Monopole

Traditionally overhead transmission lines are built on lattice type structures. Significant ROW and aesthetics issues have stalled construction of new transmission line corridors.Replacement of traditional lattice structures with MONOPOLE structures is a significant step in this direction. The advantages of monopoles are significant wind loading capacity, smallest footprint, higher reliability under extreme condition.
