Steel Tube Pole Electric Tapered Tubular Monopole Tower
It is single self-supporting pole, widely used in power transmission line or telecom project. Based on the number of segments, this monopole towers are classified as four slope tower, Three slope tower; Two slope tower; Single slope tower; Straight tower.
In telecom project, four slope monopole towers is generally placed over roofs of high raised buildings, when number of antennae required is less or height of tower required is less than 9 m. In power transmission line project, four slope monopole towers is widely used in city grid corporation for 10KV, 35KV, 66KV, 69KV, 110KV, 115KV, 220KV power transmission line project.
