Abstract
The invention relates to a copper-clad steel wire dropper for a contact network, in particular to a copper-clad steel wire dropper for a carrier-cable hanging contact wire in the field of metal materials for the contact network of electrified railways and urban rail transit. The copper-clad steel wire dropper is characterized in that according to the action and the performance requirement of the dropper in the contact network, firstly the type, the diameter, the mechanical property and the resistivity of the copper-clad steel wire are selected according to the regulations in electronic-industry standard SJ/T11411-2010 copper-clad steel wire; the requirement for the strength of the dropper is not high, but the dropper needs to be soft so as to be bent into a ring shape; soft copper-clad steel wires with the relative conductivity being 30%IACS or 40%IACS can be selected and used, the type is 30A and 40A respectively; the diameter phi of a single wire is 4.0mm, the tensile strength is more than or equal to 345MPa and 310MPa respectively, the elongation is more than or equal to 15%, the resistivity of the direct current is less than or equal to 0.05862Omega.mm<2>/m and 0.04397Omega.mm<2>/m. The copper-clad steel wire dropper has the advantages that by adoption of the technical scheme, the dropper material is with in combination of with excellent conductivity and corrosion resistance of copper and high strength of steel and low cost can be obtained; in addition, the surface layer of the dropper is made of copper and the material of the surface layer of the dropper is the same as that of the contact wire, the special treating procedure of a dropper wire clamp can be avoided, and the workload for installation, operation and maintenance of the dropper is reduced.
Description
Technical field
The invention belongs to electrified railway and urban rail transit contact network metal material field, relate to the copper clad steel wire dropper that a kind of catenary is hung contact wire.
Background technology
In the overhead contact line with catenary of electrified railway and urban rail transit contact network, install dropper, make each span in the situation that does not increase pillar, increase the hitch point to contact wire, improve sag and the elasticity of contact wire, improve the contact wire workmanship.In addition, by the adjustable in length catenary of adjusting dropper and the distance between contact wire, guarantee that contact wire meets technical requirements to the height of rail level.At present, the metallic material of used dropper mainly contains three kinds on the contact system: bronze soft whipping wire, stainless steel soft twisted wire and galvanized steel wire.The above two anti-corrosion performances are good, but price is higher; Although the latter is cheap, easy-to-rust.The invention provides a kind of coating-hubbing copper clad steel wire dropper.Because metallurgical binding has been realized at copper and steel interface, makes copper and steel be combined into an integral body.Therefore, this is that the high strength bond of a kind of good electric conductivity with copper, corrosion stability and steel is in the same place, and cheap dropper material.In addition, the dropper top layer is copper, is similar material with contact wire, can exempt the special processing operation of hanger ear, has reduced the work capacity of dropper installation, operation and maintenance.
Summary of the invention
The present invention is in order to solve the problems of the technologies described above, and provides that a kind for the treatment of process is simple, the less contact system copper binding wire dropper of operation and maintenance work capacity.
A kind of contact system copper clad steel wire dropper is produced for the copper clad steel wire dropper with the soft attitude copper clad steel wire of coating-hubbing production.
Among the present invention, selecting relative conductivity water temperature and depth is the soft attitude copper clad steel wire of 30%IACS, and its classification is 30A, tensile strength difference 〉=345MPa, dc resistivity≤0.05862 Ω mm2/m.
Among the present invention, selecting relative conductivity water temperature and depth is the soft attitude copper clad steel wire of 40%IACS, and its classification is 40A, and tensile strength is 〉=310MPa that dc resistivity is≤0.04397 Ω mm2/m.
Among the present invention, the percentage elongation of the soft attitude copper clad steel wire of selecting 〉=15%.
Among the present invention, select classification, diameter, mechanical property and the electrical resistivity of copper clad steel wire according to the regulation of electron trade standard SJ/T11411-2010 " copper clad steel wire ".
The invention has the beneficial effects as follows: can obtain the high strength bond of good electric conductivity, corrosion stability and the steel of copper is in the same place, and cheap dropper material, the special processing operation that simultaneously can exempt hanger ear has reduced the work capacity of dropper installation, operation and maintenance.
