Description

Technical Field

[0001] This utility model belongs to the field of overhead conductor technology, and specifically relates to a corrosion-resistant overhead conductor. Background Technology

[0002] Overhead conductors are a core component of power transmission systems, mainly used for erecting power transmission towers or poles to carry out power transmission tasks. Their design must take into account conductivity, mechanical strength and environmental adaptability. With the development of new materials and technologies, overhead conductors are also constantly evolving to adapt to the ever-increasing electricity demand and stricter environmental protection requirements.

[0003] Existing corrosion-resistant overhead conductors utilize protective layers for external protection, insulation layers for conductor insulation, and high-purity aluminum or coated steel cores as conductor layers. The multi-layered composite sheath of the protective layer protects against external corrosion and wear, while the composite insulation material of the insulation layer enhances insulation and corrosion resistance. High-purity aluminum and coated steel cores mitigate the risk of electrochemical corrosion. However, in actual use, overhead conductors are erected between transmission towers or poles. Strong winds can cause the conductors to sway, potentially leading to stretching or bending, which can damage them and affect their service life. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a corrosion-resistant overhead conductor that can provide deformation buffering while increasing the elasticity of deformation when blown by strong winds. This can effectively improve the mechanical strength and environmental adaptability of the conductor body, effectively improve tensile strength, and effectively extend the service life of the overhead conductor.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a corrosion-resistant overhead conductor, including a conductor body, the conductor body including a protective structure disposed on its inner and outer sides, an insulation structure disposed in the middle of the conductor body, and a steel core disposed in the center of the conductor body.

[0006] As a further improvement of this utility model, the protective structure includes a fluoroethylene propylene membrane disposed on the outside, a cross-linked polyethylene layer disposed inside the fluoroethylene membrane, and a polytetrafluoroethylene layer disposed inside the cross-linked polyethylene layer; a corrugated opening 1 is formed on the side of the cross-linked polyethylene layer near the transverse center of the conductor, and a corrugated opening 2 is formed on the side of the polytetrafluoroethylene layer away from the transverse center of the conductor; an elastic braided mesh is disposed between the corrugated opening 1 and the corrugated opening 2; multiple cavities 1 are formed on the cross-linked polyethylene layer, and a silicone rubber rod 1 is inserted into each cavity 1; multiple cavities 2 are formed on the polytetrafluoroethylene layer, and a silicone rubber rod 2 is inserted into each cavity 2.

[0007] As a further improvement of this utility model, the insulation structure includes an epoxy resin disposed inside a polytetrafluoroethylene layer, modified graphene disposed inside the epoxy resin, an aluminum foil layer disposed inside the modified graphene, a polyester composite film disposed inside the aluminum foil layer, a nickel-phosphorus plating layer disposed inside the polyester composite film, and a semi-conductive resistive water strip disposed between the nickel-phosphorus plating layer and the steel core.

[0008] As a further improvement of this utility model, an anti-corrosion coating is provided on the outer side of the fluoroethylene propylene membrane.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the tensile strength is enhanced by a cross-linked polyethylene layer placed inside the fluoroethylene propylene membrane, which delays cracking caused by salt spray environment, and the bonding strength and resilience are improved by a polytetrafluoroethylene layer.

[0011] Secondly, when strong winds blow the overhead conductors erected between transmission towers or poles, the elastic braided mesh between the first corrugation on the cross-linked polyethylene layer and the second corrugation on the polytetrafluoroethylene layer provides deformation buffering while increasing the rebound force of the deformation.

[0012] Thirdly, by using silicone rubber rod one on the cross-linked polyethylene layer and silicone rubber rod two on the polytetrafluoroethylene layer to further improve resilience, the mechanical strength and environmental adaptability of the conductor can be effectively improved, and the tensile strength can be effectively increased.

[0013] Fourth, graphene enhances interfacial bonding, while also improving insulation and corrosion resistance. A dense oxide film or chemically inert layer is formed by the combination of aluminum foil layer, polyester composite film and nickel-phosphorus plating layer, blocking the penetration of corrosive media.
