Product Description

Introduction: The cable paper-covered wire includes cable paper covered aluminum wires and cable paper covered copper wires. They are made of oxygen-free copper rods or electrical round aluminum rods that are annealed after being extruded or drawn by a specification die, and then wrapped two or more layers on the copper (aluminum) conductor Insulating paper (including telephone paper, cable paper, high-voltage cable paper, turn-to-turn insulation paper, etc.) winding wire, suitable for oil-immersed transformer coils and other similar electrical winding wires. The bare copper (aluminum) conductors produced by the extrusion process are ideal materials for the production of cable paper covered wires.

Transposed conductor refers to the combination of a number of enameled copper flat wires into two rows with wide surfaces in contact with each other, and according to the requirements on the top and bottom of the two rows of enameled wires along the narrow side of the same direction of transposition, and electrical insulation tape is used. As a multi-layer continuous and tightly wrapped composition

 

The windings of large power transformers use transposed conductors, which can greatly reduce load loss, reduce the temperature rise of winding hot spots, improve the mechanical strength of windings, make the structure more compact, and make coil processing easier. It is widely used in winding design and manufacture.

 

In the production process of transposed conductors, there will be a problem of poor external dimensions of the transposed conductors. It is often found after the next process that it is irreversible, so that the product cannot be reordered. Winding process processing, adjusting the insulation structure affects the efficiency and product quality. Therefore, it is urgent to solve the existing problems of the large width and height of the transformer winding transposition wire, which is to solve the unqualified quality problem that the wire causes the transformer coil radial and lateral diameter to increase.
