Our reliable high safety dry-type distribution transformers offer maximum availability at low maintenance costs and are available with ratings from 250 kVA up to 5000 kVA and voltage ratings up to 36 kV. Our standard transformer comply to IEC 60726 and IEC 60076

The mouldless-vacuum-casting and the waterproof windings allows application in an environment with up to 100% air humidity and chemical aggressive atmosphere. The high thermal time-constant as well as the vertical and horizontal cooling ducts provide excellent cooling allowing high short time overload and full power handling capabilities even with IP 45 type protection.

Our dry-type transformer are especially designed to offer minimum combustion energy and are a perfect choice for installations where high personal safety is required.

All transformers are designed and manufactured according class H(180°C) and to the highest climatic, environmental, and fire specifications. They comply to climatic class "C2" (ambient temperature -25°C), environmental class "E2" (humidity up to 95% with high pollution) and fire behaviour class "F1" (self-extinguishable transformers without emission of opaque smoke). All transformer use halogen-free materials.

Our raw-material and final product laboratories are equipped with the latest and best technology in order to carry out the most severe checks and tests requested by national and international standards for equipment used to manufacture transformers.
