GBE SpA manufactures resin transformers up to a power of 30 MVA and voltage of 52 kV, with Off Circuit or On Load Tap Changer. The constructive design of a power transformer is completely different from that of a distribution transformer. The masses involved are quite big, and at the design stage it is necessary to take into account not just the mechanical and electrical stresses but also the issues related to the materials expansion during operation. A correct distribution of the electric field within the windings must be ensured to avoid partial discharges issues or problems related to the overvoltage resonance and this is guaranteed by GBE design that considers the proper distribution of the capacities between coils, layers and parts of the coils, and to the ground. For the power transformers, the constructive design takes into account any dimensional aspects of the transformer based on the type of installation and especially the optimization of losses so to guarantee a competitive product not just considering the purchase price, but also the operation cost.
Participation of GBE at the hydroelectric conference in Italy The prestigious annual conference entitled Hydromatters 4.0. recently took place in Padua. GBE SpA with the speaker Eng. Fabio Cavestro illustrated the constructive design used for transformers and reactors subject to occasional, continuous and severe mechanical vibration. During the seminar two types of installation were highlighted […]
A flexible, easy-to-use solution designed by GBE Bunds for oil-filled transformers are a new product developed by the GBE steelworks department. For those installations where this bund has not been included, GBE has developed an extremely flexible solution, designed to protect the environment. The oil bund has been developed in pickled and subsequently galvanized metal […]
