Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0024] Such as figure 1 and 2 Shown, the technical scheme of concrete implementation of the present invention is:

[0025] Adopt a kind of contact cable 4 that wraps carbon fiber core with alloy material, be provided with carbon fiber core in the center of described cable, be wrapped with alloy layer 2 on the exterior of described carbon fiber core 1; Described alloy and described carbon fiber core are in In the horizontal continuous casting machine, or in the rolling and coating machine, or in the alloy coating device to compound into cables. The composite process of carbon fiber core and alloy layer in horizontal continuous casting machine is shown as ...

Abstract

The invention relates to an electric transmission cable, in particular to a contact cable taking alloy material to wrap the carbon fiber core for rapid transit ralway, which is characterized in that the center of the cable is provided with a carbon fiber core; the outside of the carbon fiber core is wrapped with an alloy layer; the alloy and the carbon fiber core are arranged in a horizontal caster, or in a rolling wrapping machine, or in an alloy dip-coating device to composite a cable. The alloy is sliver copper alloy or tin copper alloy or chromium zircomium copper alloy or cadmium copper alloy or magnesium copper alloy. The section of the surface of the cable is round after being treated by cold rolling and cold drawing. The two sides of the round section are symmetrically provided with two V-shaped cable-hanging grooves which are drawn from a cold-drawing die. Compared with the existing steel-core cable, the weight of the contact cable is greatly reduced, thus effectively solving the problem of the sagging of the cable, the contact cable can work under higher temperature, the core can resist corrosion and has not the problem of corrosion between metals, so the higher current-carrying capacity can be provided and the number of the cable stand can be effectively reduced.

Description

technical field [0001] The invention relates to power transmission and transformation cables, in particular to contact cables with reinforcing cores used in high-speed railways. Background technique [0002] With the rapid increase of railway speed, the aggravation of operational tasks and increasingly fierce competition, heavy-duty and high-speed railways (above 300Km / h) have become the development trend of the world's railway industry. The contact line used in railway operations is wheel-rail railway One of the key equipment for high speed. The strength of pure copper and copper-silver alloy contact wires currently used is only 350-400MPa, which is only suitable for medium and low speed (below 250Km / h) railways, and is difficult to meet the service conditions of high-speed railways. [0003] The existing contact wires for medium and low-speed railways at home and abroad generally adopt upward continuous casting, combined with cold working strengthening, so that their stre...
