What Are the Advantages of Using Continuously Transposed Conductors?

Continuously Transposed Conductors can greatly reduce the load loss, reduce the temperature rise of the winding hot spot, improve the mechanical strength of the winding, make the structure more compact, and make the coil processing easier. Therefore, once the transposed conductor comes out, it has been used in the design and manufacture of large power transformer windings. widely used.

What are the advantages of using Continuously Transposed Conductors?

Compared with ordinary flat wires, Continuously Transposed Conductors have many advantages, and at the same time, due to the relatively small size, the manufacturing cost of transformers is reduced.

1. The loss of discrete field is reduced due to the use of multiple single wires of small cross-section instead of a flat wire of large cross-section.

2. Compared with multiple parallel self-insulated single wires, since the Continuously Transposed Conductor is an enameled single wire, the thickness of the paint film is much thinner than that of the previous paper insulation, but the withstand voltage is several times that of the paper insulation. The insulation thickness of the common paper insulation is relatively thin, so the volume of the winding is obviously reduced, and the utilization rate of space is effectively improved.

3. Due to the transposition between single wires, the windings have high mechanical strength.

4. Because the insulation thickness is relatively thin, it has high heat dissipation.

5. Due to the thin paint film and insulation thickness, it has better heat dissipation, so it has high thermal stability.

6. Due to the reduction of manual transposition, the winding process becomes simple and the processing time of the winding is shortened. For the transposed wire, winding one turn of the transposed wire is equivalent to winding multiple turns of a single parallel flat wire.

What are the precautions for the use of Continuously Transposed Conductors?

(1) Continuously Transposed Conductors must be cooled in time, and should be covered immediately when the flame is removed;

(2) Pay attention to the tightness after Continuously Transposed Conductors. All the red-hot wires must be wrapped with industrial wipes. When the industrial wipes are spread, the coolant will rapidly vaporize due to the high temperature of the wires, and the generated moisture will Exhaust the air inside, and keep the water vapor out, and do not expose it to the air before the wire is cooled;

(3) After the industrial wiping paper that absorbs the cooling liquid is tightly covered, it is necessary to continuously squeeze the industrial wiping paper, so that the cooling liquid inside can be continuously drenched on the high-temperature part of the wire;

(4) Remove the industrial wipes until the water vapor is no longer discharged.
