Distribution Transformer

Dry type voltage transformer - single and three phase transformer:

	There are air flows between coils from layer to layer and between coils to core, thus heat escapes quickly, and temperature rises lower.
	There are no flammable insulating material on the coil surface and between the layers coils to avoid the fire hidden danger.
	Small volume, lightweight and good workmanship.
	After vacuum pressure impregnating, the whole transformer is moisture proof and mildew proof.
	Lower audio-noise.
