“My advice to newcomers is this: there will be days when you ask yourself whether it's really worth it. You'll ask yourself, “Do I really want to do this?” But if you work with a team that feels like a unit, where you really fit in and can perform well, then you'll want to stick with it. That's when things start to become enjoyable. That's what line construction is all about. It's about teamwork. That's our strength.”

Which mast types are used for overhead line construction?

The type of mast used depends on the requirements and conditions, and can be solid wall, concrete or wooden.

How does overhead line construction contribute towards the power supply?

Overhead lines are a vital part of the infrastructure used to transmit electricity from power stations to cities and industrial areas.

What impact does overhead line construction have on the environment?

We minimise the impact on the environment and increase acceptance through careful planning and the use of modern technologies.

What does restoring overhead lines involve?

The restoration process involves repairing masts, cables and insulators in order to repair any damage and extend their service life.

How long does take to build an overhead line?

The duration varies depending on factors such as the length of the route, the terrain and the specific requirements. However, precise planning enables efficient processes.

Does your company also offer solutions for medium voltage?
