Abstract
Description
Technical Field
[0001] This utility model belongs to the field of overhead cable technology, and in particular relates to an energy-saving overhead cable. Background Technology
[0002] Overhead cables are cables that are installed on supports such as utility poles or towers. They are mainly used for the transmission of electrical energy or signals. Compared with underground cables, overhead cables are less expensive and easier to install and maintain, but they are more susceptible to environmental influences. Nevertheless, they are still widely used in many situations.
[0003] Most energy-saving overhead cables have some drawbacks in use, such as the possibility of cracks appearing in the sheath due to cold weather, allowing moisture to seep into the cable. Additionally, overhead cables are exposed to various corrosive substances during long-term exposure to the atmosphere, which can damage the cable. Therefore, we propose an energy-saving overhead cable. Utility Model Content
[0004] The purpose of this utility model is to provide an energy-saving overhead cable to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides an energy-saving overhead cable, comprising an insulation layer and a plurality of energy-saving conductors, and further comprising:
[0006] A shielding layer is disposed on the circumferential sidewall of an insulating layer. A plurality of energy-saving conductors are disposed within the insulating layer. A shielding layer is disposed on the outer side of the insulating layer. An inner lining layer is disposed on the circumferential sidewall of the shielding layer. A waterproof layer is disposed on the circumferential sidewall of the inner lining layer. An anti-corrosion layer is disposed on the circumferential sidewall of the waterproof layer. A heat insulation layer is disposed on the circumferential sidewall of the anti-corrosion layer. A sheath layer is disposed on the circumferential sidewall of the heat insulation layer. An anti-corrosion coating is applied to the circumferential sidewall of the sheath layer.
[0007] In this technical solution, the insulation layer can prevent current conduction, buffer external forces to protect the conductor, seal against water and dust, and adapt to temperature changes to aid energy saving. The shielding layer can effectively shield external electromagnetic interference and prevent internal signal leakage. It also has good insulation properties, enhancing the cable's safety and stability. The inner lining layer provides good flexibility, effectively buffering the impact of external pressure on the cable's interior and resisting certain chemical corrosion. The waterproof layer effectively prevents moisture from entering the cable, exhibiting excellent waterproof performance, as well as certain mechanical strength and aging resistance. The anti-corrosion layer effectively resists the corrosion of acids, alkalis, salts, and other chemicals. It has good weather resistance, preventing cable damage due to corrosion and extending its lifespan. The insulation layer effectively reduces heat loss from the cable; it has a low thermal conductivity and good insulation performance, making the cable more stable under different ambient temperatures. The pores of the aerogel are extremely small, typically at the nanometer level, making it difficult for liquid water and corrosive substances to penetrate the material through these tiny pores. The sheath layer mainly plays a protective role, resisting mechanical damage and ultraviolet radiation, and is also waterproof and moisture-proof, providing protection for the internal structure of the cable. The anti-corrosion coating forms a dense protective film, effectively isolating corrosive media, and has superior anti-corrosion performance, extending the cable's lifespan.
[0008] In the above technical solution, the insulating layer is further described using silicone rubber sponge.
[0009] In this technical solution, silicone rubber sponge can prevent current conduction, buffer external forces to protect conductors, seal against water and dust, and adapt to temperature changes to assist in energy saving.
[0010] In the above technical solution, the shielding layer is made of silicone rubber material and the thickness of the shielding layer is 0.20 mm.
[0011] In this technical solution, silicone rubber material can effectively shield external electromagnetic interference and prevent internal signal leakage. At the same time, it has good insulation properties, which can enhance the safety and stability of the cable.
[0012] In the above technical solution, the inner lining layer is made of ethylene propylene rubber material, and the thickness of the inner lining layer is 2mm.
[0013] In this technical solution, ethylene propylene rubber provides good flexibility, effectively buffers the impact of external pressure on the inside of the cable, and can also resist chemical corrosion.
[0014] In the above technical solution, the waterproof layer is made of cross-linked polyethylene material and the thickness of the waterproof layer is 3.4 mm.
[0015] In this technical solution, cross-linked polyethylene can effectively prevent moisture from entering the cable interior. It has excellent waterproof performance and also has certain mechanical strength and aging resistance.
[0016] In the above technical solution, the anti-corrosion layer is made of neoprene rubber material and the thickness of the anti-corrosion layer is 3mm.
[0017] In this technical solution, chloroprene rubber can effectively resist the corrosion of chemicals such as acids, alkalis, and salts. It has good weather resistance and can prevent cables from being damaged by corrosion, thus extending their service life.
[0018] In the above technical solution, the insulation layer is made of aerogel felt material, and the thickness of the insulation layer is 5mm.
[0019] In this technical solution, aerogel felt can effectively reduce the heat loss of the cable. It has a low thermal conductivity, good heat preservation performance, and can make the cable more stable under different ambient temperatures. The pores of aerogel are very small, usually at the nanometer level, which makes it difficult for liquid water and corrosive substances to enter the interior of the material through these tiny pores.
[0020] In the above technical solution, the sheath layer is made of ethylene propylene rubber material and the thickness of the sheath layer is 3mm.
[0021] In this technical solution, ethylene propylene rubber mainly plays a protective role. It can resist mechanical damage and ultraviolet radiation, and it can also be waterproof and moisture-proof, providing protection for the internal structure of the cable.
[0022] In the above technical solution, the anti-corrosion coating uses graphene anti-corrosion coating material, and the thickness of the anti-corrosion coating is 80μm.
[0023] In this technical solution, the graphene anti-corrosion coating can form a dense protective film, effectively isolating corrosive media, exhibiting superior anti-corrosion performance, and extending cable life.
[0024] The beneficial effects of this utility model are:
[0025] 1. This energy-saving overhead cable features an inner lining that resists chemical corrosion, an anti-corrosion layer that effectively resists the erosion of chemicals such as acids, alkalis, and salts, and excellent weather resistance. This prevents cable damage due to corrosion and extends its lifespan. The insulation layer makes it difficult for corrosive substances to penetrate the material through its tiny pores. The anti-corrosion coating forms a dense protective film that effectively isolates corrosive media, providing superior corrosion resistance. This results in an overall device with extremely strong corrosion resistance, extending the cable's lifespan.
[0026] 2. This energy-saving overhead cable has an insulation layer that prevents current conduction, buffers external forces to protect the conductor, and is sealed to be waterproof and dustproof. The waterproof layer effectively prevents moisture from entering the cable's interior, exhibiting excellent waterproof performance.
