Characteristics and requirements of charging pile cable materials
Charging pile cables serve as a critical link between the charging station and the vehicle, making their performance essential for safe and efficient operation. In addition to basic cable properties like insulation and flame resistance, these cables must also be flexible enough to withstand frequent bending. This means the overall hardness of the cable should not be too high. The materials used in charging pile cables are typically elastomers, primarily for the insulation and outer sheath layers. These materials need to offer excellent oil resistance, tear resistance, weather resistance, chemical resistance, heat resistance, and softness. Commonly used materials today include TPU (Thermoplastic Polyurethane), TPE (Thermoplastic Elastomer), and PVC-based elastomers.
Many companies around the world are actively involved in developing and supplying high-quality materials for charging pile cables. Internationally, companies like Tenor Eppes are leading the way, while in China, numerous domestic manufacturers are also making significant contributions. Notable Chinese enterprises include Antuopu, Sanbo Polymer, Wanma Polymer, Xiongya, Ding Qi Zhonghua, Kexin Polymer, Linyi Rubber, Oulongyou, Weifang Zhongxu, and China Guangdong Nuclear Delta. These companies are not only focusing on material development but are also engaging in strategic partnerships with cable manufacturers to ensure the production of reliable and durable charging cables. As the demand for electric vehicles continues to grow, the importance of high-performance charging cables will only increase, driving further innovation in material science and manufacturing techniques.
The composite terminal is a typical representative of the connector (CONNECTOR), which is composed of a plug (female) and a socket (male) to realize the connection function. For the transfer of voltage, current and signal, this series is characterized by safe, reliable and stable contact, and is mainly used in electric power, communication, industrial control and other industries.
