What and Whys of Instrumentation Cables

Instrumentation cables are a necessary mechanical and electrical component in production, heating or melting purposes in factories and production units. Here the basic circuit design of the cables is what needs attention. This is not an easy task and must be done by a trained and technical staff from the premium instrumentation cable exporters only. The installation of the right kind of cables is important to ensure a smooth and error free operation, and in order to exercise regulation and control over the circuit movements. Hence it is advisable to seek the necessary guidance from the leading and best ofinstrumentation cable exporters who will provide the genuine products which are quality assured and tested as per quality norms and standards.

Types There are 2 types of Instrumentation cables:

  • Type 1 – These type of instrumentation cables are either PE insulated and PVC sheathed or PVC insulated and PVC sheathed.
  • Type 2 – These instrumentation cables are either:
  1. PE insulated and PE bedded, single wire armour and PVC over sheathed
  2. PVC insulated and PVC bedded, single wire armour and PVC over sheathed

Features The features which make an instrumentation cable most preferred are as below:

  • Conductivity – The conductors in an instrumentation cable needs to be a plain copper wire which is either Class 1 or solid, Class 2 or stranded and flexible or Class 5.
  • Insulation – The instrumentation cables are insulated with any of the below:
  1. PVC ( Polyvinyl chloride)
  2. PE ( Polyethylene )
  3. XLPE ( Cross linked polyethylene )
  4. EPR ( ethylene propylene rubber )
  • Screening – Two insulated conductors are twisted to form pairs which are clustered and assembled and these pared conductors can be either unscreened, individually and totally screened respectively or completely screened for both. The screening materials is generally aluminium tape, copper tape or made from a copper wire braiding as per the application area and customer requirement.
  • Armouring – The armouring in an instrumentation cable serves to protect the cable in mechanical terms. However an instrumentation cable can be armoured or non-armoured, consult the renowned exporters to suggest which one is apt for your project. The armour is generally of a galvanized steel wire, a tape or any braiding wire..
  • Sheathing – While the armour protects the instrumentation cables from mechanical damage of pressure or breakage, sheathing protects the critically functioning cables from moisture, abrasion and chemical reaction to the surrounding materials. Hence the sheathing component needs to be chosen and customised carefully. Here also, it is the trained technical staff who can guide you on the exact type of sheathing that is required for the instrumentation cable based on the surrounding conditions. The common types of sheathing materials are as below:
  1. PVC ( Polyvinyl chloride)
  2. LSOH ( Low Smoke Halogen free )
  3. PE ( Polyethylene )
  4. EVA ( Ethylene Vinyl Acrylate )
  5. EMA (Ethylene Methyl Acrylate )

Applications Instrumentation cables are designed for usage in communication and instrumentation applications in and in industries like oil exploration, cement, paper, steel, power generation, process controls, transmission of signals, computers, control systems and monitor networks, hazardous substances like petrochemical plants and thermal power plants etc.
