Advantages of Lattice Towers
Design and detailing



The capacity of latticed tower members and
connections can be described by relatively simple
formulae.
Modeling and design is relatively easy.
Deflection of guyed lattices towers will be much
higher as compared to self supported towers and
monopoles.
The dynamic overall behaviour of lattice towers is
ideal for wind turbines.
The configuration of latticed towers can be easily
adjusted to accommodate several electric circuits
and various types of conductor configurations.
Advantages of Lattice Towers
Tower cost and Fabrication





Monopoles are generally more costly than lattice angle
towers due to higher cost of plates
Monopole requires specialized plate bending machine
with high capital cost.
Lattice towers using angle sections are very easy to
fabricate with quick factory setup.
The thickness of monopole plate increases rapidly with
tower height and loads.
Galvanization of monopole sections are much difficult
than angle sections.
Transportation


Lattice angle sections can be bundled as per available
capacity of trucks and hence easy to transport.
Sizes and weights of tower members to be transported
are less when compared with tubular steel poles.
Advantages of Lattice Towers
Erection


Extremely flexible scheduling on a building site,
with many jobs of work performed parallel.
Erection of lattice towers can be carried out using
gin poles or floating derricks where crane
erection is not possible.
Ecological


The lattice structure is highly transparent so that
it has a lesser effect on the landscape.
Optimum ecological balance thanks to the
galvanized steel structure and small concrete
foundations (savings in terms of raw materials;
both tower and foundations can be recycled).
