A lattice tower or truss tower is a freestanding vertical framework
tower. This construction is widely used in transmission towers
carrying high voltage electric power lines. Its advantage is good
shear strength at a much lower weight than a tower of solid
construction would have as well as lower wind resistance. In
structural engineering the term lattice tower is used for a
freestanding structure, while a lattice mast is a guyed mast
supported by guy lines.
A lattice transmission tower is a key part of a power transmission
system. A lattice transmission tower consists of the following
parts:
- The peak of the transmission tower
- The cross arm of the transmission tower
- The boom of transmission tower
- Cage of transmission tower
- Transmission Tower Body
- Leg of transmission tower
- Stub/Anchor Bolt and Baseplate assembly of the transmission tower.
