Three-phase dry type distribution transformer

Three-phase dry type distribution transformer

Short Description:

The no-load loss of the amorphous alloy dry-type transformer is 75% lower than that of Group 1 in Table 4 of GB/T10228, and the load loss is 15% lower than that of Table 4 of GB/T10228. It is the most advanced energy-saving dry-type transformer in the world.

    Overview details 

    The no-load loss of the amorphous alloy dry-type transformer is 75% lower than that of Group 1 in Table 4 of GB/T10228, and the load loss is 15% lower than that of Table 4 of GB/T10228. It is the most advanced energy-saving dry-type transformer in the world.
    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.
