[0001] The invention relates to the technical field of power cables, in particular to an environmentally friendly and safe high-voltage smooth aluminum sheathed power cable. Background Art

[0002] With the booming global economy and the continued acceleration of urbanization, the demand for electricity, as the core energy source for the operation of modern society, has shown an explosive growth trend. As the key carrier of power transmission, power cables are widely laid in urban underground pipelines, industrial plants, transportation hubs and other corners, shouldering the important task of ensuring stable and efficient power transmission.

[0003] Existing, such as Chinese patent number: CN 115762865 A, a 220kV large-section new smooth aluminum sheath high-voltage power cable, specifically includes five-segmented segmented conductors, the segmented conductors are wrapped with semi-conductive nylon tapes, the semi-conductive nylon tapes are provided with ultra-smooth semi-conductive layers, and then ultra-clean XLPE insulation layers are provided on the outside, and then ultra-smooth insulation shielding layers, semi-conductive buffer water-blocking tapes are provided on the outside, and then smooth aluminum sheaths are provided, and hot-melt adhesive layers, insulating outer sheaths and extruded semi-conductive layers are provided on the outside of the smooth aluminum sheaths; this power cable solves the conventional problems of limited cable reeling capacity, corrugating knife rolling cable outer shielding layers, and easy cracking of aluminum sheath welds when corrugating, etc. in the corrugated aluminum sheath structure; it completely improves the problem that due to the presence of crests and troughs in the corrugated aluminum sheath, there are gaps between the semi-conductive buffer layers, resulting in poor electrical contact between the semi-conductive buffer layer and the metal sheath, resulting in discharge and causing corrosion or even breakdown of the aluminum sheath.

[0004] Although the above-mentioned equipment has improved the problems of local whitening, burning and cable breakdown of the buffer layer of the high-voltage cable, when the cable is used to transmit and transfer electricity, the surface of the cable will be affected by external factors and oxidized or damaged after long-term high-intensity use.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. During use of the present invention, when the outer surface of the cable is damaged and it is used in rainy weather, rainwater will penetrate into the interior of the cable from the damaged position. The waterproof film can block the penetrated rainwater to prevent the rainwater from continuing to penetrate into the interior. Subsequently, the water-blocking tape can absorb the penetrated rainwater and form a gel-like substance to block the water seepage channel. The water-absorbing and swelling material placed in the placement groove can further absorb and block the rainwater. At the same time, the water-blocking material in the storage box can fully absorb the rainwater to prevent the rainwater from continuing to penetrate into the cable. The waterproof cover can block the rainwater. The above structure and method can protect the cable to prevent the cable from short-circuiting and spontaneous combustion due to the influence of rainwater when transmitting electricity, thereby greatly reducing the maintenance cost of the cable.

[0017] 2. In the use of the present invention, when the cable is used to transmit electricity, its inner sheath is made of low-smoke halogen-free and highly flame-retardant PE material instead of ordinary PE sheath material. When the cable spontaneously combusts, the toxic gas and thick smoke released by the cable can be effectively reduced, so that the cable has better environmental protection and safety performance. The first insulation and the second insulation use polypropylene insulation instead of cross-linked polyethylene insulation, which avoids the problem of cross-linked polyethylene being difficult to completely degrade and causing marine pollution during the production and recycling process due to its low density and easy floating on the water surface. This greatly improves the recycling rate of the material and reduces pollution to the environment.

[0018] 3. When the present invention is in use, due to the diverse use environments of the cables, in some areas the cables will be gnawed by animals such as rats and ants, causing damage to the cables. At this time, under the action of the outer sheath, the wear resistance and tear resistance of the cable can be increased. At the same time, under the action of the ball, it can make it inconvenient for rats and ants to gnaw the cables, thereby protecting the cables. Moreover, under the action of the rubber strip, it can stimulate rats and ants to prevent them from gnawing the cables. Subsequently, under the action of sharp objects placed inside the storage box, the gnawing rats and ants can be harmed, thereby preventing rats and ants from further gnawing the cables, thereby protecting the cables and preventing the cables from being damaged by short circuits caused by rats and ants, thereby further reducing the maintenance cost of the cables.

[0019] 4. In use, the first wrap and the second wrap of the present invention are made of polyester tape, which can significantly enhance the compression, tension and torsion resistance of the cable. When the external environment causes wear to the cable, the first wrap and the second wrap can play a buffering and protective role, extending the service life of the cable and reducing the failure rate. The shielding layer can reduce the leakage of internal signals in the cable, prevent the signal from interfering with other nearby cables or equipment, ensure the normal operation of the circuit, and improve the stability and reliability of signal transmission. The first conductor and the second conductor are the main conductors in the cable, responsible for transmitting current, that is, transmitting electrical energy from the power plant or power source to the power user or equipment.

