The long-term allowable working temperature of silicone rubber cable conductor is -80~180℃. It has high heat resistance and excellent cold resistance. It has excellent electrical insulation performance, which is relatively stable even when the temperature and frequency change or when it is damp. It has excellent corona resistance and arc resistance. There is no obvious change in performance after being exposed to the sun for several years. It has low water absorption and good mildew resistance. It has good thermal conductivity. It is particularly soft and easy to install. It is odorless, tasteless, and non-toxic, and has no adverse effects on human health. It is suitable for signal transmission, control and measurement systems of electrical instruments and distribution devices in high-temperature industries such as steel, smelting, power plants, coking plants, aviation, metallurgical machinery, and petrochemicals, as well as control, monitoring circuits and protection lines in places with high fire risks and high importance of fire protection in industrial and mining enterprises such as electric power and petrochemicals. It is used for a long time in the construction of major infrastructure projects in national pillar industries such as electric power, metallurgy, petroleum, and chemical industries, as well as in high-temperature and harsh environments.
