Embodiment Construction

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings:

[0021] like figure 1 As shown, the cross-section of the electric wire 1 is semicircular, the circular arc faces upward, the middle part has a groove, and the lower end is a plane, and the power-taking device is in contact with the plane to increase the contact area and reduce power consumption. The material of the electric wire 1 is copper; The wire core 2 is embedded in the groove in the middle of the wire 1, and its material is stainless steel wire with good corrosion resistance and oxidation resistance. The diameter of the wire core 2 is 5 mm; there is a wire 1 above the wire core 2 The bell-shaped opening 3 is easy to connect with the overhead line pole. The width of the upper opening of the opening 3 is 5mm, the width of the lower opening of the opening 3 is 2.5mm, the height of the opening 3 is 3mm, and...

Abstract

The invention belongs to the technical field of wires, and concretely provides an overhead wire for a tram and a preparation method thereof. The overhead wire comprises a wire prepared by copper or an aluminium alloy. The wire has a semicircular cross section, and the arc surface faces upwards. A wire core is embedded into the center of the wire, the wire is equipped with an opening over the wire core, and the opening is shaped like a horn. The width of the upper portion of the opening is equal to the diameter of the wire core, and the width of the lower portion of the opening is equal to the half of the diameter of the wire core. The opening is sealed by an epoxy resin sealing layer. The wire core is a steel wire or a stainless steel wire. The beneficial effects of the invention are that the overhead wire enables an electricity obtaining device to obtain electricity, is high in intensity, exhibits good conductivity, and is suitable for production for small and micro enterprises.

Description

technical field [0001] The invention belongs to the technical field of electric wires, in particular to an overhead electric wire for electric vehicles and a preparation method thereof. Background technique [0002] On current trams or electrified railways, especially on high-speed rail lines, discharge wires are installed above the rails, and trams or trains contact the electric wires through power-taking devices to take power for the operation of trams or trains. [0003] The wires currently used are generally copper or aluminum alloy cables. In recent years, they have been gradually replaced by rare earth high-speed iron aluminum alloy cables. The use of copper or aluminum alloy cables has low strength and requires more overhead poles, which increases construction costs. Rare-earth high-iron aluminum alloy has high strength and good electrical conductivity, but its cost is high and the technology is difficult, so ordinary enterprises cannot implement it.
