Tangent tower
Electric Transmission Towers is a tall structure, usually a steel lattice tower used to support an overhead power line. We conduct detailed line surveys, line diagrams, tower locations, diagram structures and technical documentation before supplying these products.
The tangent tower are used where the transmission line have straight run. The tangent towers uses suspension type silicon rubber insulator which only only hold up the conductors in downward direction. These Insulator are in Vertical direction.
