SBH15 transformer with amorphous alloy core produced by our company adopts new magneto conductive material, i.e. amorphous alloy core. It is the most ideal distribution transformer in energy saving at present, especially suitable for the rural power grids and the developing districts, where the load factor is rather low. The amorphous alloy cored power transformer has advantage of low no-load loss, energy-saving and environment-protection, and it is fully in accordance with the national industrial policy ”resource-saving, environmentally-friendly, and the establishment of reef society". In the past twenty years, it has been wildly used in domestic and foreign power grids.
Working conditions:
- Altitude: ≤2000m
- Maximum environmental temperature:
- Maximum annual average temperature
- Customized products are available.
Performance characteristics:
- The core adopts amorphous alloy as conductive material. It’s an amorphous strip alloy treated by rapid cooling and spray process, with iron boron as raw material. Because of properties of soft magnetic and narrow hysteresis loop area, the amorphous alloy only needs a small magnetic power, so transformer made of amorphous alloy has low no-load loss.
- The transformer core use amorphous alloy wrapped with strip three phase five column type structure, which makes the height of transformer is lower than that of with three phase three column type structure. With rectangular core section, its lower yoke can be opened for installing coil easily
- Low voltage winding usually adopts copper foil winded cylindrical structure except of using copper conductor for small capacity ones. High voltage winding uses multi-layer cylindrical structure, which makes a balance ampere-turns distribution, small magnetic-leakage loss, strong mechanical strength and good anti-short circuit ability.
- The apparatus body assembly, tank structure, protection function are totally similar with that of sealed oil type amorphous alloy distribution transformer, which also adopted no-hanging heart structure. The transformer uses vacuum drying, vacuum oil filter-injection process. Corrugated tank, no oil storage tank structure.
- The load loss of his kind of transformer is the same with S9 series, while the no-load loss of SBH15 transformer is 75% lower than that of S9 series; the no-load loss of SBH16 transformer is 80% lower than that of S9 series.
- No need to change oil in normal operation, which greatly reduces the transformer maintenance cost and prolong the life.
- It’s possible of recovering costs increased than silicon steel corer transformer in four year, after calculation for annual power consumption, annual power loss cost and annual electricity charge saving.
