Transformer can transformer the voltage of a network into the voltage matching the system or load and fulfill power transferring and distributing.Taking the place of transformers with silicon steel core, AMDT can be widely applied in outdoor power distribution networks systems, which is magnificently energy saving and can lessen air pollution. It is especially applicable for areas with insufficient power supply and fluctuating load and where daily maintenance is hard. Since the transformer adopts a fully sealed structure, the insulating oil and the insulating medium are not polluted by the atmosphere, so it can be carried out in a humid environment, making the ideal power distribution equipment in the urban and rural distribution networks.

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