Temporary Transmission Towers for Maintenance & Live Line Bypass
Keep critical transmission lines in service during maintenance, reconductoring and upgrades with HTSE’s IEEE 1070 & IEC certified Temporary Transmission Towers. We engineer, transport, erect and remove the complete ERS Tower bypass, minimizing downtime while keeping power flowing.
Temporary Transmission Towers That Keep Critical Lines Energised
HTSE provides Temporary Transmission Towers for maintenance, reconductoring and transmission line upgrades. Our IEEE 1070-certified Temporary Bypass Transmission Tower creates a live bypass that allows work on the permanent structure while electricity continues to flow. The modular aluminium-alloy ERS Tower is rapidly deployed without civil foundations or heavy lifting equipment, reducing planned outages, protecting revenue and maintaining grid reliability.
After the upgrade is complete, we dismantle the ERS Tower and restore the route, giving you a faster, safer and more cost-effective maintenance solution.
Applications of Temporary Transmission Towers for Live Grid Maintenance
HTSE provides Temporary Transmission Towers and ERS Tower solutions for planned maintenance, reconductoring, tower replacement, voltage uprating and temporary line diversions, keeping critical transmission corridors energised throughout the project.
Reconductoring Projects
Challenge
Old lines are reconducted to carry more load but the shutdown that needs can run into days and a critical corridor can't spare it.How HTSE responds
A temporary bypass carries the load while the existing conductor is re-strung, so the line keeps supplying customers and the upgrade stays on schedule.
Tower Replacement
Challenge
An ageing or damaged tower has to come out and a new one go in, on a route that is still energised and earning.How HTSE responds
ERS towers bypass the structure being replaced so crews dismantle and rebuild it while power flows over the temporary line beside it.
Voltage Uprating
Challenge
Raising a line to a higher voltage class needs greater clearance and often taller towers, which means working on a live route.How HTSE responds
A temporary bypass holds the line while towers are raised or modified for the new voltage, so a 220 kV corridor can move toward 400 kV without a prolonged shutdown.
Line Diversion & Bypass
Challenge
A crossing project, a new alignment or a right of way change means a live line has to be moved or diverted.How HTSE responds
ERS towers create a temporary diversion that carries the load along a new path while the permanent line is re-routed or rebuilt.
A 10-day shutdown, cut to a few hours.
A 132 kV line in Ghaziabad was being reconducted from ACSR Panther to a higher capacity conductor, work that would normally need a 10 day shutdown. HTSE bypassed the line onto three ERS towers so it stayed energised and the required outage dropped to a few hours. The bypass ran through a crowded market and held through a hailstorm without damage.
Our ERS solutions for planned maintenance
From planned upgrades to emergency recovery, HTSE ERS towers keep power flowing while permanent structures are worked on.

Frequently Asked Questions
Temporary Transmission Towers can reduce planned outages from days to just a few hours. By deploying a Temporary Bypass Transmission Tower, HTSE keeps the transmission line energised while maintenance, reconductoring or tower replacement is completed, significantly reducing downtime and outage costs.
Yes, HTSE plans every Temporary Transmission Tower deployment in advance, including site survey, engineering and mobilisation. The system is installed within your scheduled outage window, allowing maintenance work to begin on time with minimal disruption.
In most cases, yes. HTSE sizes the temporary transmission support to your line’s rating, so the corridor keeps carrying its normal load during the works. Where a specific span or clearance calls for it, we tell you any limit up front and design the bypass around your peak demand.
The ERS is erected beside the tower being replaced and the line is transferred onto it, so the permanent structure is fully de-loaded. Your crews then dismantle the old tower and build the new one while power flows over the ERS. Once the replacement is strung and tested, the line moves back and the ERS comes down.
Yes. When a corridor is uprated to a higher voltage, the towers usually need to be raised or rebuilt for extra clearance. A temporary bypass keeps the existing line live while that work happens, so the uprating proceeds without a long outage and the upgraded line is commissioned on schedule.
The earlier the better, ideally once the maintenance is scoped. Early engagement lets us design the ERS to your exact span, soil and clearance, confirm the configuration, and have the towers ready for your window. For urgent work we still move fast, but planned lead time gets you the tightest outage and the lowest cost.
