Product Usage
This product has the advantages of low no-load loss, no oil, flame retardant self-extinguishing, moisture resistance, crack resistance 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-proof requirements such as flammable and explosive.
