Transmission Towers

Neueon Towers Limited (NTL) has been upgrading its technology to offer better and higher quality transmission towers. Our dynamic business strategies help in the growth and development of the domestic power sector.

In the recent times, India has started upgrading its grid capabilities under the aegis of PGCIL (Power Grid Corporation of India) from the existing 132 / 220 kV to 400 / 765 kV to bring the country’s power transmission system at par with other nations.

The plans are on anvil to create a national back bone with transmission capability of 1200 kV in the next five year plan. This has resulted in a very bright business opportunity for Neueon Towers as the demand for its products has witnessed a huge surge.

Tower specifications:
NTL offers complete support on Engineering, Construction and Procurement services for power towers. The towers support the conductors and provide physical and electrical isolation for energized lines. The minimum set of specifications for towers are the material of construction, type or geometry, span between towers, weight, number of circuits, and circuit configuration.

At 500 kV, the material of construction is generally steel, though aluminum and hybrid construction, which uses both steel and aluminum, have also been used. The type of tower refers to basic tower geometry. The options are lattice, pole (or monopole), H-frame, guyed-V, or guyed-Y.

The span is commonly expressed in the average number of towers per mile. This value ranges from four to six towers per mile. The weight of the tower varies substantially with height, duty (straight run or corner, river crossing, etc.), material, number of circuits, and geometry.

The average weight of 670 towers for 500-kV lines included is 28,000 lb. The range of reported tower weights is 8,500 to 235,000 lb. The type of tower (specific tower geometry) is very site-dependent, and, for any given conditions, multiple options are likely to exist.

The number of circuits is generally either one or two. The circuit configuration refers to the relative positioning of conductors for each of the phases. Generally, the options are horizontal, vertical, or triangular. The vertical orientation allows for a more compact ROW, but it requires a taller tower.
