The exact type of tower structures that will be used for this Project has not been selected at 
the time of writing the ESIA. However preliminary details are described below.
It is anticipated that the transmission line will consist of a large number of towers/pylons that 
will be self-supporting and grounded to ensure low resistance. At this stage it is anticipated 
that the type of towers could be either:
 
Suspension towers - used for straight section of the line to keep the wires off the 
ground or; 
 
Angle angular (tension) towers 
– used to tension the wires and accommodate 
changes in direction of the line 
The selected tower types will be designed to meet the applicable Uzbekistan standards & 
regulations and will be stell lattice design. All metal structures will be galvanized. Given an 
overall buffer corridor of 30m, safety distance from the centre line of the transmission line will 
be 30m in accordance with Uzbekistan requirements.

The foundation for the towers will be constructed using concrete and reinforcement. The 
concrete used will be suitable to the specific carrying capacity of the different terrain along 
the OHTL route. The type and size of the foundation will be dependent on the outcome of the 
geotechnical investigations undertaken along the OHTL route.
Typical foundation dimension for a 500kV tower is presented in the figure below.
