Industrial Instrumentation Cables

Additional Details

Annealed bare/ uniform coated with Tinned/Silver Platted, High Conductivity, and Electrolytic Grade Solid/Stranded/Flexible Conductor.

DIELECTRIC

Conductor are insulated with General Purpose/HR PVC Compound/Solid/Cellular PE/PP/or any other dielectric material as per customers specification.

COLOUR OF DIELECTRIC :-

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

i) As per IS:1554[Pt-I]:88, 694:90.
ii) As Per IEC, ITD or number Printing.
iii) As Per Customers Scheme.

PAIR/TRIAD/QUAD :-

Two/Three/Four cores are uniformly twisted together to form a Pair/Triad/Quad with maximum lay length 80 mm/as per requirement of customer. The lay shall be so chosen as to minimize cross talk in the cable.

INDIVIDUAL SHIELDING :-

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 to connection to ground. Tinning the drain wire reduces galvanic corrosion between drain and shield.

LAYING OF PAIRS/TRIAD/QUAD. :-

Pair/Triad/Quad 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.

Instrumention cables are used in normal or hazardous area, with or without flame retardant properties, suitable for process control, A/D converters and other modern microprocessor based instrumentation circuits.These cables are designed to offer excellent resistance to noise and induction phenomena encountered in instrumentation circuits.Voltage grade 650/1 I OOVolts (U0/U). Conforming to standard specifications like IS 1554 (Pt-I), BS 5308 (Pt-I & 2), IEC 189 (Pt-l&2),VDE08l5&08l6etc.

Configuration

Multi-core/multi-pair/multi-quad laid up concentrically or in units.
