Problems solved by technology

[0002] In the 21st century, my country has become the main exporter of rail vehicle technology. As one of the main accessories, signal transmission cables for rail vehicles have also fully realized their own autonomy; as an indispensable transmission link in the electrical system of rail vehicles, the signal transmission cable The requirements for cable reliability and durability are getting higher and higher under the trend of technology update of rail transit; however, the existing signal transmission cables need to be improved in pressure resistance. When the outer coating layer is scratched or When damaged, it will have a huge impact on the compression resistance of the cable. At the same time, in order to meet the shielding performance of the cable, the thickness of the aluminum sheath is thicker, the bending radius of the cable is larger, and it is heavy and difficult to lay.

Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] attached Figure 1-3 For the high-reliability signal transmission cable production process described in the present invention, comprise the following steps:

[0033] Step 1: Prepare the insulated single wire 4. First, the coiled copper wire is drawn and annealed by a continuous annealing wire drawing machine, and then the insulating layer 3 is extruded outside the copper wire through an extruder to make the insulated single wire 4; the insulating layer 3 is made of The polyethylene material makes the insulation of the cable better and can improve the stability of the cable.

[0034] Step 2: Prepare the four-wire group 2, and twist four insulated single wires 4 of different colors together through a high-speed star stranding machine to form the four-wire group 2; wherein the surface of the four-wire group 2 is fixed by twisting...

Abstract

The invention relates to a high-reliability signal transmission cable production process. The process comprises the following steps: preparing an insulating single wire, preparing a four-wire group, preparing a cable core, preparing an insulating belting layer, preparing a conductive shielding thermal insulation layer, preparing an aluminum protection wear-resistant sleeve, preparing an anticorrosive layer, preparing a lining buffer layer, preparing an armored waterproof layer, preparing an outer sheath layer, and obtaining a signal transmission cable. According to the invention, the cable has good tensile bending resistance, good insulation shielding performance, long service life and high reliability, can effectively shield external electromagnetic interference and the like, improves the transmission quality, and is beneficial to popularization and application.
