power transmission towers
(OP)
Can someone in the forum give me a brief description on how HV transmission towers are erected in rural areas and the equipment usually used?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

How to determine whether transposition is required or not? If it is required then at what distance and what will be the total number of transposition in the span of 300 meters.

RE: power transmission towers
I realized that what you gave was for a lower voltage. We normally use 5 or 6 disc insulators for 69 kV, and 42 feet is quite low for that voltage class. However, I was more concerned with the manner in which they are erected which I believe would be the similar. By the way, you mentioned the use of a lifter. By this, I suppose you were refering to a gin pole?
RE: power transmission towers
Assuming your alignment is fairly flat:
If you reduce your pole spacing, you can use direct embed monopole structures instead of H-frames or lattice towers. This has a lot of advantages: faster erection with smaller equipment, reduced construction cost, simpler installation (particularly when compared to lattice towers).
300 meters = 984 feet
200 meters = 656 feet
If you reduce your spacing to about 200 meters, then direct embed monopoles are feasible.
