The layer includes a wrapping reinforcement layer, the inner wall of the wrapping reinforcement layer is connected with an elastic layer, the wire includes a triangular wire core, and the triangular wire core is closely arranged in the inner cavity of the wire, and the triangular wire core includes an aluminum-plastic triangular support frame, the inner wall of the aluminum-plastic triangular support frame is connected with an outer filling layer, and the inner cavity of the outer filling layer is provided with a core conductor, and the core conductor includes an inner shielding layer, and the inner wall of the inner shielding layer is connected with an insulating Layer, the inner wall of the insulating layer is connected with an inner filling layer, the inner cavity of the inner filling layer is provided with a conductor, and the outer wall of the conductor is wrapped with an isolation layer. The high-strength copper alloy cable for the rail vehicle has good telecommunication transmission performance. , with high-strength drag performance and long service life.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-strength copper alloy cable for rail locomotives. Background technique [0002] In recent years, the national rail transit has developed rapidly. The control of EMU and high-speed units has become more and more complicated, and there are more and more electrical control equipment, and the demand for cables will inevitably increase. Locomotives undertake the arduous task of transporting goods and personnel. It needs to be moved frequently during use, and it is easy to be dragged and squeezed by the machine when moving back and forth with the machine. This requires improving the temperature resistance level of the insulation to improve the current carrying capacity of the cable, and improve the mechanical and physical properties, oil resistance, tensile properties and adaptability of different insulation. In order to improve the safety performance of the cable, the traditiona...

Problems solved by technology

[0002] In recent years, the country's rail transit has developed rapidly. The control of motor train units and high-speed units has become more and more complicated. There are more and more electrical control equipment, and the demand for cables will inevitably increase accordingly. Locomotives undertake the arduous task of transporting goods and personnel. It needs to move frequently during use, and it is easy to be dragged and squeezed by the machine when it moves back and forth with the machine. This requires improving the temperature resistance level of the insulation to increase the current carrying capacity of the cable, and improving the mechanical and physical properties, oil resistance, and tensile properties of the insulation. Climate performance to improve the safety performance of the cable. The traditional ordinary cable will be damaged in about half a year, and the processing is difficult, the mechanical properties of the material are low, the electrical performance is poor, and the oil resistance is poor. Affects the use, threatens the safety of personal and property, and causes the loss of national property. Therefore, we propose a high-strength copper alloy cable for rail vehicles
