Tower Classification and Installation
This is the first paper of the series of articles of transmission lines. From this series we are going to give you the basics of transmission lines, practical site situations and also highly mathematical level that required in bachelors level and masters level.
Team “Newsican”, changing the strategy instead of the most exclusive news and more usable and useful knowledge that we can provide in the education background. So this is the first paper in electrical engineering and we decided to start in the middle of the Electrical Engineering it is because our expertise in lay on this area in present days.
So what is a transmission line,
Transmission line used to transmit electrical power from one place to another place or from generating stations to load centers. Transmission lines used to transmit power in very high voltages and it is become interesting and also risky work, that highly knowledgeable people can handle the operation.
Classification of Transmission Lines
Short Transmission Lines – These are bellow 50 km and Voltage bellow 20kV
Medium Transmission Lines – These are above 50km and bellow 150 km and Voltage above 20kV
Long Transmission Lines – These are above 150km and the voltage above 100kV
In the practice method the transmission lines are classified according the method of construction. Meaning the general method of the tower construction.
- Single Circuit Transmission Lines
- Double Circuit Transmission Lines
And also the tower design of the transmission line classified as the angle of the transmission line in the pivoted position of the tower center. Because of the angle difference makes lots of mechanical differences the cost for build the different angle position tower will have a huge difference.
TDL – Tower Double circuit Circuit Line (Angle 0 Degrees)
TDM – Tower Double Circuit Medium (Angle 0-30degrees)
TDH – Tower Double Circuit Heavy (Angle 30 – 60 degrees)
TDT – Tower Double Circuit terminal (At the end of line)
TSL – Tower Single Circuit circuit line (Angle 0-30degrees)
TSM – Tower Single Circuit Medium (Angle 0-30degrees)
TSH – Tower Single Circuit Heavy (Angle 0-30degrees)
TST – Tower Single Circuit terminal (At the end of line)
Transmission Line Project - Southern Province - Western Province
In Practice the transmission line projects it is required to follow up a preliminary survey, to find the best route for the transmission line from the given target position, while doing so the soil test need to be carried out for the planned positions to identify how the withstand strength of soil for the tower. If the soil is not in god condition there should be some soil treatments need to be done and also the tower basement need to be change as per the requirement. Now this is a great place that civil engineering , mechanical engineering, and also electrical engineering getting in the same place and thinking for options.
Basement Classification of transmission towers.
Type A Concrete block – good soil
Type B Concrete block – poor soil
Type C Concrete block – waterlogged
Type D Raft type
Type E Well type
Type F Soft rock
Type G Hard rock
Type H Pile Foundation
Practical situations always have exceptions and all our followers readers are welcome to encourage us with there practice and new ways of improvements, to share knowledge with everyone.
So comment section is always open for our guests.
