Abstract

The invention relates to the field of cable manufacture, in particular to a production process of a cable for a high-speed train. The production process comprises the following steps of: regularly twisting a plurality of fine tin-plated copper wires with the same diameter layer by layer in the same direction at multiple times to produce a cable conductor core; and synchronously extruding an inner insulating layer and an outer insulating layer outside the produced cable conductor core, wherein one or two of phosphate ester and magnesium hydroxide are used as flame retardant in the inner insulating layer and the outer insulating layer. The cable which is produced by adopting the production process of the cable for the high-speed train has the advantages of good flexibility, strong impact resistance, good oil resistance, strong aging resistance and high-temperature and low-temperature resistance, and is more suitable for the high-speed train.

Description

Technical field [0001] The invention relates to a method for manufacturing a cable, in particular to a manufacturing process for a cable for high-speed trains. Background technique [0002] With the rapid development of social economy, rail transit has also experienced many speed increases. From the initial low-speed train to the current high-speed rail, the high-speed rail runs very fast, reaching 300-400 kilometers per hour, while the cable is a high-speed train. Indispensable, the cables used for high-speed trains must have strong impact resistance, vibration resistance, fuel oil resistance, and high temperature and low temperature resistance. If the oil resistance is low, the fuel oil will penetrate the cable insulation In the layer, the insulation layer will expand, which will eventually cause the insulation layer to rupture, affecting its normal use. The impact resistance and oil resistance of the existing high-speed train cables still need to be improved. Summary of the i...
