Armored MI Mineral Insulated Heating Cable

Armored insulated heating cable (also known as mineral insulated heating cable) is an industrial-grade heating device composed of a metal sheath, inorganic insulation layer, and heating wire. It features a seamless metal sheath encapsulating the heating wire and a dense inorganic insulation structure, offering properties such as pressure resistance, shock resistance, and explosion-proof capabilities.
Structural Features
Sheath Material: Made of metal materials such as stainless steel or copper, enhancing mechanical strength and high-temperature resistance.
Insulation Layer: Utilizes inorganic materials like magnesium oxide or aluminum oxide, resistant to high temperatures (up to 600°C) and impermeable.
Heating Wire: Designed with single or multiple wires, compacted into an integrated structure through molding.
Application Scenarios
Industrial Field: Widely used in petrochemicals, power energy, aerospace, and building heating.
Special Environments: Suitable for harsh conditions such as high-temperature steam environments, nuclear facilities, and pipeline tracing.
Performance Parameters
Pressure Resistance: 1500VAC/1min (entire cable) and 1200VAC/1min (heating element).
Insulation Resistance: ≥100MΩ (500VDC).
Temperature Range: Maximum operating temperature up to 600°C; complies with IEC800 standard when below 250°C.
Advantages
High Safety: Explosion-proof, moisture-proof, and radiation-resistant.
High Reliability: Long service life and low maintenance costs.
High Flexibility: Supports customized power and shapes, with movable thermocouples enabling multi-point temperature measurement.
