Abstract

The invention relates to a cable for high-power diesel locomotives and a manufacturing method thereof, which sequentially includes a conductor cable core, an inner insulating layer and an outer insulating layer from the inside to the outside; it is characterized in that: the components contained in the inner insulating layer And the corresponding parts by weight are: HDPE 10-20, EVA 30-55, flame retardant 21-32.5, compatibilizer 2.5-4, antioxidant 0.8-1.5, lubricant 0.3-5, crosslinking agent 2 ‑3; the components contained in the outer insulating layer and the corresponding parts by weight are: HDPE 10‑20, EVA 20‑30, flame retardant 21‑32.5, compatibilizer 3‑5, antioxidant 1.5‑3 , the lubricant is 0.5-0.8, the cross-linking agent is 2-5, and the colorant is 2-4; the conductor cable core is a plurality of thin tinned copper wires with the same diameter. The cable can be used in the environment of high oil pollution, high pollution and high humidity, and it also has the performance of anti-ozone. At the same time, the cable also has the characteristics of affordable price and easy maintenance.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable for high-power internal combustion locomotive vehicles and a manufacturing method thereof. Background technique [0002] In the case of energy costs and environmental costs that continue to restrict the economic development of various countries, low-energy and low-emission railway transportation has once again demonstrated the development vitality of the sunrise industry. Since the traction capacity of the high-power AC drive diesel locomotive is equivalent to the number of freight trains of 2 to 3 traditional diesel locomotives in the past, it is very suitable for the requirement of "more cargo and less emission" of China's freight railways, and its development in the railway transportation industry It provides a broad stage and also provides a broad platform for the matching cables. [0003] The use environment of cables for high-power diesel locomotive vehicles is: pol...
