  • 1966 – The company was founded.It was originally a two-man operation occupying a couple of rented rooms on a backstreet of the German city of Osnabrück
  • 1976 – Relocation to purpose-built, company-owned premises in Hettlicher Masch, Osnabrück/Fledder, occupying 800 square metres.The move coincided with the initial assembly and manufacture of medium-voltage switchgear equipment.
  • 1988 – The existing building was extended to add a further 500 square metres of floor space, by now providing room for 60 employees.
  • 1993 – Construction of new operating premises occupying 2,500 square metres of floor space; in the Anton-Storch-Strasse, Osnabrück, Burenkamp.Extension of the former building in Hettlicher Masch was ruled out due to the restricted size of the surrounding site.

 The company has expanded continuously over time to meet a growing list of requirements.

 Wind power has emerged in recent years as another new market for Isoblock Schaltanlagen,and we have so far equipped more than 300 wind farms, with a total mains-network output exceeding 350 MW.
