Cable is defined as a group of individually insulated wires (conductors) encased together in sheathing. Sheathing is a non-conducting material with protective properties to shield the conducting part of the wire/cable

Cross sectional area of the conductor – sometimes called 'cable size' Given as mm², it describes the total cross-sectional area of the copper conductor. Cable will be sized 1 mm², 2 mm², 4 mm² etc. and may be written as 1 mm, 2mm, 4mm. This is not the diameter of the cable.

  • Low voltage cables (up to 750 V): in a variety of applications, and with thermoplastic and thermoset coatings. They are designed and built according to harmonized standards.
  • Low Voltage cables (up to 1,000 V): (also called (0,6/1 kV) The cables in this section are used for industrial power installations in various fields (general industry, public installations, infrastructures, etc.). They are designed according to international standards (UNE, IEC, BS, UL).
  • Medium Voltage cables: from 1 kV to 36 kV. They are used to distribute electricity from electrical substations to transformer stations.
  • High Voltage cables: from 36 kV. They are used to transport electricity from the generating plants to the electrical substations.

An electric cable consists of:

  • Electric conductor: which channels the flow of electricity
  • Insulation: it covers and contains the electric flow in the conductor.
  • Auxiliary elements: that protect the cable and guarantee its longevity.
  • Outer sheath: it covers all the mentioned materials protecting them from the outside.
