Transmission Towers

Skipper Limited is the largest Transmission Tower manufacturing company in India and also among the top 10 largest tower manufacturers  in the world. Skipper's strong focus and commitment towards product quality has made it the manufacturing partner of choice to Powergrid Corporation of India (PGCIL) - the world's largest transmission utility and also Ramboll - world's largest tower design company.

Here are just some of the many strengths and advantages of Skipper's Tower manufacturing Division :

  • Among the best Capacity Utilization (consistently 90% for several years) in the Industry
  • In-House Design & Engineering department helps reduce the project cost for our customers through optimized Tower designs and also ensure the accuracy of structure fitment so that site rectifications are eliminated.
  • Almost 75% Production is through Automated CNC lines
  • 7 Galvanizing plants in-house with a Galvanizing capacity of over 200,000 MT per year
  • Entire Manufacturing process and Inventory control through Automated ERP solution
  • Presence of In-house Rolling Mills ensure greater output with lesser inventory requirements
  • 100% Material Traceability from Billets to Finished Towers. We use 100% Tested Billets from Main Steel Plants only.
  • Strong Quality Assurance and Modern Testing Laboratories - One of the few manufacturing companies to boast of NABL certification for it's in-house test labs
  • Best in the Industry Packing & Bunding process using Wire Weaving and Metal Strapping to ensure Faster Inventory reconciliation and zero shortage of material at sites
  • Additional Lashing & Choking Packing process for Export containers

At Skipper Limited, Transmission towers are not viewed as a product, but as a service. From designing and assembling each component to the delivery of a customized product, Skipper is present along the entire value chain.

Product Specifications

At Skipper Limited, we offer our customers a full-range-cum-diverse product basket ranging from 66 KV to 800 KV Towers (Single Circuit, Double Circuit, Multi-Circuit Towers suitable for Twin, Triple, Quad or Hex Conductor configurations). We can offer Tower materials as per Indian as well as International material grades ranging from BSEN to ASTM to GOST.

Guyed Towers

Guyed structures have become the dominant type for use on transmission lines remote from urban areas or where land use restrictions are prohibitive. All other attributes, including cost of materials, erection and performance are positive and the continuing pace of innovations of types and techniques is adding to their attractions.

Guyed towers feature simple tower type, easy construction, and smaller weight of single tower which can reduce steel consumption and construction costs, and they are mostly used in areas where operation and maintenance are convenient, such as shallow hills and deserts. V-Guyed tower refer to lattice tower which supported and fixed by stay wire, and from one 'V'shape. These may have, for each conductor, an insulator string hanging down from the tower, or two strings making a "V" shap.

So why a guyed tower?

Guyed structures offer rigid support for technical equipment by providing minimal deflection. Taught guys transfer bending and twisting loads into vertical or axial loads culminating in a point load at the base. Due to this design feature, freestanding towers should never be guyed. Although you might be able to get away with it, it is a less than ideal engineering practice as converting a bending moment to a vertical load could cause failure. Adding guys to strengthen a structure might just have the opposite effect.

Although guyed towers have a larger footprint, it can provide significant cost savings where space and topography are not an issue. Less engineering, material, and fabrication is required when compared to a freestanding design. For the foundation, the low bending moment and high vertical load can greatly reduce civil work at the base. Although a guyed tower requires many foundations (the base plus one for each guy anchor), they are smaller and can be done without the use of heavy machinery. This is critical for remote locations where access can be an issue.
