Mar 02, 2017 · Comparison of Various Bracing System for Self-Supporting Steel Lattice Structure Towers. In Table 2, the maximum resultant moment occurred at the bracing type KX, which was 7990.115 kN.m and 8035.038 kN.m for linear, and nonlinear analysis respectively.
So the towers can be categorized as small angle, medium angle or large angle towers. The towers used at the termination point of line are dead end towers and are designed to carry large unbalanced load. The dead end towers are the strongest and heavy. In practice large angle towers are designed so that they can be used as dead end towers. Doing so will eliminate the need for designing one more tower type

The standard commonly used structural steels are: Carbon steels. A36 - structural shapes and plate. A53 - structural pipe and tubing. A500 - structural pipe and tubing. A501 - structural pipe and tubing.
There are different types of towers use for electrical power transmission lines. The major types of Transmission towers can categorize as bellow. 1. Suspension Tower 2. Tension Tower 3. Transposition Tower 4. Special Tower. Following are the types of transmission tower types which are widely used by considering the technical background.
TOWER TYPES AND STRENGTH CAPACITY Tower types. Basic purpose: suspension line towers in the transmission line route: NAH2, NAL2, NAP2 tension: ZAE2, ZAH2, ZAJ2, ZAL2, ZAM2 The order of towers corresponds to the tower weight order and their implementation from lighter conditions towards the heavier load on the transmission line route. Some results are removed in response to a notice of local law requirement. For more information, please see here.
Steel Connections -Dr. Seshu Adluri Beam to Column Rigid Joints Stiffener plates are used to shore up the column flanges against the forces transmitted by the beam flanges. The stiffeners may be full length or may extend only part of the column web depth.

Therefore, functional requirements are understood here as the electrical requirements which guide the tower design after establishment of the basic specifications. The tower designer should be familiar with the main features of the different types of insulators. In Figure 3 three types of insulators are shown.
Definition: The different types of structure (poles or towers) used for supporting the overhead lines or wires, such types of structures are called line supports. The line support plays a major role in power transmission. It kept the proper spacing between the conductors and maintained the conductor at the prescribed distance from its ground parts. Some results are removed in response to a notice of local law requirement. For more information, please see here.
