Armored heating cable is an industrial heating device composed of a metal sheath, inorganic insulation layer, and heating wire. It features high-temperature resistance, explosion-proof capability, and high mechanical strength, making it widely used in industrial pipeline tracing and equipment freeze protection. ?
Structural Features
Utilizes a seamless metal sheath (stainless steel/copper) to enclose the heating wire and a dense inorganic insulation layer (magnesium oxide/aluminum oxide). The structure is available in integrated and segmented types, supporting customized power and shapes. Insulation resistance ≥100MΩ (500VDC), withstand voltage up to 1500VAC/1min. ?
Application Scenarios
Suitable for industrial fields such as petrochemicals, nuclear facilities, and high-temperature steam environments, with a maximum operating temperature of up to 600°C. Its explosion-proof and waterproof characteristics make it perform exceptionally well in flammable, explosive, or humid environments, meeting needs such as pipeline tracing and equipment freeze protection. ?
Technical Advantages
?High-Temperature Resistance?: Continuous operating temperature can reach 250-400°C, with the outer sheath enduring up to 600°C.
?Mechanical Protection?: Metal sheath enhances impact resistance, while the inorganic insulation layer improves corrosion resistance.