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.

The waterproof sleeve 25 is made of waterproof rubber, and the thickness of the waterproof sleeve 25 is 1-1.3 mm.

[0024] In this embodiment, when the cable surface is damaged and used in rainy weather, rainwater will penetrate into the cable from the damaged part. At this time, the water-blocking film 21 is made of high-density polyethylene, which has excellent water-blocking performance and chemical corrosion resistance, and can play a preliminary blocking role for rainwater, preventing rainwater from quickly penetrating into the cable. When rainwater penetrates into the installation sleeve 22, the water-blocking tape 221 on its surface can strongly absorb the penetrated rainwater and expand rapidly to form a gel-like substance to block the water seepage channel. Then, the water-blocking tape 221 placed inside the placement groove 233 can be placed inside the placement groove 233 to block the water seepage channel. Under the action of the powder, it also has water absorption and expansion properties, and can be used to fill the gaps in the cable to achieve a water-blocking effect, prevent rainwater from continuously penetrating into the cable, and protect the cable. In addition, under the action of the water-absorbing and expanding ointment stored in the storage box 242, it can swell when exposed to water to limit the penetration of water in the channel. At the same time, under the action of the waterproof cover 25, it can further protect the cable, prevent rainwater from continuously penetrating into the cable, and prevent the cable from short-circuiting and spontaneous combustion during power transmission, thereby greatly reducing the maintenance cost of the cable.

[0025] Embodiment 2, according to Figure 1 , Figure 2 , Figure 8 , Fig. 9 as well as Fig.10 As shown, the protection mechanism 3 also includes an outer sleeve 31, the outer wall of the outer sleeve 31 is provided with a plurality of balls 311, the inner wall of the outer sleeve 31 is provided with a fixed sleeve 32, the outer wall of the fixed sleeve 32 is provided with a plurality of insertion grooves 321, the inner walls of the plurality of insertion grooves 321 are provided with rubber strips 322 movably inserted, the inner wall of the fixed sleeve 32 is provided with a protective sleeve 33, the outer wall of the protective sleeve 33 is provided with a plurality of installation grooves 331, the inner walls of the plurality of installation grooves 331 are provided with a placement box 332 movably inserted, the outer sleeve 31 is made of chlorinated polyethylene, and the thickness of the outer sleeve 31 is 1-1.5mm, the rubber strip 322 is made of a mixture of rubber and a substance with a strong pungent taste, and sharp substances are stored inside the placement box 332.

[0026] In this embodiment, when the cable is damaged by rats and ants during power transmission, the outer sheath 31 can improve the wear resistance and tear resistance of the cable to prevent rats and ants from easily damaging the cable, and the ball 311 can reduce the friction of the outer surface of the outer sheath 31 to prevent rats and ants from gnawing on the cable. When the outer sheath 31 is damaged by gnawing, since the rubber strip 322 is made of a mixture of rubber and a substance with a strong pungent taste (capsaicin), when rats and ants gnaw on the rubber strip 322, the strong irritation of capsaicin will stimulate the rats and ants to prevent them from continuing to gnaw on the cable. Then, sharp objects (glass slag, glass fiber) placed inside the placement box 332 can cause damage to the mouth of the rats and ants, so that the rats and ants will no longer gnaw on the cable, thereby protecting the cable and preventing the cable from being damaged by short circuit caused by rats and ants during power transmission.

[0027] Embodiment 3, according to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the conductor structure 1 includes an inner sheath 11, the inner surface wall of the inner sheath 11 is provided with a first winding 12, the inner surface wall of the first winding 12 is provided with a second winding 13, a plurality of first insulating layers 14 are provided between the inner surface wall of the first winding 12 and the outer surface wall of the second winding 13, the inner surface walls of the plurality of first insulating layers 14 are all provided with a first conductor 141, the inner surface wall of the second winding 13 is provided with a shielding layer 15, the inner surface wall of the shielding layer 15 is provided with a second insulating layer 16, and the second insulating layer 16 is provided with a second conductor 141. The inner wall of the edge 16 is provided with a second conductor 17, the inner sheath 11 is made of low-smoke halogen-free and highly flame-retardant PE material, and the thickness of the inner sheath 11 is 1.2-1.5 mm, the first insulation 14 and the second insulation 16 are both made of polypropylene material, and the thickness of the first insulation 14 and the second insulation 16 is 0.8-1.5 mm, the outer wall of the inner sheath 11 is fixedly connected to the inner wall of the waterproof cover 25, and the outer wall of the water-blocking film 21 is fixedly connected to the inner wall of the protective cover 33.

