Today, Vattenfall installed our marker balls above the E4 near Hyltena in Jönköping 😊
So if you’re driving past – look up!
The marker balls make power lines visible to aircraft and helicopters, especially during poor weather conditions. Pretty impressive to see in real life 😅
And honestly… would you dare to hang in a harness and install one of these several metres up in the air yourself? Be honest 👀
If you’d like to learn more about our marker balls and other solutions for field work, come and meet us at EBR in Karlstad!
You’ll find us at the Overhead Line and Groundwork stations ⚡
