CHARACTERISTICS OF ELECTRICAL LINES POLES LV-MV
 
THE ADVANTAGES.
 
NO MAINTENANCE
The users prefer the concrete poles owing to the absence of corrosion and maintenance
which are specific of the steel poles.
 
SECURITY
  •   No cracks owing to the use of the prestressing, thus preventing the corrosion of
  •     steel bars which sometimes occurs in reinforced concrete poles.
  •   No failure: the yield strength is 2,1 times the nominal strength.
  •  
    FATIGUE RESISTANCE
    The tests show that the prestressed concrete poles can endure at least twice more alternate strengths than the reinforced concrete ones, thanks to the absence of cracks.
     
    QUALITY OF THE MATERIALS
    The prestressing demands the top quality of the high tensile steel and of the concrete, which is the best guarantee.
    Any wrong material is rejected by the factory.
     
    LIGHTNESS
    The prestressing allows to reduce the weight of the poles by 25 to 30% when compared to the reinforced concrete ones.
     
    CUTTING THE COST
    Low cost of production:
  •   Domestic manufacturing and use of the local materials (cement, agregates...)
  •   High cut of steel needs which means savings of foreign currencies.

  • No maintenance.
