To support local partners in expanding powerline inspection and grid operation services in Malaysia, GreenValley International recently demonstrated its complete LiAir X4 + LiPowerline powerline inspection solution.
Combining autonomous flight, high-precision LiDAR data acquisition, intelligent point cloud analysis, hazard detection, and refined flight route planning, the solution provides a reliable workflow for modern transmission line inspection and maintenance.

Autonomous Transmission Line Following with LiAir X4
During the field demonstration, LiAir X4 performed autonomous transmission line following for efficient corridor data acquisition.
The system supports adjustable line-following speeds from 2–10 m/s. In this demonstration, the UAV operated at 8 m/s while maintaining a flight altitude of 20 m above the ground wire, allowing the system to accurately follow the transmission corridor trajectory.
Before the mission begins, operators can predefine the inspection tower range. After data acquisition is completed, the UAV automatically performs Return-to-Home (RTH), reducing manual intervention and improving operational efficiency in large-scale inspection scenarios.



Intelligent Point Cloud Classification
The collected LiDAR data was processed and automatically classified in LiPowerline to reconstruct the transmission corridor and tower structures in detail.
The system accurately identified and classified key elements including:
Ground points
Medium vegetation
Conductors
Shield wires
Tower structures
Insulators
The structured classification results provide reliable data support for vegetation analysis, hazard detection, asset management, and inspection planning.


Intelligent Vegetation Risk Detection
Based on the classified point cloud data, the system automatically detected vegetation risks and calculated clearance distances between conductors and surrounding vegetation.
During the demonstration, the minimum detected clearance distance was 12.169 m, enabling rapid identification of potential risk locations along the transmission corridor.
The workflow also supports customized inspection report generation based on local utility operation and maintenance standards, helping inspection teams generate standardized and practical deliverables for vegetation management and grid safety assessment.


Refined Inspection Route Planning with LiPowerline
LiPowerline includes a built-in library of standard tower types and supports intelligent extraction of key inspection components, including:
Insulators
Suspension points
Jumper wires
Other critical transmission line components
After extracting key component points, the system can automatically generate refined inspection flight routes with a single click.
The workflow also supports:
Automatic flight route safety optimization
Customizable waypoint parameters
Multiple route export formats
Compatibility with various UAV platforms
This enables detailed tower inspection and comprehensive coverage of critical transmission line assets.





A Complete Workflow for Smarter Powerline Inspection
The Malaysia field demonstration highlighted the practical effectiveness of the LiAir X4 +LiPowerline solution across the complete powerline inspection workflow.
From autonomous transmission line following and high-density LiDAR acquisition, to intelligent classification, vegetation risk analysis, and automated inspection route generation, the solution helps utilities and inspection teams achieve:
Increased operational automation
More accurate spatial data acquisition
Faster hazard identification
More efficient inspection planning
Improved reporting and decision-making efficiency
By combining advanced LiDAR hardware with intelligent software analysis, GreenValley International provides a reliable and scalable solution for modern transmission line inspection, helping utilities and service providers improve inspection efficiency, enhance safety management, and support smarter power infrastructure maintenance.
