Mineral Insulated Cables (M.I. Cables)
We introduce our latest addition in the cable line which is the mineral – insulated, metal sheathed cable products. The applications of MI Cable are many such as blast furnace, atomic research, nuclear reactors, Kilns and many more. Our product catalogue will help you in understanding and selecting MI cables for your application requirements. We provide our customers from standard as well as custom made products according to the needs of the customer, our lines are flexible and ready to meet the demand.
We manufacture cables in four distinct product lines:

• Thermocouple cables for measuring temperature.
• RTD extension cables for use with resistance temperature devices.
• Micro – Heater cables for unique industrial heating applications.
• Mineral Insulated Power Cable Any Special Cable which requires high
• temperature and rugged insulation
Features of MI Cables
Sheathed Thermocouple Cables have an outer sheath of metal with Two to Eight Cores where positive and negative thermoelements run around Circular Pattern , embedded in MgO. Mineral Insulated Cables are suitable to high Mechanical, Chemical, and Electrical stability. Due to good Flexibility, Excellent mechanical strength, and pressure resistance, mineral insulated Thermocouples/RTD's can be installed in complex installations. One or more wire like conductors (cores) are embedded in a high insulation quality MGO and pressed into a metal tube (sheath) made of oxidation and corrosion resistant material. The entire combination is then processed using suitable forming steps to obtain the final dimensions.
• Mechanical Strength: The High Mechanical Strength of MI cables can be attributed to the compact structure of MI Cables consisting of densely packed insulation material MgO with tough metal sheath which firmly places the conductors in the compound. The banding radius in 3 to 5 times the outer diameter.

• Long Life: The manufacturing of MI Cables is such that it ensures long conductor life as the sheath and insulation present in the MI Cable help the wire stand against harsh environmental conditions. This helps in the accurate calibration.

• Corrosion and Scaling Resistance:MI Cable manufactured in our facility are corrosion and scaling resistant, so they can withstand harsh or unfavorable environmental conditions.

• Long Length: We provide long lengths of MI Cable which were not available in the past.

• Quick Response: Quick heat transfer takes place in the MI Cable due to high thermal conductivity and small mass, which assures fast and speedy response.

• Radiation Resistance: The Radiation Resistance feature of MI Cables is a boon in application which involves high radiation. These are widely used in the primary circuits and inside the core in the reactors.

• Safety: The MI Cables are highly fire resistant due to the use of insulation materials such as Mgo. These cables are highly recommended from safety point of view.

• Moisture/Pressure: The homogeneity in metal sheath help the cable to tolerate high external pressure by not allowing the flow of majority of liquid and gaseous particles.
Processing of MI cables
• Sintering Of MgO:Raw Mgo is hygroscopic, so it is to be sintered to remove the moisture contents from MgO. Then MgO is put inside the furnace at a temperature of 1280°C for around 5 hours.

• Drawing Of Sheath with Raw Materials: Reduce the diameter of MI cable step by step. Employing special equipments.

• Annealing Of Cable:Annealing of MI cable in a furnace having five zones at different temperatures depending on material types & properties

Testing And Calibration :
• Calibration at three temperature point. • Insulation resistance test. • Dimension test (conductor diameter, wall thickness, outer diameter. • Loop resistance test. • Continuity test etc.

• Packaging and Storage: Storing in dry & dust free atmosphere with proper tagging. The magnesium oxide insulation is hygroscopic. To prevent moisture penetration, both ends are sealed. Under extreme conditions some moisture absorption could take place in spite of the sealing , so a dry place is desirable for storage. When pieces are cut from stock lengths, the exposed ends to be sealed at once. If at all Moisture has entered, this will lower the insulation resistance and may prove troublesome in welding. Moisture Penetration can be corrected by heating the sheath.

• Tagging: Each coil is fitted with a temporary seal to prevent moisture ingress during storage and shipping. Each coil is tagged to uniquely identify it for traceability purposes.
