ELETTROMECCANICA COLOMBO manufactures distribution oil transformers , low voltage/low voltage(LV/LV) medium voltage/low voltage(MV/LV) and medium voltage/medium voltage (MV/MV) up 3,15 MVA and 36 KV.
The transformers are designed in accordance with norms IEC 60076 in order to optimize the efficiency. For European market ,the calculation is made according to Ecodesign regulation, norms EN 50588-1, tier 1 and tier 2.
When the transformers are connected to inverters, the design is made as stated from IEC 61378-1 norms.
For all transformers the large experience, the technological ability connected with high quality guarantees a reliable product with an expected lifetime span in normal condition over 30 years.
The company total Quality management system is based on certified Quality Assurance system ISO 9001- 2015,Environmental ISO 14001-2015,Health and safety ISO 45001-2018.
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 resistant and externally corrosion proof. Execution with conservator or hermetically sealed.
Bushings: are made of brown porcelain, in accordance with UNEL- DIN-ANSI standard or other required.
