    11kV - 1600kVA Cast Resin Dry Type Transformer Air Cooling Fan Low Noise

    11kV - 1600kVA Cast Resin Dry Type Transformer with Airforced Fan (ONAF) , Three Phases


    1. Low loss, low noise, low partial discharge, high reliability.
    2. Strong capability with anti-short circuit, high anti-lightning impulse capability.
    3. HV coil is vacuum casted with epoxy resin with pressure, capabilities for better the cast without pressure.
    4. Simulating analysis being used in the core model, the resonance can be avoided and the noise is reduced. Simulation calculation and analysis of lighting impulse wave are applied to the HV Coils; anti-lighting impulse capability is improved.


    The core can be constructed of the best quality low loss, cold rolled, grain oriented electrical steel laminations.

    All core plates can be insulated from one to another to reduce the loss to a minimum, and the core can be held together by bolts and clamping plates all of which can be adequately insulated. The completed core can be provided with lifting eyes to facilitate its removal from transformer tank and prevent movement during transport or service. All steel sections used for supporting the core are to be thoroughly sand blasted after cutting, drilling and welding.

    The core can be protected against corrosion by a resin or special varnish coat, thick enough to give adequate protection.

    2. Winding and Insulation Level:

    All windings can be made of high conductivity conductors of best quality and shall be fully insulated to IEC 60076-11, and for a system highest voltage of 12.0 KV. The insulation shall be Class “F” to British Standard Specification No. 2757.

    The HV-LV winding can be (CU.– CU.) or (Al.– Al.) or (CU.– Al.), and can be (wire/foil/ sheet).

    Both H.V. and L.V. windings can be cast under vacuum into moulds with reinforced epoxy resin. The windings shall be suitable for operation under the climatic conditions where the humidity may reach as high as 100%.

    It can also be possible to energize the transformer after long periods of storage or being dead without any need for drying.

    Cast Resin Dry Type Transformer, Low Noise, Low Loss and Low Partial Discharge.
