> Product Brief
This transformer can replace the transformer of silicon steel core and is widely used in outdoor power distribution systems. The large-scale operation of this product can achieve good energy-saving effect and reduce pollution to the atmosphere. This product is especially suitable for insufficient electrical energy and load fluctuations in and difficult to carry and insulating medium from atmospheric pollution. This allows it to operate in humid environments. It is an ideal power distribution equipment in the vast distribution network of urban and rural areas.

> Structural Features
◇ The transformer core is rolled with amorphous alloy strip, and the no-load loss is reduced by about 75% compared with that of S9 transformer.
◇ Low voltage adopts copper foil coil to improve the ability of transformer to withstand short circuit.
◇ The transformer connection group adopts Dyn11 to reduce the impact of harmonics on the power grid and improve the quality of power supply.
◇ Vacuum oil injection can completely eliminate air bubbles in the coil and ensure stable insulation performance.
> Conditions of Use
◇ The altitude does not exceed 1000 meters.
◇ The ambient medium temperature is not higher than +40°C: the highest monthly average temperature is +30°C; Maximum annual average temperature +20°C, minimum temperature: -25°C.
◇ Outdoor or indoor.
◇ Transformers operating under special conditions can be provided according to the requirements of users.
> Main Technical Parameters
5kVA~160kVA single-phase double-winding non-excitation voltage regulation distribution transformer
Note 1: The performance parameters of other capacity products are determined by the manufacturer and the user through negotiation.
Note 2: For single-phase transformers with a combination of 2× (0.22~0.24) kV with low voltage, when the low voltage is (0.22~0.24) kV, the capacity is halved (except when used in parallel).
Note 3: For other short-circuit impedance values, the user and the manufacturer are determined through negotiation.
Note 4: If the user needs, other loss values can also be selected.
30kVA~2500kVA three-phase double-winding non-excitation voltage regulation distribution transformer
Note 1: When the core is a three-phase three-column, Yyn0 coupling group can also be used as needed.
Note 2: For three-phase jade with a rated capacity of 500kVA and below, the load loss value above the slash in the table applies to the Dyn11 coupling group, and the load loss value below the slash line applies to the Yyn0 coupling group.
Note 3: Other loss values are also available if the user requires.
Note 4: Three-phase transformers with other high-voltage tap ranges are available according to user needs.
