there are two types of towers mainly.
1.self supporting towers 2.stayed or guyed towers
self supporting towers mainly devided into (a)wide base
&(b)narrow base.
foundation cost of the narrow base towers are greater than
wide base towers.
this is also devided into-
.tangent type towers(suspension insulator used in this type
tower)
.deviation type towers(tension type insulator used in this
type tower)
2.stayed type towers classifide into two type (a)portal type
&(b)v type (it redused weight & cost)
