Spectrum Cable-Tech is a top-quality provider in the manufacturing of High-Bandwidth Cables and Screened Instrumentation Cables for telecommunications and other industries. Spectrum makes available Instrumentation Signal Cables, Solar Cable, PTFE Cables, Overall Screen Cables, Computer Shielded Cables, Multi Core Cable, Screened & Unscreened Instrument Cable, and many other types of wiring and cabling.

Best-quality cables increase the life of the product and give the maximum rate of return. We manufacture top-quality shielded cables and wire for any application, including maxi-Termi point connections. Instrumentation cables provide a vital communication link between control software and hardware and the systems that they control, whether it is printers or power switching units. Below you will find information on our Shielded Instrumentation cables; feel free to contact us with any further technical or application questions.

Conductor

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.

Dielectric

The 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 Dependant on :-

• Conductor temperature
• Electrical characteristics required
• Compatibility

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

Color of Dielectric

Cores are identified with a different type of color scheme as per the 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.

Pair/Triad/Quad :-

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 .

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

Laying Of Pairs/Triad/Quad

Pairs/Triads/Quads are laid up with a suitable lay. The outermost 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.

Rip Cord

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.
