INSTRUMENTATION CABLES

Instrumentation Cables are specially designed to transmit signals without any external interference. They are used in Data Acquisition Systems, connections to Instruments, Computer Networking, PASystems, Digital / Analog Control / Measuring & Communication Systems.

  • Construction : Cores, pairs, triads or quads
  • Voltage Grade : Up to 1100 V
  • Conductor: Electrolytic grade copper Bare / Tinned Solid / Stranded/Flexible conductors
  • Range : 0.5 / 0.75 /1.0 /1.5 / 2.5 Sq mm up to 48 Pair
  • Primary Insulation: General purpose PVC / Heat Resistant PVC / LDPE / XLPE / PTFE / Fibre Glass/ FEP / Silicone Rubber
  • Screening : Individual and/or overall with following options –
    – Aluminum Mylar/CopperTape with Tinned Copper Drain Wire or
    – Braided with Bare or Tinned or Nickel Plated or Silver Plated Copper
  • Inner Sheath : PVC / HRPVC / FRPVC / FRLS PVC / ZHFR / LSF
  • Armouring : Gl round Wire / Flat strip or Wire Braiding
  • Outer Sheath : PVC / HRPVC / FRPVC / FRLS PVC / ZHFR / LSF
  • Rip Cord : For easy removal of sheath
  • Standards : BS-5308 Part-1 & 2, BS-7655, IEC-189 (1 & 2), VDE-0815 & 0816 and BS EN 50288
