── DRY-TYPE TRANSFORMERS ──
F Class cast resin transformers
At Tesla Transformers, we manufacture three-phase transformers encapsulated in Class F epoxy resin, with power ratings of up to 20 MVA and voltages of up to 52 kV. These transformers, designed in accordance with NTC, RETIE, and IEC-EN standards, offer a high level of safety and resistance in demanding environments. The autoclave encapsulation process and the use of Class F materials guarantee excellent insulation and protection against moisture and contamination.
In addition to their robustness, our Class F encapsulated transformers are characterized by their efficiency. The grain-oriented steel magnetic core minimizes losses and noise, while K-factor designs allow for effective harmonic control. We offer air cooling options and customization with temperature monitors, surge protection, and bimetallic connectors.
Three-phase
Up to 5000 KVA series 36 / 1.1 kV
Class F encapsulated dry transformers are designed for applications requiring high resistance and reliability. Their Class F insulation (155°C) ensures excellent thermal performance and durability. They are encapsulated in epoxy resin, which protects them against moisture, dust, vibrations, and contaminants, making them ideal for polluted environments. They do not use oil, reducing fire and maintenance risks. They are compact, quiet, and suitable for use in industries, commercial buildings, mining, photovoltaic systems, and areas with harsh environmental conditions.
