Power Transmission Line Tower
This
category of towers are being used in Electrification projects for
transmitting the power from power generating units to substations located in
remote areas. A type of a power transmission tower depends on various
factors such as voltage (33kv to 800kv), configuration (vertical or
horizontal), line deviation angle (Suspension, Tension & Terminal, Tee off
tower).
The design of Power Transmission line tower depends on, type
of conductor and Earth-wire, wind zone, deviation angle and material
specification. These towers are galvanized to protect the steel from
corrosion. The galvanizing coating thickness depends on the weather
conditions at the location of tower.
Radio and Telecommunication Tower
This
category of towers are specially being used for wireless communication with
radio, radar, Microwaves, etc.
Antenna or radar or other wireless transmitting devices are fixed on
appropriate locations on the tower.
Substation Structures
These
structures includes Gantries and Equipment Support Structures. Gantry
structures are mainly used for guiding the power conductor from last tower
near substation to the electrical equipments in a substation. This structure
consist of a number of columns and Girder beams, which depend on number of
circuits of the line. Gantries are also used for line crossing.
Power conductors of one line can be underpassed with the help of required
number of gantries. Equipment Support Structures are columns, supporting
electric equipments in a substation.
Depending upon the site and client's requirement, the Gantry and Equipment
support structures can be mounted on substation building also.
