Trihal cast resin dry type MV/LV transformers
Technology
State-of-the art technology, the result of over 70 years’ experience in impregnated dry-type transformers and over 25 years’ experience in cast resin transformers
A magnetic core that minimises :
- losses
- no-load current
- noise
An MV winding comprising coils with a linear voltage gradient from top to bottom, patented by France Transfo and designed to :
- enhance dielectric characteristics
- keep partial discharge at an exceptionally low level (≤10 pC)
A high-voltage casting system based on vacuum cast coating with a fire-resistant filled resin, which provides:
- excellent winding impregnation
- very good thermal and mechanical resistance
- and, above all, immediate self-extinguishing
A pre-impregnated non-cast LV winding, which provides:
- excellent resistance to aggressive industrial environments
- excellent dielectric resistance
- very good resistance to short-circuits
