DETERMINING FIELD USE BY OPENING THE CALCULATION
OF THE WIND „aV” A CONCRETE POLES FOR 110 kV LEA
ACCORDING TO THE NORMS IN FORCE
Aerial electric lines are designed to ensure safe transport and
distribution of electricity. Physical support is provided by the power lines poles.
Pillars supporting 110kV aerial lines are usually made using prestressed spun
concrete. Currently in Romania, prestressed concrete poles for high voltage
electric lines are no longer manufactured, but this type of poles are in service.
In case of intervention on a transmission line by modifying the original design
characteristics, it is important that pillars can be verified easily as area of use
for the evaluation of investment costs, to ensure in designed version the ability
to take over the loads satisfying toughness requirements and stability.
