Mineral Insulated Cables


General has more than a quarter of a century’s experience in manufacturing high precision instruments for temperature and pressure measurements for a wide spectrum of processing industries. Continuous research and development programme coupled with a regular study of customer needs in the light of technological evolution has helped to design and manufacture a range of self - armoured mineral insulated cables. Their unique characteristics and performance capabilities were tested in hostile operating environments, including nuclear reactors over many years, which has helped to establish a leadership. 


• Manufactured in a variety of sizes and conductor combinations

• hermo-element protection from oxidation and corrosion

• Highly compacted mineral insulant, metal sheath and hermetically sealed termination ensure extra long
   life for a wide range of temperature sensing applications

• The metal sheath provides self-armouring and enables the small mass thermocouple to be installed in
   difficult situations

• The small mass high thermal conductivity of the insulant ensure rapid response to temperature change

• The stable EMF characteristics are achieved through controlled production and testing 


  • Insulation resistance test at ambient and at elevated temperature

  • Sheath ductility test

  • Calibration (for thermocouple cable)

  • Conductor ductility test

  • Water immersion test


  • Loop resistance test

  • Nitrogen leakage test for MI probes

  • Dimensional test 

  • Microstructure Analysis – On Request

  • Macro Analysis – On Request
