Problems solved by technology

In the existing technology, there are many kinds of alloy wires with copper as the parent material, trying to achieve the best effect, but all kinds of copper alloys have their own advantages and disadvantages in their functions, so we can only choose the one that takes into account the main basic functions. Balancing effect, so it is difficult to achieve the desired level
Composite conductors with copper-clad steel technology have appeared in foreign countries, which has reduced the difficulty of balance selection in some aspects, but it has not been generally recognized in practice due to the difficulties and defects in production and use.

Embodiment Construction

[0014] like figure 1 As shown, the electrified railway steel-clip-copper combined special-shaped contact wire is realized by the combination of the conductive part 1 and the steel cable part 2. The conductive part 1 is made of a copper-silver alloy with outstanding conductivity and wear resistance. The upper and lower sides are concentric and correspondingly arc-shaped with the same diameter. Two concave semicircular grooves are designed on the upper parts of the two straight sides. The steel cable portion 2 is made of strong, anti-corrosion, prestressed spring steel, and its diameter is equal to the semicircular groove of the conductive portion 1 .

[0015] When in use, the conductive part 1 and the steel cable part 2 are spread, hoisted and leveled synchronously, the steel cable part 2 is embedded in the groove of the conductive part 1, and the special clip is fixed as a whole for hanging.

[0016] Except for the technical features described in the instructions, all are kn...

Abstract

The invention relates to a copper-clad steel combined special-shaped contact wire for an electrified railway. The contact wire comprises a conductive part and a steel cable part, and is characterized in that the conflicting basic functions such as conductivity, wear resistance, tensile resistance, vibration resistance and fatigue resistance of the contact wire are separated and are combined and realized by the characteristic conductive part and steel cable part. Compared with the prior art, the copper-clad steel combined special-shaped contact wire for the electrified railway has the advantages of separated functions, complementary effect, strong combination, high conductivity, wear resistance, tensile resistance, vibration resistance and fatigue resistance, long service life and low cost, is easy to manufacture and convenient to use and is safe, reliable, energy-saving and environment-friendly, so that the contact wire is high in popularization and use value.

Description

1. Technical field: [0001] The invention provides a contact wire, specifically a special-shaped contact wire combined with copper and steel for an electrified railway. 2. Background technology: [0002] Contact wires are an important component and technical link of electrified railways. With the increase of speed, the requirements for comprehensive functional factors such as conductivity, wear resistance, pull resistance, vibration resistance, fatigue resistance and joint spacing of contact wires are getting higher and higher. In the existing technology, there are many kinds of alloy wires with copper as the parent material, trying to achieve the best effect, but all kinds of copper alloys have their own advantages and disadvantages in their functions, so we can only choose the one that takes into account the main basic functions. Balancing effect, so it is difficult to achieve the desired level. Composite conductors with copper-clad steel technology have appeared abroad, ...
