on the outside of the battery core 8 wrapped by multiple insulating layers; the filling layer 6 made of glass fiber can maintain stable performance and will not melt or deform due to high temperature, thereby ensuring the integrity of the cable structure, and its insulation performance can further enhance the insulation effect of the entire cable and prevent accidents such as electrical breakdown; the insulating layer 7 isolates multiple battery cores 8 from each other to prevent short circuits between the core wires, ensuring that each core wire can independently transmit current or signals, and at the same time prevents harmful substances such as external moisture, dust, corrosive gases, etc. from contacting the conductive core wires, avoiding these substances from causing corrosion or other damage to the core wires, thereby extending the service life of the cable, and also ensuring the safety and stability of the cable operation; the battery core 8 formed by twisting multiple strands of high-purity oxygen-free copper wires has excellent conductivity and low resistivity, which can effectively reduce the loss in the process of power transmission, and at the same time the twisted structure helps to improve the flexibility and tensile strength of wires and cables, and adapt to different laying environments and use requirements.

[0020] The working principle of a protective aging-resistant wire and cable: the aging-resistant outer layer made of antioxidants, UV absorbers, heat stabilizers, carbon black and high-performance polymer matrices and the protective layer made of polyamide (PA) material can effectively prevent the performance degradation of the cable body due to oxidation reactions during use, and can also effectively resist ultraviolet rays in the sun and convert them into harmless heat energy and dissipate them, thereby avoiding ultraviolet damage to cable materials. At the same time, it can effectively resist external mechanical forces, friction, and corrosion by chemicals such as acids and alkalis, so that it can provide all-round protection for wires and cables, allowing them to operate stably for a long time in harsh natural and industrial environments; at the same time, the steel belt armor 3, shielding layer 4, filling layer 6 and insulating layer 7 ensure that the wires and cables can ensure the integrity and normal function of the cables in harsh environments, protect the interior from damage, and thus extend the service life of the wires and cables.