[0028] In this embodiment, the conductor structure 1 is, from the outer layer to the inner layer, an inner sheath 11-a first wrap 12-a first insulation 14-a first conductor 141-a second wrap 13-a shielding layer 15-a second insulation 16-a second conductor 17, wherein the inner sheath 11 is made of a low-smoke, halogen-free, highly flame-retardant PE material instead of an ordinary PE sheath material, and when the cable spontaneously combusts, the toxic gas and smoke released by the cable can be effectively reduced, so that the cable has better environmental protection and safety performance, the first wrap 12 and the second wrap 13 are made of polyester tape, which can significantly enhance the compression, tension and torsion resistance of the cable, and when the external environment wears the cable, the first wrap 12 and the second wrap 13 can play a role of buffering and protection, extending the cable life. The service life of the cable is prolonged and the failure rate is reduced. The first insulation 14 and the second insulation 16 use polypropylene insulation instead of cross-linked polyethylene insulation, which avoids the problem of cross-linked polyethylene being difficult to completely degrade and causing marine pollution during production and recycling due to its low density and easy floating on the water surface. The recycling rate of materials is greatly improved and pollution to the environment is reduced. The shielding layer 15 can reduce the leakage of signals inside the cable and prevent signals from interfering with other nearby cables or equipment, ensuring the normal operation of the circuit and improving the stability and reliability of signal transmission. The first conductor 141 and the second conductor 17 are the main conductors in the cable, responsible for transmitting current, that is, transmitting electrical energy from a power plant or power source to a power user or equipment.

[0029] The working principle of the whole mechanism is as follows: when the cable is used to transmit electricity, the electricity is transmitted through the conductor mechanism 1, wherein the inner sheath 11 is made of low-smoke halogen-free and highly flame-retardant PE material instead of ordinary PE sheath material. When the cable spontaneously combusts, the toxic gas and smoke released by the cable can be effectively reduced, so that the cable has better environmental protection and safety performance. The first winding 12 and the second winding 13 can significantly enhance the compression, tension and torsion resistance of the cable. When the external environment wears the cable, the first winding 12 and the second winding 13 can play a role of buffering and protection, prolonging the service life of the cable and reducing the failure rate. The first insulation 14 and the second insulation 16 use polypropylene insulation instead of cross-linked polyethylene insulation, avoiding the cross-linked polyethylene in production and During the recycling process, due to its low density and easy floating on the water surface, it will be difficult to completely degrade and cause marine pollution, which greatly improves the recycling rate of materials and reduces pollution to the environment. The shielding layer 15 can reduce the leakage of internal signals in the cable, prevent the signal from interfering with other nearby cables or equipment, ensure the normal operation of the circuit, and improve the stability and reliability of signal transmission. The first conductor 141 and the second conductor 17 are the main conductors in the cable, responsible for transmitting current, that is, transmitting electrical energy from the power plant or power source to the power user or equipment to complete the transmission of electricity. When it is damaged in some areas due to the influence of animals such as rats and ants, the outer sheath 31 can improve the wear resistance and tear resistance of the cable to prevent rats and ants from easily damaging the cable. The cable is damaged, and the friction of the outer surface of the outer sheath 31 can be reduced under the action of the ball 311, which makes it difficult for rats and ants to gnaw the cable. When the outer sheath 31 is damaged by gnawing, since the rubber strip 322 is made of a mixture of rubber and a strongly pungent substance (capsaicin), when the rats and ants gnaw the rubber strip 322, the strong irritation of the capsaicin will stimulate the rats and ants, preventing them from continuously gnawing the cable. Then, the sharp objects (glass slag, glass fiber) placed inside the placement box 332 can cause damage to the mouth of the rats and ants, so that the rats and ants will no longer gnaw the cable, thereby protecting the cable. When the outer surface of the cable is damaged and used in rainy weather, rainwater will penetrate into the inside of the cable from the damaged part. At this time, by placing the sharp objects (glass slag, glass fiber) inside the placement box 332, the rats and ants can be injured. Under the action of the water film 21, it can play a preliminary blocking role for rainwater, preventing rainwater from quickly penetrating into the cable. When rainwater penetrates into the installation sleeve 22, the water-blocking tape 221 on its surface can strongly absorb the penetrated rainwater and expand rapidly to form a gel-like substance to block the water seepage channel. Subsequently, under the action of the water-blocking powder placed in the placement groove 233, it also has water-absorbing and swelling properties, which can be used to fill the gaps in the cable to achieve a water-blocking effect, preventing rainwater from continuously penetrating into the cable, and protecting the cable. Moreover, under the action of the water-absorbing and swelling ointment stored in the storage box 242, it can swell when exposed to water, limiting the penetration of water in the channel. At the same time, under the action of the waterproof sleeve 25, the cable can be further protected.It prevents rainwater from continuously penetrating into the cable, which may cause the cable to short-circuit and spontaneously combust during power transmission, greatly reducing the cost of cable maintenance.
