1.8 MW of emergency power for one of the largest tunnels in Finland
The one kilometre long Liipola tunnel is part of the construction of the new Lahti ring road in southern Finland.
HIMOINSA, through its distributor KW -set Oy, has supplied 1.8 MW of emergency power to the Liipola tunnel in southern Finland. A new infrastructure created around the Lahti bypass project managed by the Transport Agency of Finland, the City of Lahti and the County of Hollola.
The project has required to guarantee the lowest noise levels due to the fact that the town of Liipolanmäki and a residential area with flats are located above the tunnel. For this reason, a silencer has been installed next to the generator, allowing sound levels of 45dBA at 40 m.
Because of the depth of the tunnel there was some difficulty in installing the equipment; "the tasks of moving and setting up a generator with dimensions of 6 meters long and a height of almost 3 meters, have not been an easy job, especially when the tunnel has a limited height"; points out Jimi Nurmi, Technical Salesman in KW-SET, who recognises the quality of HIMOINSA equipment and values very positively the response capacity of the generator to any failure.
