Instrumentation Cables

Application:

Instrumentation cables are used to connect various instruments for communicating with each other or with the control systems, mainly in process plants. These are also used for connecting controlling & monitoring devices & signal transmission.

Variants of Instrumentation Cables:

Instrumentation cables are available in Unshielded or shielded as well as Un-armoured & Armoured constructions. These are mostly used for fixed installations or limited flexing applications.

The shielded cables are typical with a foil shield, braid shield, or combination of the two.
These cables are mostly in Pairs or Triads. Various instrument cable types are available in the market.

Type of Insulation & Sheathing:

Best Instrument cables generally have PVC or XLPE insulation & PVC or XLPE sheathing. However, other insulating & sheathing materials are also used based on the type of application & place of installation such as TPE; PUR; LSZH; Nylon; EPR rubber; Teflon, etc

Typical Construction:

Conductor: Stranded bare copper or tinned copper of Class 2 or Class 5

Insulation: XLPE or PVC (mostly) or TPE/ Halogen-free compound

Cores laid & twisted to form pairs or Triads.

For Pairs- two cores are twisted together with short lay-lengths

For Triads- three cores are twisted together.

For Shielded Version: Aluminum Foil with Drain wire or Tinned copper braiding for EMI/EMC protection in Instrumentation Cables.

Outer Sheath: PVC/ XLPE/ POLYURETHANE/ EPR/ HALOGEN FREE COMPOUND / SILICON / TEFLON etc

Outer Sheath Colour – Black or Grey for general applications & Blue for Intrinsically Safe areas.

Typical Voltage Grades:

300/ 500 V or 600/ 1000 V

Applicable Standards:

EN 50288 (formerly BS 5308) is the widely used standards

Compliance:

RoHS/ REACH / CE
