Istrumentation Cables
An instrumentation cable is a type of cable used to transmit electrical signals between devices in various control and measurement applications, such as in process control systems, power generation, and communication systems. These cables are designed to be highly resistant to electromagnetic interference and provide stable and reliable transmission of signals over long distances. Instrumentation cables typically have multiple insulated conductors with shielding and are available in various configurations, including screened and unscreened, armored and unarmored, and multi-core cables. They are widely used in industrial applications to connect various sensors, actuators, and control systems for accurate and reliable data acquisition and transmission.

Annealed Bare/ uniform coated with Tinned/Silver Platted, High Conductivity, and Electrolytic Grade Solid/Stranded/Flexible Conductor. (Generally manufactured with conductor sizes 0.25/0.5/0.75/1.0/1.5/2.5/4.0 sq. mm, conforming to BS EN 50228,BS: 5308 - (I & II), IEC-189 - (I & II), VDE 0815.


Conductor is insulated with 70/85/105oC. Grade General Purpose/HR PVC Compound/Solid/Cellular Polyethylene PP/PE, Halogen Free FRLS Polymeric Compounds like LSZH or any other dielectric material as per customers specification. The choice of insulation material to be used for any application is Dependent on :-

  • Conductor temperature
  •  Electrical characteristics required
  • Compatibility

These are the most common types of extruded material used in the manufacture of Instrumentation cables.

Cores are identified with a different type of color scheme as per requirement as below:-

  • BS EN 50228, BS: 5308 - I & II,
  •  As Per IEC, ITD or number Printing.
  •  As Per Customers Scheme.

Core/Pair Identification :-
Multi-Pair Cables :
The cores within a pair are identified by one of the following methods :

  • By printing a reference code on one insulated conductor, or both of them, that indicates the number of that single pair.
  • By a numbered non - hygroscopic tape applied over the pair.
  • By using different colour combinations to uniquely identify the pair.

In cables which make up a pair, triad or quad core wires are uniformly twisted together. Maximum lay length determined by customer needs and minimum crosstalk requirements is up to 80mm .

If required, Individual Shielding may be of Poly Aluminum [Thin Layer of Aluminum Foil bonded to Polyester Film] Tape with Annealed Tinned Copper Drain Wire. It prevents the shorting of adjacent shield and minimizes the cross talk and ground loops. A Tinned Copper drain Wire is installed to provide continuous contact with the shield and allow for connection to ground. Tinning the drain wire reduces galvanic corrosion between drain and shield.

Pairs/Triads/Quads are laid up with suitable lay. The outer most layers are right hand lay and successive layers are laid up with opposite lay. Then, a Melinex Tape is provided to bind up laid up Pair/Triad/Quad.

Overall shielded cable constructions are recommended for use in Instrumentation computer and control application where signals are transmitted in excess of 100 Mili volts except in areas where high voltage and current sources create excessive noise interference. If required, Overall l Shielding may be of Annealed Tinned Copper Braiding/Poly Aluminum [Thin Layer of Aluminum Foil bonded to Polyester Film] Tape with Annealed Tinned Copper Drain Wire. Braiding ATC Shield has high tensile Strength and provides better coverage in flexing application. They are easier to terminate. This provides effective shielding; cross talk and noise are kept to an absolute minimum.

The laid up pair/triad/quad after shielding are provided with an inner sheath, which may be either Extruded Inner Sheath or wrap with PVC Tape.

It is applied over inner Sheath. It may consist of galvanized Round Steel wires or galvanized Flat Steel Strips. Steel wire armoured cables are suitable for direct burial. One or more copper wires can be incorporated in the armour to increase the conductivity of the Armour where it is being used as an earth return.

It is applied over Armouring in case of Armoured Wire or over Inner Sheath in case of Unarmoured Cable. The Color of Sheath is Black,Grey or as per customer's choice.The cable jacket is resistant to sunlight, moisture and vapour penetration. The Sheath material may be General Purpose PVC, FR / HR / FRLS PVC / Low Smoke Zero Halogen Compound as per requirement of the specification.The choice of sheathing materials to be used for any application is dependent on :

  • Temperature
  • Flexibility
  • Electrical characteristics
  • Smoke and acid gas emission limitations
  • Water resistance
  • Exposure to UV

To simplify jacket removal, high tensile strength nylon Rip Cord is provided over laid up of pairs/triads/quads below the outer sheath in case of Unarmoured cable or below the Inner Sheath in case of armoured Cable.
