Shielded Instrumentation Cables manufactured by us are widely used for measurement & control in the field of electronics. We follow stringent quality control measures and fabricate cables that conform to the Indian as well as International Industry standards. Our Shielded Instrumentation Cables are suitable for maxi-term point connections and provide vital communication link between Sensing Devices & Read Out Equipment for analog & digital signals. Relemac Technologies Pvt. Ltd manufactures cables that have:
Annealed bare/ uniform coated with Tinned/Silver Platted, High Conductivity, and Electrolytic Grade Solid/Stranded/Flexible Conductor (Class 5) to BS 6360/ Annealed solid copper(Class 1),Stranded(Class 2).EC Grade copper as per IS: 8130 with conductor sizes ranging from 0.05 sq. mm to 10 sq. mm
Conductors are insulated with General Purpose/HR PVC Compound/Solid/Cellular PE/PP/XLPE /Special thermoplastic materials (LSZH) or any other dielectric material as per customer's specification.
Color 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, MIL Standards or number Printing.
iii) As Per Customers Scheme.
Two/Three/Four cores are uniformly twisted together to form a Pair/Triple/Quad construction with individual/ collective shields 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.
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 is 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.
If required, Overall 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 or double helical steel tape.
It is applied over Armoring in case of Armored Cable or over Inner Sheath in case of Unarmored Cable. The Color of Sheath is Black or Grey or as per client's choice. The Sheath material may be General Purpose PVC /HR/FR/FRLS PVC Compound/Halogen free polymeric (ZHLSF), Silicone, EPR or elastomeric insulation can be provided as per requirement of specification.
