Outdoor voltage transformer

At SADTEM, the outdoor voltage transformer is manufactured by one of two different processes. The first of these involves a metallised resin construction with an isolator in cycloaliphatic resin, while the second method comprises a unit moulded completely in cycloaliphatic resin. These units are available with either one or two insulated poles. The SADTEM range of outdoor VTs also includes a metallised version with a built-in plug for the connection of an insulated cable and also VTs specifically designed for use on the roofs of locomotives. These train models have passed all tests for use on locomotives and conform to all railways standards.
