The AFPF-250 3×7/0.2 fluoroplastic cable is a high-performance high-temperature cable. Its conductor is composed of 3 strands of copper wire, each strand consisting of 7 wires with a diameter of 0.2 millimeters. The insulation layer of this cable is made of fluoroplastic material, which has excellent high-temperature resistance and can work stably for a long time in an environment with a temperature of 250℃. Fluoroplastics also have good chemical stability, can resist the erosion of various chemical substances, are not easy to age, and have a long service life. In addition, the cable has excellent mechanical wear resistance and electrical insulation properties, low high-frequency loss, high insulation resistance, and high voltage resistance. This type of cable is widely used in industries with high requirements for cable performance, such as aviation, aerospace, electronics, and chemical industry, and can meet the special needs of these industries in high-temperature and highly corrosive environments. In terms of price, due to its high performance and special application scenarios, the AFPF-250 3×7/0.2 fluoroplastic cable is relatively expensive. However, the specific price will vary depending on factors such as the manufacturer and the purchase volume. At present, some professional cable manufacturers in China, such as Shanghai Shuangxu Electronics Co., Ltd. and Anhui Baineng Electric Co., Ltd., are producing and selling this type of cable. They provide high-quality products to the market with advanced production equipment and strict quality control systems.
