What are the materials of high voltage connectors? What are the domestic and foreign manufacturers of high voltage connectors?

High-voltage connector is a kind of connector for high-voltage current transmission, which is usually used in power system, rail transit and other fields. In order to ensure the reliability and stability of the connector in the process of high-voltage current transmission, the material of high-voltage connector usually needs to have high insulation performance, mechanical strength and corrosion resistance. High-voltage connectors are mainly made of the following materials: 1. Metal materials: usually made of copper, aluminum and other conductive materials, with high conductivity and mechanical strength, but need to be insulated to avoid short circuit between conductive materials. 2. Insulating materials, such as ceramics and porcelain-plastics, have excellent insulating properties and mechanical strength, but the cost is high and the production process is complex. 3. Polymer materials, such as polyimide and polyetherketone, have become one of the main materials for high-voltage connectors because of their excellent insulation, mechanical strength and corrosion resistance, as well as low cost. There are many manufacturers producing high-voltage connectors at home and abroad, and several representative manufacturers are listed as follows: 1. RST Company, Germany: RST Company is a company specializing in the research and development, production and sales of industrial connectors, and its high-voltage connector products are widely used in power systems, rail transit, aerospace and other fields. 2. Amphenol Corporation of the United States: Amphenol Corporation is a leading connector manufacturer in the world. Its high-voltage connector products have high reliability and stability, and have been applied to power systems and railway systems in many countries. 3. CSR Zhuzhou Electric Locomotive Research Institute Co., Ltd.: CSR Zhuzhou Electric Locomotive Research Institute is one of the major suppliers of China's railway system. Its high-voltage connector products have excellent reliability and stability, and have been widely used in many fields of China's railway system. 4. China Southern Power Grid Technology Co., Ltd.: China Southern Power Grid Technology Co., Ltd. is one of the major suppliers of power systems in China. Its high-voltage connector products have high reliability and stability, and have been applied to power systems in many countries. In a word, the materials and manufacturers of high-voltage connectors are diverse and diverse, and consumers can choose according to their own needs and budgets.
