Control cables are exclusively deigned for automation controls. They come with a copper conductor which is enveloped in a steel braid.These are a type of instrumentation cables which send signals to control the functioning of equipment, and are responsible for distribution of low voltage data or signals. The cables have PVC insulation that protect them from the impact of harsh weather conditions. Like Power cables, there are various types of Control cables specifically designed to suit various automation and computer applications. Twisted in pairs, the Control cables possess a balanced shielding, that reduces interference. Often enveloped in a white external jacket, these cables have their specifications written in black, which provide excellent visibility. These are positioned between power cables and communication cables.

Before choosing any copper control cable for your uses, make sure you keep these points in mind:

  1. The Control Cable need to conform in all respects to high standard of Engineering design workmanship and latest revision of relevant standards.
  2. The wires need to conform with the following standards:
IS: 1554 (Part-1): Specification for PVC insulated (heavy duty) electric cables for working voltages up to and including 1100 volts.
IS: 5831: Specification for PVC insulation and sheath of electric cables.
IS: 8130: Specification for conductors for insulated electric cables and flexible cords.
  1. The cables needs to  be suitable for laying in covered/open trenches, ducts, trays or buried directly underground under dry or damp conditions
  2. Suitable additives to avert attack by rodents, termites shall be added to the outer sheath PVC compound.
  3. The conductors need to be circular and stranded.
  4. They shall be dirt-free, reasonably uniform in size and shape, smooth and free from all destructive defects.
  5. The insulation for this cable needs to be “General Purpose Insulation” of Type-A PVC Compound, suitable for a maximum rated conductor temperature of 70 deg C intended for cables with rated voltages up to and including 3.3 kV.
