what are the various types of towers used in transmission
line
Answer Posted / tarun aggarwal ymca
According to different considerations, there are different types of transmission towers. The transmission line goes as per available corridors. Due to unavailability of shortest distance straight corridor transmission line has to deviate from its straight way when obstruction comes. In total length of a long transmission line there may be several deviation points. According to the angle of deviation there are four types of transmission tower
1. A – type tower – angle of deviation 0o to 2o.
2. B – type tower – angle of deviation 2o to 15o.
3. C – type tower – angle of deviation 15o to 30o.
4. D – type tower – angle of deviation 30o to 60o.
As per the force applied by the conductor on the cross arms, the transmission towers can be categorized in another way.
1. Tangent Suspension tower and it is generally A - type tower.
2. Angle tower or tension tower or sometime it is called section tower. All B, C and D types of transmission towers come under this category.
Apart from the above customized type of tower, the tower is designed to meet special usages listed below,
These are called special type tower
1. River Crossing Tower
2. Railway/ Highway Crossing tower
3. Transposition tower Based on numbers of circuits carried by a transmission tower, it can be classisfied as
1. Single Circuit tower
2. Double Circuit tower
3. Multi Circuit tower.
