    3 phase High voltage transformer price 50-500kva step up transformer oil immersed power transformer

    3 phase High voltage transformer price 50-500kva step up transformer oil immersed power transformer


    ·Product introduction

    Ai Power offers three phases, oil immersed, and naturally cooled distribution and power transformers. Our products from 10kva to 20000kva with a maximum voltage 35kv are manufacture under the standard of IEC60076. The windings are made of high-grade electrolytic cooper and are concentrically positioned. Usually copper foil is used for the low voltage windings. Round shaped, enamel insulated wires is used for the high voltage windings.


    ·Service conditions

    The altitude shall not exceed 1000m

    Ambient temperature: - 10 ℃ ~ + 40 ℃

    Ceiling Monthly Average temperature: + 30 ℃

    Maximum annual average temperature: + 20 ℃

    Daily temperature difference: 25 ℃

    Seismic crack degree: 8 degrees

    Relative humidity: 95% (+ 25 ℃)


    · Structural features:

    1. The transformer core is made of imported high-quality cold-rolled silicon steel sheet, which greatly reduces no-load loss and no-load current. The core is tightly bound to ensure the compactness and reduce noise.

    2. The high and low voltage windings are made of oxygen-free copper. The low voltage winding of 500KVA and below is of double-layer cylinder structure, of 630kVA and above adopt double helix or four helix structure. High-voltage winding adopts multi-layer cylinder structure.

    3. Dyn11 is used in the transformer connection group to reduce the influence of harmonics on the power grid and improve the quality of power supply.

    4. The transformer is a fully sealed structure, with three coats of primer and one coat of finish paint applied on the inner and outer surfaces. The product is salt fog proof, moisture proof and fungus-proofing, beautiful, durable and reliable

    5. The measured noise value is lower than the standard and maintenance free under normal operation.
