High-temperature control cables are fluoroplastic insulated high-temperature resistant control cables, belonging to the category of electrical instrument connection lines and transmission lines for automatic control systems. They are mainly suitable for high-temperature and harsh environments with special requirements such as mobile temperature resistance in industries such as metallurgy, power, petrochemicals, petroleum, and chemicals. Their AC rated voltage is 450/750V, using PTFE insulation and sheath materials, possessing characteristics such as resistance to high and low temperatures (-40℃ to +275℃), acid and alkali resistance, oil resistance, water resistance, abrasion resistance, resistance to corrosive gases, aging resistance, and non-flammability. They maintain stable electrical performance and mechanical strength under high-temperature conditions.
Depending on the sheath material, the long-term allowable operating temperature of the conductor is divided into 200℃ (fluoroplastic) and 260℃ (PTFE insulation). The laying temperature should not be lower than -20℃, and the allowable bending radius should not be less than 6-12 times the cable's outer diameter. The product conforms to the GB/T 3956-1997 conductor DC resistance standard, has an anti-electromagnetic interference shielding structure, and the outer sheath material includes fluoroplastics and silicone rubber.
