INSTRUMENTATION CABLE

Instrumentation cables are designed for Transmission of Analog & Digital signals in instruments and Control Systems. Laser make instrumentation cables are designed to maintain high level of accuracy and sensitivity of the system without drop in signal. It is designed to obtain Maximum rejection of Electromagnetic noise, minimal cross-talk and minimal Electromagnetically or Electromanetically induced noise & common mode interference.

Individual pairs or Triads are Colour coded for simplified identification & hook-up. rugged armoured versions are recommended for use in Intrinsically Safe Systems.

The Aluminium Myler Tape screening ensures exact data and pulse transmission, protecting the cable against electromagnetic disturbances and interferences.

Fire performance options are Designed to resist and withstand extreme fire conditions, with minimal emission of Toxic gases.

Lead sheath provides excellent resistant to chemical, oil, gas & radial water blocking.

Characteristics :

  • Signal protection between pairs.
  • Good electromagnetic protection from external influences.
  • Excellent Electrical, Thermal & Physical properties.
  • Flame Retardant, Fire Retardant & Fire resistant – Highly recommended in areas with high explosion & Fire risks.
  • Lead sheath provides radial water tightness and resistance to chemicals & hydrocarbons.
  • Excellent mechanical protection during laying, installation & service.
  • Extra pulling force.
  • Option class-5 conductor provides extra flexibility.

Application :

  • Generally used for transmission of signals in control systems.
  • Typical applications include audio, intercom, control, energy measurements, alarm circuits.
  • Suitable for use in wet and dry locations.
  • Armoured cables are recommended for Outdoor & Direct Burial.
  • Unarmoured cables are recommended for indoor use.
