TRASFORMATORI DI DISTRIBUZIONE IN OLIO OIL IMMERSED DISTRIBUTION TRANSFORMERS
TRASFORMATORI DI DISTRIBUZIONE IN OLIO OIL IMMERSED DISTRIBUTION TRANSFORMERS
The oil-immersed distribution transformers are constructed according to IEC 60076-13 standards and comply with Ecodesign regulations, EN 50588-1, tier 1 and 2. The core is made of cold-rolled oriented grain steel with low losses and noise. Windings are typically made of electrolytic copper, with wide oil ducts for optimal oil circulation. The tank is available with fins or radiators, featuring oil-resistant internal and corrosion-proof external painting. Transformers can be filled with mineral oil or biodegradable vegetable oil FR3, with the option for insulating silicon oil.
Functional Characteristics
These transformers are suitable for humid environments with electrically conductive dust and can operate in temperatures below -25°C with appropriate oil. They have low noise levels and reduced or absent partial discharges.
Standards and Testing
Transformers adhere to IEC 60076 standards and undergo routine tests. Optional tests include temperature rise, full wave impulse, and noise level tests.
Accessories
Standard accessories include an off-load tap changer, oil conservator, oil level indicator, and more. Optional accessories include cable boxes, Buchholz relay, and centralization box.
Installation and Usage
Suitable for both indoor and outdoor installations, even in challenging environments.

Caratteristiche tecniche Standard: i trasformatori sono costruiti in base alle norme IEC 60076-13 (o altri standard a richiesta) e con efficienza come da norma Ecodesign, norme EN 50588-1, fase 1 e 2. Nucleo: il nucleo è costituito da lamierino magnetico a cristalli orientati con basso livello di perdite e di rumore. Avvolgimenti: gli avvolgimenti sono realizzati di norma con conduttori in rame elettrolitico. Ampi canali, assicurano una perfetta circolazione dell’olio nelle bobine. Prima del montaggio gli avvolgimenti sono sottoposti ad essiccazione. Cassa: esecuzione normale a radiatori o a...

Technical Features Standard: the transformers are built in accordance with IEC 60076 standards (or other International standards) and with efficiency as per Ecodesign regulation, norms EN 50588-1, tier 1 and tier 2. Core: the core is built up of cold rolled oriented grain steel sheet with low specific losses and noise. Windings: the windings are made as standard of electrolytic copper. Wide oil ducts allow a perfect oil circulation, also inside the windings. Before assembling, the windings are submitted to drying process. Tank: standard execution with fins or radiators . Painting internally oil...
