FavouriteGeneral
SCBH15 series amorphous alloy Dry-Type transformer has advanced performance in following points: low no-load loss, fire resistance and self-extinguishing, moisture resistance and maintenance-free. This series product can be applied in any place where the common dry-type transformer worked, such as airport, bus station, urban subway, high-rise construction and power station. And SCBH15 transformer can especially appropriate to be used in the energy-shortage and combustible, explosive places.
