Armored heating cables are industrial heating devices composed of a metal sheath, inorganic insulation layer, and heating wires. They feature high-temperature resistance, explosion-proof capabilities, and high mechanical strength, making them widely used in industrial pipeline tracing and equipment freeze protection.

Structural Features

Utilizing a seamless metal sheath (stainless steel/copper) to enclose the heating wires and dense inorganic insulation (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. Their explosion-proof and waterproof characteristics make them 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 withstanding up to 600°C.

Mechanical Protection: The metal sheath enhances impact resistance, while the inorganic insulation layer improves corrosion resistance.
