Power Transmission & Substation Structures

Our power infrastructure range covers the full spectrum from 33kV to 765kV — substation structures, transmission line towers, and distribution structures. We are an approved vendor for WBSEDCL, WBSETCL, OPTCL, BSPTCL, NBPDCL, SBPDCL, and numerous other State Electricity Boards and engineering companies including L&T, ABB, Siemens, Alstom T&D, and Polycab.

All power structures are engineered for longevity in harsh outdoor environments. Our hot-dip galvanizing provides decades of corrosion protection, significantly reducing maintenance costs over the structure's lifetime.

Power Structure FAQ

Frequently Asked Questions

What voltage classes does Indo East build substation and transmission structures for?

33 kV, 66 kV, 110 kV, 220 kV, 400 kV and 765 kV - covering substation structures, transmission line towers and 11 kV / 33 kV distribution structures.

Which substation structure types are manufactured?

Bus posts, gantries, deadend structures, lightning masts and equipment support frames for 33 kV to 765 kV switchyards, plus feeder pillars.

Which transmission tower types do you fabricate?

Suspension, tension, deadend and transposition towers for EHV lines, fabricated to the utility's or EPC contractor's approved drawings.

What material and galvanizing specification are power structures built to?

IS 2062 Grades A, B and C, IS 8500 high-strength steel, and IS 1239 pipes. Hot-dip galvanizing is to IS 2629 / IS 4759 with a coating of 85+ microns.

Does Indo East supply polymer insulators and pole line hardware?

Yes. Composite polymer insulators, pole line hardware and fittings are part of the power range and are supplied alongside our substation, transmission and distribution structures, so a utility or EPC buyer can source the structure and its hardware from one vendor. Voltage class, creepage and mechanical rating are quoted against the customer's specification.

Which utilities has Indo East been approved by?

Approved vendor for WBSEDCL, WBSETCL, OPTCL, BSPTCL, NBPDCL and SBPDCL among other State Electricity Boards, and for engineering companies including L&T, ABB, Siemens, Alstom T&D and Polycab.

Which design standards are followed?

CEA, IS, IEC and BS standards, or the customer's own specification where one is issued.

Is galvanizing carried out in-house?

Yes. Fabrication and hot-dip galvanizing happen on the same Howrah site, in a 7-metre kettle (7 m x 1.2 m x 1.6 m). Nothing is sent out for coating.

Do you accept third-party inspection?

Yes. Power structures are routinely supplied against third-party inspection to utility specifications.
