The T 97 underground station if space is limited

Tight for space? Due to the extremely compact design of the T 97 underground station, most projects can still be implemented. 

 

The prefabricated underground station T 97 compliant with SN EN 62271 202. The unit can be operated from outside and has a very shallow design

The special features of the T 97 are its extremely low structure height of little more than one metre and the hinged metal roof.

The station is used with the roof open, whilst the technician stands on a false floor, which is approx. 60 cm below ground level. 

The design complies with the latest state-of-the-art technology and meets the requirements of the applicable regulations and technical standards, namely the type test standard SN EN 62271-202 for prefabricated transformer stations. 

Since the interior fittings are installed and the routine testing takes place at the Villmergen factory, the station can be assembled on-site in one day.

Tiefstation T97

The industrially prefabricated building station can be operated from the outside

The T 97, made by Betonbau GmbH und Co. KG, Germany, is a prefabricated compact building station in concrete cabin design. It is an extremely low structure, measuring just over 1 m high and can be used outdoors.

A hinged metal access hatch allows access via stairs to a service floor 40 to 60 cm below ground level.

The stations are fully fitted in our factory, transported by us to the construction site, and installed the same day.

The concrete housing is seamless and comes as a single piece.

Layout and sizes are variable to a certain extent.

The T 97 station model fully complies with the requirements of the Ordinance on Heavy Current Installations and relevant engineering standards, namely SN EN 62271-202 for prefabricated stations utilising high voltage and/or low voltage.
