Buried high-temperature-resistant charging pile cable

Abstract

The invention relates to the technical field of cables, and discloses a buried high-temperature-resistant charging pile cable which comprises a cable outer protection layer, a cable core column inserting groove is formed in the middle of the cable outer protection layer, a cable core is inserted into the middle of the cable core column inserting groove, and a first air inlet is formed in the uppersurface of the cable outer protection layer; and a second air inlet is formed in the lower surface of the cable outer protection layer, and an exhaust pipe fixedly communicates with the top of the right end of the cable outer protection layer. The two upper air port adjusting plates and the two lower air port adjusting plates are pushed to slide towards the middle of the first air inlet and the middle of the second air inlet correspondingly, then the opening size of the first air inlet and the opening size of the second air inlet are changed, and therefore the air speed in the cable outer protection layer is changed, and the air speed is increased; thus, the outward transmission of heat in the cable outer protection layer is accelerated, and the temperature of the cable outer protection layer is kept not to rise, so that the effect of high temperature resistance of the buried cable is achieved.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a buried high temperature resistant charging pile cable. Background technique [0002] With the popularity of new energy vehicles, more and more charging piles are put into use. Due to the special installation environment of charging piles, some cables need to be buried underground. It has better shear resistance and extrusion resistance, especially for direct-buried cables, which generally provide an armor layer for the cable to provide a protection against compression and shear. However, this method will make the heat dissipation of the cable worse, and the hardness of the cable will increase, and the installation of the armor layer cannot solve the problem of the cable being sheared. When the shear point of the external force is relatively small, because the armor layer first bears the shear, When the ultimate shear force is reached, the entire armor layer is damaged, and the ...
