Depending on the power requirements and local conditions, there are different variants of a transformer station. Compact stations that are not walkable and larger walkable stations are possible. We supply walk-in stations up to a size of 40 feet containers. We also offer transformer stations and individual low- and medium-voltage components for indoor installation.

Whether compact station, walk-in station or stations in buildings. We offer these for rent  or for sale  . Leasing, lease-purchase and financing are also available.

Horstmann und Schwarz offers three different types of transformers: Cast resin, oil or low-voltage transformers with loss class according to new standards of the Ecodesign Directive.

Depending on the requirements, these are suitable for indoor and outdoor installation. We will be happy to advise you which transformer type is right for you. Our transformers are usable for pure supply plants, as well as generation plants to enable the use of the generated energy by e.g. large photovoltaic plants.
