Problems solved by technology

[0004] The existing ethylene-propylene rubber insulated rail transit cables use the continuous steam vulcanization pipeline production process, which not only has complex processes and high energy consumption, but also has high requirements for plant design and manufacturing equipment, and the investment is relatively large, especially for The technical level of the manufacturing personnel is extremely high
Since the sulfur pipeline is closed when starting up, the appearance of the cable cannot be observed intuitively, so the product quality is difficult to control, the yield rate is low, and the manufacturing waste is great. It is even more difficult to produce small-section cables, and the durability The temperature level can only reach 90°C, which is not conducive to the production of ethylene-propylene rubber insulated rail transit vehicle cables

Abstract

The invention relates to the technical field of rail transit vehicle cables, and particularly relates to a preparation technology for an irradiated ethylene-propylene rubber insulated rail transit vehicle cable. The preparation technology comprises a conductor drawing process, a conductor stranding process, a double-layer extrusion process, and an irradiation cross-linking process. The technology process is simplified, the production efficiency is doubled, and the labor cost is greatly reduced. In addition, the consistency of the product structure is greatly improved, and the controllability of the production process is very high.

Description

technical field [0001] The invention relates to the technical field of cables for rail transit vehicles, in particular to a preparation process for rail transit vehicle cables. Background technique [0002] In the 21st century, my country has become the main exporter of rail vehicle technology. As one of the main accessories, the cables for rail vehicles have also fully realized their own autonomy; as an indispensable transmission link in the electrical system of rail vehicles, the cable reliability and The requirements for durability are becoming higher and higher under the trend of technological renewal of rail transit; compared with polyolefin materials, ethylene-propylene rubber has better electrical insulation performance, weather resistance and ozone resistance, and also has softness. It is one of the ideal materials for cable insulation. [0003] Elastomer materials, such as TPV, TPE, TPU, etc., which have both the softness of rubber materials and the processing charac...
