Transformer coil winding material refers to the circuit part of transformer, which is wound by copper conductor or aluminum conductor with high conductivity, and is used in power system. The winding shall have sufficient insulation strength, mechanical strength and heat resistance  。


 
Windings are usually divided into layer type and cake type. The wire turns of the winding are arranged in sequence along its axis and continuously wound, which is called layer winding. Generally, each layer of layer winding is cylindrical, so the winding composed of two layers is called double-layer cylindrical type; A multi-layer cylinder is called a multi-layer cylinder.
 
Transformer coil winding material is made of copper conductor or aluminum conductor with high conductivity. The winding shall have sufficient insulation strength, mechanical strength and heat resistance  。 The coil structure is divided into foil type and wire winding mode. The oil tank can adopt corrugated or chip radiator structure. For the transformer with air-cooled structure, the fan can be installed on the chip radiator of the transformer to provide additional cooling capacity for the transformer.

The layer winding has compact structure, high production efficiency and good resistance to impulse voltage, but its mechanical strength is poor. The cake winding has good heat dissipation performance, high mechanical strength and wide application range, but its performance of withstanding impulse voltage is poor.
