Engineering EPC
End-to-end HT overhead transmission line construction — tower foundation, erection, stringing, tensioning, and conductor installation for 11kV to 220kV systems, including voltage upgradation projects.
Overview
Daakshyaani executes HT overhead transmission line projects across varied terrain in Andhra Pradesh and Telangana, from 11kV rural distribution lines to 220kV dedicated lines for large industrial clients. Our longest documented line is 14km (HariyalliKissan Bazar, Krishna District). We also execute voltage upgradation projects — raising existing 11kV systems to operate at 33kV — enabling industrial clients to meet growing load requirements. Our team handles the full scope: survey, route planning, tower foundation, erection, conductor stringing, and DISCOM energisation.
Why Daakshyaani
Our contractor license in AP and Telangana authorises HT line construction without sub-licensing — full accountability on a single team.
Right of way is the most common reason transmission line projects get delayed. We handle landowner easement negotiations, government land permissions, railway authority approvals, and NHAI NOCs for NH crossings — as part of our standard EPC scope, not an extra.
Andhra Pradesh's coastal districts are classified severe cyclone hazard zones. We specify and erect structures designed for enhanced wind loads per IS 875:2015, including the cyclonic load factors required in districts along the Bay of Bengal coast.
Before a project is awarded, we advise clients on route alignment, structure selection, conductor grade, and the fastest approval path. Once awarded, we execute. This means clients get unbiased front-end engineering — not just a contractor who builds what they're handed.
We coordinate with APEPDCL, APSPDCL, APCPDCL, TGNPDCL, and TGSPDCL for 11kV/33kV lines, and with APTRANSCO and TGTRANSCO for 132kV/220kV work — procuring to each utility's conductor specs (ACSR Rabbit/Dog/Panther/Moose) and following their commissioning procedures.
Solar and wind plants in AP/TG require dedicated 33kV, 66kV, or 132kV evacuation feeders before generation can begin. We build M-type tower lines and sub-transmission feeders for renewable developers — coordinating with the Green Energy Corridor programme and state grid connections.

Raising an existing 11kV line to 33kV to carry a heavier load is usually called "voltage upgradation" in utility and contractor documentation, not "augmentation." The distinction matters when researching the process or reading a DISCOM circular — the two terms sometimes get used loosely, but upgradation is the one that shows up in official technical literature.
HT line construction follows a fixed sequence — route survey, tower foundation (pile, spread footing, or the Build Up Method for lattice towers), stub setting within tight tolerance, tower erection, then conductor stringing and tensioning. Getting stub tolerances wrong at the foundation stage cascades into misalignment problems by the time conductors are strung, which is why survey and foundation work get the most scrutiny on-site.
Most rural and industrial distribution networks in AP and Telangana run on 11kV for local loads and 132kV for bulk transmission, with 33kV sitting in between as the step-down/step-up bridge that connects the two. A line built or upgraded to 33kV is usually doing exactly that job — carrying power from a bulk transmission point down to where it can be distributed at 11kV, or aggregating industrial loads up to a level the wider grid can absorb.
Industries
PCC/RSJ poles for 11kV/33kV lines, tubular steel poles for 33kV/66kV, lattice towers for 132kV/220kV, and M-type towers for solar/wind evacuation lines.
Yes — RoW/easement coordination, NHAI NOC where lines cross highways, and forest/environmental clearance through MoEF&CC and the AP Forest Department are part of our scope, not left to the client.
A 14km 33kV line from Hariyalli to Kissan Bazar in Krishna District — one of several multi-kilometre lines we've delivered across AP and Telangana.
Yes, structural design follows IS 875:2015 wind load provisions, which is critical for coastal Andhra Pradesh routes exposed to cyclonic loading.
