Armored heating cable (also known as mineral insulated heating cable) is an industrial heating device composed of a metal protective sheath (stainless steel/copper), inorganic insulation layer (magnesium oxide/aluminum oxide), and heating wire compacted via mold. It is primarily used in petrochemical, power energy, aerospace, and building heating applications.

Core Features
Pressure and Shock Resistance: Withstands 1500VAC withstand voltage test (1 minute), featuring explosion-proof and corrosion-resistant properties.
High-Temperature Performance: Maximum operating temperature up to 600°C; suitable for low-temperature scenarios (＜250°C).
Structural Reinforcement: Oval cross-section sheath improves heat transfer efficiency; triangular reinforcement frame enhances mechanical strength; supports customized power and shape.

Application Scenarios
Pipeline Tracing: Suitable for high-temperature steam environments, nuclear facilities, and other high heat-resistance scenarios.
Equipment Freeze Protection: Commonly used for chemical pipelines, tank insulation, and deep well oil extraction heating.
Special Environments: Can be used submerged in water for extended periods, meeting demands of high-radiation environments such as nuclear industry.

Performance Indicators
Withstand Voltage Performance: Finished product withstand voltage ≥1500VAC/1 minute.
Insulation Resistance: Finished product insulation resistance ≥100MΩ (500VDC).
Impermeability: After full cable immersion in water for 12 hours, insulation resistance remains ≥100MΩ.
