A buried high temperature resistant charging pile cable

Abstract

The invention relates to the field of cable technology, and discloses a buried high-temperature-resistant charging pile cable, which includes a cable outer protective layer, and a cable stem insertion groove is opened in the middle of the cable outer protective layer, and the cable stem is inserted A cable core is plugged into the middle of the connecting groove, a first air inlet is opened on the upper surface of the outer protective layer of the cable, a second air inlet is opened on the lower surface of the outer protective layer of the cable, and a second air inlet is opened on the outer protective layer of the cable. The top of the right end is fixedly connected with an exhaust pipe. By pushing the two upper tuyere adjustment plates and the lower tuyere adjustment plate to slide to the middle of the first air inlet and the second air inlet respectively, the opening sizes of the first air inlet and the second air inlet are changed, thereby changing the cable outer protection The size of the wind speed inside the layer makes the wind speed faster, speeds up the heat transfer to the outside of the outer protective layer of the cable, and keeps the temperature of the outer protective layer of the cable from rising, thus achieving the effect of high temperature resistance of the buried cable.

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 popularization of new energy vehicles, more and more charging piles have been put into use. Due to the special installation environment of the charging piles, some cables need to be buried underground. Buried cables require an outer layer of the cable. It has better shear resistance and extrusion resistance, especially for direct buried cables, which generally provide an armor layer to the cable to provide a compression and shear resistance protection. However, this method will make the heat dissipation of the cable worse, the hardness of the cable will be improved, 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, since the armor layer is first sheared, When the ultimate shear fo...
