GEAFOL® CastResin Transformers
GEAFOL® cast-resin transformers are environmentally friendly, dry-type transformers designed for applications requiring special fire security, water protection, or specific construction regulations. They are used to convert voltage levels in distribution networks, as generator transformers, or for operating static converters, with ratings up to 50 MVA and 52 kV.
- Practically maintenance-free with high overload capacity.
- Excellent fire behavior, being flame-resistant and self-extinguishing.
- Environmentally friendly and completely recyclable.
- Available for nearly all standards and regulations.
- GEAFOL Neo: Innovative design, small dimensions, low weight, suitable for up to 6.3 MVA and 40.5 kV.
- GEAFOL: High efficiency, compact design, suitable for up to 50 MVA and 52 kV.
- GEAFOL Converter Transformer: High short circuit withstand capability, suitable for up to 50 MVA and 52 kV.
- Safe and reliable with high voltage strength and moisture resistance.
- Environmentally acceptable with no liquid insulator and low noise levels.
- Economical with high efficiency and simple rearrangement capabilities.
- Adaptable with the ability to increase rating by up to 50% with fans.
- Compact with small ground area requirements.
- Factories located in Mexico, Germany, Hungary, Brazil, and China, each with specific capacity and voltage capabilities.
- Project: PV Plant Porteirinha I for Mori Energia in Minas Gerais, Brazil.
- Customized transformers for 30 plants across 17 cities.
- Specifications include 1000kVA and 500kVA transformers with outdoor IP54 solutions.
