With the increasing market development space of toroidal transformers, transformers made of various materials are also emerging in an endless stream. The material of the wire is different, and the performance, life, etc. will be different. We bought the transformer and didn't see the production process, so we don't know how to tell whether the toroidal transformer is made of copper wire or aluminum wire, today we will briefly analyze it.
According to the density of copper wire and aluminum wire, the density of copper wire is higher than that of aluminum wire, and it can be said that the density of aluminum wire is 1 3 of copper wire. We know that in water, if the density of the object is greater than that of the water, it will sink, which proves that the object is heavier. So we conclude that copper wire density is greater than aluminum wire, and copper wire will be heavier than aluminum wire. Then we pick up the transformer and compare their weights to preliminarily distinguish which is copper wire and which is aluminum wire.
The tensile strength of the copper wire itself will be much stronger than that of the aluminum wire, so the copper wire is not easy to break during processing. This is where the question of the service life of the transformer comes in. When we accidentally bump the transformer and use it for a long time, the copper wire will be less likely to break than the aluminum wire and more durable. We will test the transformer when it is energized, and we will find that the heat of the transformer made of copper wire will be lower than that of the transformer made of aluminum wire, because the thermal conductivity of copper wire is better than that of aluminum wire, and the work efficiency is higher!In terms of color, the color of the copper wire is golden yellow, and the aluminum wire itself is silver. We can see the color of the wire through the transparent insulating film on the outer layer of the transformer, which can be distinguished.
From the above aspects, we can easily distinguish whether the transformer is made of copper wire or aluminum wire. It is worth reminding that the selection of copper wire products for household equipment accessories will be better than aluminum wire products. Because the conductivity of aluminum wire is poor, it is easy to heat, causing the equipment joint to loosen and cause fire. Shengyuan Electric's toroidal transformer is made of all-copper wire, which has the characteristics of long life, high efficiency and sufficient powerIf you need further consultation and related information, you are welcome to contact our ** customer service staff at any time.
