Oil Power Transformers
GBE supplies oil power transformers up to 50 MVA with voltage of 145kV (BIL650), with Off Circuit or On Load Tap Changer. TheOn Load Tap Changer can be either external or internal to the transformer tank. The oil power transformer is made according to constructive and design criteria as to ensures the highest operational reliability and a great performance in the electrodynamic stress, as well as excellent isolation so to avoid problems related to possible network overvoltages. The magnetic core is made with high permeability 45 degrees cut steel sheets in the European or American step lap type. The pack tighteners of the magnetic sheets are sized appropriately to ensure the mechanical sealing, noise reduction, and any problem relating to the handling or stresses of the windings. The MV and HV windings are made of a disc or with transposed cable conductors; they are made with horizontal or vertical winding machines by experienced staff in a controlled environment. The positioning of the coils and the gap between them and between the layers is performed according to the precise indications of the electrical design, as well as the type of conductor and the its processing. The drying and pressing process of the windings prior to assembly is fundamental and is carried out in a furnace with dry air circulation, monitored and recorded temperatures.
The power transformer can have two or more windings and can be fitted with compensation winding.
Eco 3+ transformers with amorphous core As of 1 July 2021, all transformer manufacturers will have to strictly comply with the production of transformers classified with the term Tier 2, with the exception of specific applications, as laid down in Regulation no. 548/2014 with Phase 2. However, for over 10 years, GBE has been offering […]
ISO 45001 Certification Workplace health and safety: the personnel are the primary wealth for GBE GBE has integrated its IMS system with ISO 45001 certification to ensure safe and healthy workplaces and prevent work-related injuries and illnesses. For many years, GBE has been in possession of ISO 9001 certification related to product quality and ISO […]
Quay transformers: Shore-to-Ship Respect for the port environment, therefore, reduction of consumption, pollution and noise The regulations in port areas increasingly call for a reduction in the air and noise pollution produced by the ships moored in ports. This requirement is met by using ground power instead of on-board generation during mooring. The shore-to-ship […]
