Abstract

The invention relates to the technical field of cables, and provides a preparation method of a high-temperature-resistant flame-retardant charging pile cable. The method specifically comprises the following steps: extruding a flame-retardant layer material onto a copper wire through an extrusion process, and performing cooling to 33-36 DEG C; extruding a heat insulation layer material on the copper wire through an extrusion process, and performing cooling to room temperature to obtain a cable; combining a plurality of cables and then wrapping the combined cables with a high-temperature-resistant polytetrafluoroethylene film; and finally extruding molten polyvinyl chloride on the obtained product through an extrusion process. According to the present invention, the prepared cable has characteristics of good flame retardant property, strong thermal stability and strong thermal decomposition resistance, and is suitable for being used as a charging pile cable.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a method for preparing a high-temperature-resistant and flame-retardant charging pile cable. Background technique [0002] In recent years, the development of new energy vehicles has become a global trend, and my country's new energy vehicle industry has also entered a stage of rapid development. New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. At present, the majority of new energy vehicles use electric energy as the driving force source. For new energy vehicles driven by electric energy, charging piles are essential, which can replenish new energy vehicles more safely and efficiently in a sh...
