Armored Heating Cable

Armored heating cables (also known as mineral insulated heating cables) are industrial heating devices composed of a metal sheath, inorganic insulation layer, and heating wire, featuring high-temperature resistance, explosion-proof capability, and high mechanical strength.
Structural Composition
Primarily consists of a continuous seamless metal sheath (stainless steel or copper), an inorganic insulation layer (magnesium oxide or aluminum oxide), and a heating wire, compacted into an integrated structure through molding. Some models are coated with a PE or low-smoke zero-halogen outer jacket to enhance corrosion resistance.
Key Features
Pressure and Explosion Resistance: Capable of withstanding 1500VAC/1min pressure tests with excellent shock resistance;
High-Temperature Endurance: Maximum operating temperature up to 600°C;
Safety and Reliability: Impermeable, explosion-proof, and waterproof, suitable for harsh environments such as nuclear energy and chemical industries;
Mechanical Strength: Utilizes triangular reinforcement frames and oval cross-sectional designs to improve heat transfer efficiency and durability.
Application Areas
Widely used in petrochemicals, nuclear facilities, high-temperature steam pipelines, building heating, and equipment freeze protection, with customizable power and shapes to meet diverse requirements.
