Product Usage

This product possess such advantages as low no-load loss, no oil, flame retardation and self-extinguishing, moisture resistance, crack resistance, maintenance-free etc. can be used to replace all common dry-type transformers which now are used in many places. They can used in high buildings, commerce centers, subways, airports, train stations, enterprises and power plants, they are especially suitable for installing and using in such places where strict fireproof requirements, including anti-combustible and anti-explosive, must be meet.
