Made with grain oriented magnetic laminations cut at 45° and assembled with the step lap method.
Manufactured in-house and galvanized to allow installation in even the most aggressive environments.
Vacuum impregnated with class H polyester resin.
GBE produces single-phase and three-phase transformers with air insulation, with rectangular cross-section up to 1000 kVA and circular cross-section for higher powers. The product offered is intended for the low voltage distribution market, especially for special applications, specific operating classes for converters and all types of installation: marine, offshore and onshore, mining, wind power and more.
The windings are made with copper and/or aluminium conductors using vacuum impregnation in autoclaves with class H polyester resins, which give our products mechanical strength, low operating noise and excellent moisture and pollution resistance.
The core is made from low-loss grain oriented magnetic laminations (CRGO) cut at 45° with step lap construction. Unlike our competitors, which use non-oriented magnetic laminations cut at 90°, the transformers we provide have high operating performance, ensuring core losses that are three times lower and minimal noise.
The metalwork is galvanized and is secured directly to the core columns. Moreover, the transformers can be equipped with profiles for anchoring to the ground, or trolleys complete with swivelling wheels.
And, if a specific IP must be guaranteed, GBE offers a new range of protective boxes with self-supporting panels made of pickled or galvanized sheet metal, depending on the installation type. All boxes are painted with high-resistance polyester epoxy coatings for installation in the most aggressive environments.
