What is hidden behind the cheap ring transformer?

On the market, why is the same ring type transformer, but the price varies greatly. What's behind the cheap ring transformer?

Recently, a manufacturer of professional power amplifier equipment that had previously cooperated with was found again and asked if he could send 500 ring transformers to him as soon as possible.

At the beginning, he wanted to improve the sound quality of the power amplifier before he found the Gold Stone Electronics transformer. After constant negotiation and improvement of the scheme, our technical R&D personnel and their designers finally handed over three different samples to the customer. The customer said after the test that the three samples all worked well. It would be better if the price could be cheaper. Finally, the customer chose another transformer supplier because of the price disagreement.

It is understood that the ring type transformer provided by his transformer supplier is made of aluminum wire rather than pure copper wire, and the products can be imagined. What is hidden behind the cheap ring transformer? Businesses will have a psychological awareness that is to reduce costs, but it is not difficult to reduce costs, and it is difficult to ensure that product quality is not reduced. Like this customer, he reduced the cost of the transformer, but the quality of the application equipment declined.

The main problem is that the ring transformer is seriously heated, which makes the professional power amplifier of the customer have poor heat dissipation and reduces the operation reliability of the equipment. Although the iron loss of the ring transformer itself is relatively low, the temperature rise of the transformer will be affected by what kind of wire material is used for winding, that is, the line loss. The wire loss is due to the resistance of the coil, but the wire resistance of coils of different materials is different. The greater the wire resistance, the higher the heating. Aluminum wire has the highest resistance, while copper wire has the lowest resistance.

The customer finally chose the Gold Stone Electronics transformer after thinking about it, which was the beginning scene. Don't try to buy a ring transformer cheaply, you will lose more than you gain.
