High-temperature silicone rubber cable for railway rolling stock current collector

Abstract

The invention relates to the technical field of cables. The invention further discloses a high-temperature silicone rubber cable for the railway rolling stock current collector. The cable comprises aflexible memory metal tube with a hollow structure, and a heat insulation layer is arranged on the outer side of the flexible memory metal pipe; six connecting plates which are annularly and uniformlydistributed are fixedly connected between the inner ring of the heat insulation layer and the outer ring of the flexible memory metal pipe; a heat dissipation fiber layer is fixedly filled between the inner ring of the heat insulation layer and the outer ring of the flexible memory metal pipe; a cable core is arranged between two adjacent connecting plates, the cable core is fixedly embedded in the heat dissipation fiber layer, the outer ring of the heat insulation layer is fixedly connected with a shielding layer, the outer ring of the shielding layer is fixedly connected with an insulatinglayer, and the outer ring of the insulating layer is fixedly connected with a silicone rubber protective jacket. According to the high-temperature silicone rubber cable for the railway rolling stock current collector, heat generated by the cable core can be dissipated conveniently, a protective layer outside the cable is effectively prevented from melting, and the conductor of the cable core is not prone to damage due to heating.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-temperature silicon rubber cable for a current receiver of a railway locomotive. Background technique [0002] The current collector, also known as the current collector shoe, is a set of dynamic current receiving equipment installed on the train bogie to dynamically take current from the rigid power supply rail (third rail) for the train to meet the power demand of the train. On the basis of systematic research on the running posture of urban rail trains, the arrangement and characteristics of steel-aluminum composite power supply rails, the technical requirements for dynamic current receiving, electrical insulation requirements, and the matching requirements of friction pairs for dynamic current receiving, scientifically and reasonably Select the movement range of the swing rod, the contact positive pressure of the current-receiving friction pair, and the material of the ...
