In cases where the use of lines with bare conductors may result in transient accidents or when compliance with privacy and other technical and safety considerations of the power grid is not possible, the use of self-contained air cables is a reasonable solution. The most common of these are paths that are low in width or where there are obstacles such as trees.

Self-supporting cables have insulated conductors and are used for voltage levels of 1 to 36 kV. An insulated filament called Messenger is used to install such cables, which can withstand the total weight of the cable. In the low pressure self-supporting cable, the retaining wire will also be used as a null wire.

Iran Cable Manufacturing Company manufactures various types of self-supporting cables from two to six strands with aluminum conductor and XLPE insulation according to international standards. Meet the operational and operational requirements....

    Advantages of using self-supporting cables

  • Can be used in narrow and highways
  • Reduce the probability of short-circuiting the phases with each other
  • Excessive voltages caused by lightning do not cause defects in the metering meters of the subscribers.
  • Protect the environment by cutting down trees and cutting down trees
  • Reduce the likelihood of fires in highland areas
  • Prevent unauthorized use of electricity
  • No power outages due to cable or animal contact with the cable causing short circuit.
  • Reduce conductor theft in power distribution lines
  • Reduce line maintenance costs
  • Better price than lines with bare copper conductor
  • Reduce corrosion of conductors due to weather conditions
