F15 UAV power line inspection sounds impressive on paper.

But if you work in utilities, you already know the real question:

How do you inspect power lines in mountains without burning time, people, and batteries?

I'm talking about:

• High-altitude terrain

• Wild weather shifts

• Transmission corridors that run forever

• Teams constantly stopping, swapping batteries, and restarting missions

That's the daily reality for power grid inspection.
And that's exactly what this test in Yunnan was built to deal with.

Why traditional power line inspection UAVs fall short

Let's be honest.
Most small multi-rotor power line inspection drones weren’t designed for long-distance work.

Here's what usually happens:

• You fly 3–5 km

• You land

• You swap batteries

• You move the team

• You restart the mission

Do that enough times and:

• Data continuity breaks

• Shift handovers create gaps

• Efficiency drops fast

In mountainous terrain, those problems get worse.
Steep elevation changes.
Wind tunnels.
Limited takeoff points.

That's the gap the F15 unmanned helicopter is meant to fill.

Why ZIYAN chose the F15 unmanned helicopter

Instead of forcing small drones to do big-drone work, ZIYAN took a different route.

We deployed the F15 UAV, a long-endurance electric unmanned helicopter built for range, payload, and stability.

Here’s what made the difference:

• Long-distance flight without constant stops

• Stable performance in high-altitude environments

• Enough payload capacity for serious LiDAR work

No hacks.
No workarounds.
Just the right tool for the job.

Long-distance power line inspection in real terrain

This wasn't a lab test.
It was real-world power grid inspection across Yunnan, China.

Test conditions:

• Route length: ~40 km

• Elevation range: 1,800 m to 3,200 m

• Terrain: mountainous, complex, unpredictable

The goal was simple:
Cover more ground.
Collect better data.
Reduce operational friction.

F15 UAV endurance and payload performance

This is where the numbers start to matter.

The F15 UAV delivers:

• Up to 100 minutes maximum endurance

• 5 kg payload capacity

• Over 60 minutes of effective flight time with LiDAR onboard

What that means in practice:

• 20–30 km of power line covered in a single sortie

• Fewer takeoffs and landings

• Fewer human errors

• Massive efficiency gains

Compared to traditional multi-rotor UAV inspection, this changes the workflow completely.

Built for wind, altitude, and bad days

High-altitude UAV operations aren’t forgiving.

The F15 was engineered with:

• Multi-redundant flight control

• High-resilience propulsion

• Stable attitude control above 3,000 m

Wind performance:

• Takeoff and operation in Level-7 winds

• Survivability up to Level-8 winds

That’s the difference between cancelling a mission and getting it done.

High-density LiDAR power line inspection data

Hardware only matters if the data holds up.

The LiDAR power line inspection system on the F15 delivers:

• Dense point clouds

• High-accuracy 3D imaging

• Reliable data even at higher flight speeds

This enables:

• Accurate 3D reconstruction of transmission corridors

• Faster identification of clearance risks and structural issues

• Cleaner datasets for post-processing

Less noise.
Less guesswork.
More confidence.

What the Yunnan test actually achieved

Let's get specific.

During a single flight, the F15:

• Flew over 60 minutes effectively

• Collected 42+ km of 3D corridor data

• Achieved 177 pts/m² point-cloud density

Compared with conventional multi-rotor UAVs:

• 36% improvement in data quality

• More than 4× operational efficiency

That's not incremental improvement.
That's a different category of performance.

What this means for power grid operators

This test proves something important.

Long-distance, high-altitude power line inspection UAV operations don’t need to be painful.

With the right platform:

• Fewer crews are needed

• Missions run longer and cleaner

• Data becomes more reliable

That's how inspection teams move from manual-heavy workflows to data-driven, intelligent power grid inspection.

Where this goes next

The Yunnan deployment opens a new technical pathway.

Not just for one region.
But for any power grid facing:

• Mountains

• Long transmission corridors

• Harsh weather

ZIYAN will continue working with industry partners to push intelligent, automated UAV inspection further.

Because efficiency isn’t about flying faster.
It's about flying smarter.
