Power Cable
  • Used for higher voltage transmission
  • Typically up to 400 A and 32KVAC
  • Used for energy transfer
  • Thicker and have a larger conductor size (1.5 mm – 630 mm)
  • Do not require shielding, as they do not transfer any signal
  • Used for power transmission and distribution, overhead equipment, and other high-power applications
  • Power cable mostly come in a single core
  • The sheathing is strong and sturdy and is resistant to different external factors, including corrosion and temperatures.
  • Power cables deal in high power, a large electromagnetic field is generated around the cables every time.
Instrument Cable
  • Smaller amount of voltage and current
  • Typically up to 24VDC and 20 mA
  • Used for signal transfer
  • Thinner cables (0.5 mm – 1.5 mm).
  • Require shielding, as they transfer signal
  • Used for industrial automation and other signal control applications.
  • Instrument cable is mostly a multicore cable
  • Control wires do not require the same sheathing and often have regular PVC
  • Designed to only carry low power, they do not generate any electromagnetic field and apart from this, they are also protected from noise and other electromagnetic radiation
