03Transmission Line Inspection

Complete tower inspection, without ever sending a team to climb — even on live lines.

We use drone-based inspection to perform a complete scan of transmission towers up to 765kV — capturing structural, thermal, and component-level detail safely from the air, without requiring a line shutdown.

Proven at Scale

What We Check

Every critical component on the tower — not just a broad structural pass.

11

Categories checked

01

Insulator Strings

Cracks, flashovers, and surface contamination.

02

Arcing Horns

Damage and misalignment.

03

Jumpers & GW Jumpers

Connection integrity and overheating at jumpers and ground-wire jumpers.

04

Corona Control Rings

Damage or displacement.

05

Strain Clamps

Looseness and wear.

06

Vibration Dampers

Missing or damaged units.

07

Spacers

Condition and positioning.

08

Cross Arms

Structural integrity and corrosion.

09

Tower Body / Cage

Overall structural condition.

10

Foundation & Legs

Corrosion, cracks, and erosion.

11

Earthing, Signage & Fencing

Earthing wire continuity, plus anti-climb fencing, danger signs, and name boards — presence and condition.

Good to know

Plus thermal scanning across all joints and connectors to catch overheating before it causes failure.

How We Work

A structured process — from first flight to final report.

04

Steps

1Step 01

Route & Tower Mapping

We map out every tower along the line to be inspected and plan drone flight paths for complete coverage of each structure.

2Step 02

Live-Line Aerial Data Capture

Our DGCA-certified pilots fly around each tower — even on energised lines — capturing high-resolution thermal and visual imagery from multiple angles, with no need for a shutdown or outage.

3Step 03

Data Processing & Analysis

Captured data is processed to detect and classify anomalies — thermal and structural — each tagged with severity and exact tower and component location.

4Step 04

Reporting

You receive a structured, tower-wise report with geo-tagged findings, prioritized by severity. All data is also available on our web-based analytics portal, where you can view each tower's thermal images directly, check exact temperature readings, and review defect locations anytime.

Built for Every Team on Your Project

One inspection — value for every stakeholder on site.

Teams served

01

For Utility Owners & Asset Managers

Get complete tower-level visibility without the time, cost, and risk of manual tower climbing — plan maintenance based on real data.

02

For O&M & Maintenance Teams

Get exact defect locations on every tower and component, so field teams can go straight to the problem instead of inspecting structures manually one by one.

03

For EPCs

Verify tower condition before handover and catch construction-stage defects early — avoiding disputes after commissioning.
