Amorphous alloy oil transformer
- Low loss: the core of transformer is coiled by amorphous alloy, and the no-load loss ratio is about 75% lower than that of S9 transformer
- Resistant to short-circuit: the transformer low voltage is made of copper foil coil to increase the capacity for undertaking short-circuit.
- Optimize the power quality: the connection group of transformer is Dynll to reduce the influence of harmonic on grid and improve the power quality.
- Maintenance-free: the tank and cover are an integrated fully-enclosed structure, long in service life and free in maintenance.
- Good insulating property: the transformer is filled with oil in a vacuum mode to completely eliminate the bubbles in coil and ensure the stable insulating property
- Installed in high-rise buildings, business centers, metros, airports, stations, industrial and mining enterprises and power plants, especially applicable to the places with high fire protection requirements such as inflammables and explosives.

Note: 1: When the iron core is three-phase and three-column, Yyn0 connection group can be used according to the need.
2: For the transformer with the rated capacity of 500KVA and below, the load loss above the inclined line of table is applicable to Dyn11 connection group, and the load loss below the inclined line is applicable to Yyn0 connection group.
3: Other loss values can be used if the user needs.
4: Other high voltage tapping three-phase transformers can be provided according to the user's need
