Application

Thermocouple mineral insulated cable is widely applied in industry, are used for power and control circuits of critical equipment, such as Temperature measurement devices; a proven choice for high temperature probe fabrication.

Contruction
Itis made by placing one or more wire conductors inside a circular copper tube and filling the intervening spaces with dry magnesium oxide powder.

The overall assembly is then pressed between rollers to reduce its diameter (and increase its length).

Quality Control

Production process control
Key production stages, such as size measurement and strength testing, are monitored online to ensure product compliance at each stage. We implement real-time monitoring during processes like heat treatment and welding to ensure that process parameters align with design specifications.

Finished product quality test
100% inspection of finished products, including dimensions, strength, and resistivity, ensures that the product pass rate is above 99%.

* Chemical composition analysis: We have two spectrometers for confirming product compositions through spectral analysis.
* Structural analysis: Equipped with an electron microscope, we can analyze the microscopic structure of materials.
* Mechanical performance testing: Tests include tensile, impact, and elasticity assessments.
* Non-destructive testing: We use an X-ray inspection machine for scanning, radiographic testing, and methods like magnetic particle or penetration testing to ensure the products are free from cracks, porosity, or other defects.
* Appearance inspection: We check the surface of the products for smoothness, and ensure there are no scratches, rust, or other surface defects.
