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.
A customised supply for one of the most innovative oil rigs in Europe GBE, a company capable of developing customized solutions covering all kinds of products, satisfying any installation need and managing also the machining processes internally, has played once again a strategic role in one of its recent supplies. For the Tempa Rossa plant, […]
The economic and compact solution for adjusting the grid voltage, optimising the performance of the transformer and reducing losses In most countries in Europe (and around the world), the voltage of the power lines for the distribution of energy varies by more than +/- 10%, no longer guaranteeing the maximum limit as required by EN50160. […]
The aim is to reduce losses and gain in efficiency. GBE are ready, thanks to their high ECODESIGN transformers production. The global commitment for energy efficiency and emissions reduction keeps moving on. The newest European Union Legislation 548/2014 sets the new standards about ecodesign, imposing a drastic reduction on losses of new transformers launched on […]
