Embodiment Construction

[0019] The technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments.

[0020] A preparation process for a seamless ground wire disclosed in the present invention specifically includes the following steps:

[0021] a. Sheath straightening: Straighten the pulled brass tube through a straightening machine. The straightening machine will straighten at a speed of 20m / min, and at the same time ensure that the copper tube is straight and does not appear flat during the straightening process. The straightened brass tube passes through the straightening wheels for secondary straightening and shaping. The two straightening wheels are arranged in 3 groups horizontally and 3 groups vertically, and they also rotate at a speed of 20m / min;

[0022] b. Threading the cable core: the cable core formed by the copper stranded wire is inserted into the straightened brass tube through the winch, and after the cable core is ...

Abstract

The invention reveals a seamless through ground line preparation technology comprising the following steps: sheath straightening, penetrating cable core, rolling, annealing and post-processing. The seamless through ground line preparation technology uses the rolling step to reduce the sheath outer diameter, thus reducing the equipment occupation area, preventing fracture problems caused by the drawing process, realizing higher speed when compared with a horn technology, and improving the processing efficiency.

Description

technical field [0001] The invention relates to a cleaning process for copper strips, in particular to a preparation process for seamlessly penetrating ground wires. Background technique [0002] The railway through ground line is a kind of traction power supply return system, electric power supply system, signal system, communication and other electronic information systems, buildings, track beds, platforms, bridges, tunnels, sound barriers, etc. along the railway. Cable, which can keep the grounding potential of each working point in a wide range of railway electrical systems basically consistent, making the system equipment grounding safe and reliable, eliminating the unbalanced current caused by the potential difference between different equipment, and realizing the protection of personnel and equipment Effective and reliable protection. [0003] At present, according to the classification of the outer sheath material of the through-ground wire, there are mainly four ki...
