Prysmian tower

We are building a tower to produce marine cables for Prysmian Group's production facility in Kirkkonummi. At the end of 2023, the building claimed the title of the tallest building in Finland, proof of our professionals' expertise in demanding industrial construction projects.

We are building a tower intended to hold submarine cables for Prysmian Group's production facility in Kirkkonummi. The tower has reached its highest point and is currently the tallest building in Finland.

High Technology in the Tower

Prysmian Group is implementing a new, even higher vertical vulcanization line in the tower, which is top-of-the-line cable manufacturing technology. Vertical vulcanization is an important part of the high-voltage cable manufacturing process. The tower is built using slip-casting technology and has 23 floors, with different work phases progressing simultaneously in different stages. The investment includes several other new production facilities along with the new cable tower.

In addition to the tower project, YIT has started a contract that includes the expansion of four hall buildings and the construction of a new material warehouse in the area. The new premises will have an area of 26,000 m². The contract includes a lot of demanding foundation construction work, concrete and steel structure work, and building technical work.

Promoting the Green Transition

By investing in Kirkkonummi, Prysmian Group is responding to the growth in demand for land and sea cables spurred by the energy transition and related technology. High-voltage submarine cables are used for the electricity transmission of green transition investments, such as offshore wind farms.

YIT was selected as the implementation partner for the cable tower project in the summer of 2023. The tower reached its ridge height of 185 meters by the end of 2023. The tower is scheduled to be completed in the summer of 2025. The entire agreed contract is estimated to be completed in June 2026.
