Medium-voltage systems

Our medium-voltage division is very active in various areas. We not only place new concrete and interior boxes but also have the necessary expertise to maintain and renovate your existing boxes. And our team is excellent in connecting medium-voltage cables via professional coupling sleeves.

Specific training courses

Customising and/or expanding your existing systems in accordance with current legislation holds no secrets for our employees, who follow specific training courses for this. The maintenance and renovation as well as the placing of your box are always done with the greatest of care for quality and safety.
