aTSE epoxy-resin dry-type transformers
An excellent environmentally friendly alternative: safe operation, minimal maintenance and virtually unlimited installation options, indoors and outdoors. Manufactured in the European Union to IEC 60076 and EN 50588-1.
- Metal parts of aluminium or its alloys.
- Resistant to ambient temperatures up to 55 °C, short circuits, overloads, harmonics and lightning.
- Minimal fire risk thanks to non-flammable insulating materials.
- No liquid cooling, minimal maintenance and a service life of over 25 years.
- Grain-oriented silicon-steel core, aluminium foil windings, PTC or PT100 sensors and off-circuit tap changer.
- Options: monitoring, forced ventilation, anti-theft galvanized steel enclosure and customization.
- Partial tests during manufacture and tests on the complete unit; special tests on request.
