Problems solved by technology

[0003] Due to the large load current value of the cable used for the charging pile (up to 400A), the conductor of the cable is prone to heat when it is energized, and it is frequently dragged and moved during use. The destruction and corrosion of air oxidation, wet water environment, and acid-base compounds and other factors, therefore, put forward higher requirements for the performance indicators of cables for charging piles. Polyvinyl chloride is widely used due to its convenient processing, excellent flame retardancy and low price In the wire and cable industry, but its stability to light and heat is poor, and its unstable group containing chlorine atoms is easy to release hydrogen chloride under the action of alkali, heat, light and other conditions to form a conjugated structure, which in turn causes material deformation. Brittle, and the thermal conductivity of polyvinyl chloride is poor. Under high temperature conditions, it is easy to form thermal stress concentration and cause micro-decomposition. Therefore, the PVC cable material used in the existing new energy charging pile cables has poor thermal conductivity and poor aging resistance. The service life is greatly reduced. Therefore, it is a technical problem to be solved to provide a high thermal conductivity elastomer used in new energy charging pile cables.
