Description

Technical Field

[0001] The utility model relates to the technical field of copper-clad steel grounding wires, in particular to a copper-clad steel grounding wire for preventing oxidation. Background Technique

[0002] At present, copper wires are widely used in conductors, electrified railways, lightning protection wires for tall buildings, grounding wires for electrical equipment, etc. However, due to the excessive softness of copper wires, they are extremely prone to deformation. To solve the problem of easy deformation when directly using copper wires, the production of copper-clad steel wires has been promoted. Copper-clad steel grounding wires are composite materials that combine the excellent electrical conductivity and corrosion resistance of copper with the high strength of steel.

[0003] Copper-clad steel means that copper wraps around steel wire, that is, a composite wire with a copper layer wrapped around the outer periphery of the steel wire. It utilizes the skin effect of low-voltage high-frequency signals and travels along the surface in the high-frequency region. Therefore, as long as the thickness of the copper layer reaches a certain range, signals in a certain frequency band can be ensured to be transmitted. Copper plays the role of conducting weak electrical signals, while the steel wire plays a supporting role.

[0004] In the related technology, copper-clad steel ground wires are usually used in power engineering. Application number: CN 211181708U, which discloses a copper-clad steel wire. This device is provided with an insulating protective skin, which can prevent the wire from short-circuiting during use, and can also prevent the oxidation and yellowing phenomenon caused by the silver-plated layer being exposed to the air for a long time, strengthening the practicability of the wire. However, during the use of this device, by setting two different copper-clad steel wires to improve the tensile strength and anti-bending strength of the device, not only greatly increases the production difficulty of the device, but also this structural strength is insufficient, prone to deformation, and prone to cracking due to stretching and bending, thus shortening the service life of the device.

[0005] Therefore, it is necessary to provide a copper-clad steel grounding wire for preventing oxidation to solve the above technical problems. Content of the Utility Model
