Product Usage

This product has the advantages of low no-load loss, oil-free, flame-retardant and self-extinguishing, moisture-resistant, crack-resistant and maintenance-free. Any place where ordinary dry transformers are currently used can be replaced by amorphous dry transformers, which can be used in high-rise buildings, commercial centers, subways, airports, stations, industrial and mining enterprises and power plants. It is especially suitable for installation and use in places with high fire protection requirements such as flammable and explosive.
