High-Quality Armored Heating Cable

Armored heating cable (also known as mineral insulated heating cable) is an industrial heating device composed of a metal protective sheath (stainless steel/copper), an inorganic insulation layer (magnesium oxide/aluminum oxide), and an electric heating wire, compacted via a mold. It features pressure resistance, vibration resistance, explosion-proof properties, and can withstand operating temperatures up to 600°C.
Structure and Performance
Sheath Material: Made of metals such as stainless steel, copper, or copper-nickel alloy, offering high mechanical strength and corrosion resistance.
Insulation Layer: Composed of inorganic materials like magnesium oxide or aluminum oxide, which are high-temperature resistant and non-conductive, ensuring safety.
Pressure and Insulation Resistance: The finished product can withstand up to 1500VAC/1min, with an insulation resistance of ≥500MΩ (500VDC).
Application Scenarios: Suitable for petrochemical, nuclear energy, aerospace, building heating, and other fields, supporting pipeline tracing, equipment freeze protection, and high-temperature steam environments.
Typical Features
Explosion and Permeation Resistance: Resists oil, gas, and flame intrusion; maintains insulation performance even after 12 hours of immersion in water.
High-Temperature Adaptability: Withstands temperatures up to 800°C and supports high power output (250W/m).
Easy Installation: Supports customized power and shapes, equipped with movable thermocouples for multi-point temperature measurement.
Classification and Application
By Sheath Material: Stainless steel, copper, copper-nickel alloy, etc.
By Power and Usage: Divided into medium-temperature (300°C), high-temperature (600°C), and ultra-high-temperature (800°C) models.
