These thermocouple extension and compensating cables can also be termed as instrumentation cables, since they are used for process temperature measurement. The construction is similar to pair instrumentation cable but the conductor material is different. Thermocouples are used in processes to sense temperature and is connected to the pyrometers for indication and control. The thermocouple and pyrometer are electrically conducted by thermocouple extension cables / thermocouple compensating cables. The conductors used for these thermocouple cables are required to have similar thermo-electric (emf) properties as that of the thermocouple used for sensing the temperature. These thermocouple cables are manufactured as per IS:8784, ANSI-MC 96, 1, B.S., ENI, DIN and customers specification.
Shielded Cables (Multi Core Flexible Shielded Cables) in gray, black and white colour is available with us. These Shielded Cables are used to interconnect electrical measuring devices with instrument panel for measuring in engineering plants and in areas where signal transmission is distorted by electrical interference fields. Available in standard these Shielded Cables are also custom manufactured as per client's requirement.
Higher Ampacity: AAAC can carry at least 15-20% extra current as compared to ACSR of equal size.

We offer conductors for usage across medium & low voltage applications. These are corrosion resistant conductors exhibiting excellent resistance in sea coast and polluted industrial areas. These are accurately hardened on surface for reducing the damage to surface during handling. conductors have higher Strength to Weight Ratio thus every economical as it reduces the overall cost involved in transmission lines.
Lower Power Losses : since AAC is homogeneous (with all strands of Aluminium Alloy) with no steel component, the resistance of AAAC is lower as compared to that of ACSR.
Higher Ampacity : AAAC can carry at least 15-20% extra current as compared to ACSR of equal size.
Longer Life : Experience in foreign countries shows that all Aluminium Alloy Conductors are in service for over 60 years, which is about double the life of ACSR conductors.
Surface Hardness : The surface hardness of AAAC is 80 BHN as compared to 35BHN of ACSR. This reduces damage to surface during handling and therefore leading to lesser corona losses and radio interference at EHV.
Thermal Stability : AAA Conductors are stable upto 90°C against ACSR conductors which are stable upto 75°C.
Higher Strength to Weight Ratio : Since AAAC has higher strength to weight ratio, span car be increased from 2 to 15% resulting in overall reduction of cost in tower / supports and other accessories in transmission lines system.
