Problems solved by technology

[0011] During the use of these cables, there are induction currents, capacitive currents and leakage currents that are conducted along the axial direction of the cables, which will increase the ground potential of the cable shielding layer and easily cause safety accidents
[0012] In addition, the current production process of cable conductors, including CN102403051A, etc., is to design a wire drawing die to draw a wire conductor through a large drawing machine, and then twist the conductor produced by a cage stranding machine or a frame stranding machine. The problem is that the production efficiency of shaped wire conductor drawing is low and the energy consumption is large. The drawing speed of ordinary round wire can reach 24m / s, and the drawing speed of shaped wire does not exceed 12m / s.

Abstract

The invention discloses a long stator winding cable for magnetic levitation rail transit. The cable includes a conductor, and a conductor shielding layer, an insulating layer, an insulating shielding layer and a sheath are sequentially extruded outside the conductor; the sheath includes the following components by weight: 100 parts by weight of rubber base material, 45 parts by weight of conductive carbon black -65 parts by weight, 5-10 parts by weight of softening agent, and 7-9 parts by weight of crosslinking agent. The cable sheath of the invention has the characteristics of high strength, high tear resistance, flame retardancy and the like.

Description

technical field [0001] The invention relates to a long stator winding cable for magnetic levitation rail transit, which belongs to the field of cable production. Background technique [0002] Maglev transportation is the development direction of high-speed environmental protection and economy of rail transit. The speed of maglev can reach 500-1300km / h. It has the advantages of low noise, low loss, easy turning and strong climbing ability. The future development prospect is very broad. The demand for special medium-voltage flexible cables is very large. [0003] At present, my country's CRRC is responsible for leading the national key special research and development of 600km high-speed maglev. This project includes two sub-projects of 200km / h medium-speed maglev and 600km / h high-speed maglev. At present, two test lines are planned to be constructed: Zhuzhou Construction 4.5km with a speed of 200km / h / h maglev track, Qingdao will build a 5.5km maglev track with a speed of 600...
