Compared with aluminum wire and copper wire, there is still a big difference.

First of all, it is the aspect of material. Aluminum wire is mainly made of aluminum, and copper wire is made of copper. Therefore, these two kinds of conductivity are also different. The conductivity of aluminum wire is not as good as that of copper wire, and aluminum wire is easy to be oxidized and its service time is not very long. The quality of copper wire is better and its conductivity is better. It is not easy to oxidize. Now, basically, many people choose copper wire when choosing wires, and its price is relatively higher.

It is generally believed that copper has better electrical conductivity, higher mechanical strength, higher thermal conductivity and higher price than aluminum, which is also true. However, it is also true that aluminum is active and easily oxidized. If copper is used as the transformer, it will make the whole transformer smaller and save the installation location. The most prominent thing is that the short-circuit resistance of the transformer is stronger, which means that the dynamic stability and thermal stability of the transformer are also stronger. Of course, this is relative. Aluminum is around the transformer. As long as we pay attention to this problem in electromagnetic calculation and structural design, we can also ensure that its dynamic and thermal stability can meet the requirements of national standards.

In fact, whether copper wire or aluminum wire is used in transformer, the cross-sectional area of iron core is the same, and there will be no change. As long as the transformer volume is a little different, the aluminum wire transformer volume will be relatively larger, and the copper wire transformer volume will be smaller.

There is also the cost will be different. The price of aluminum wire transformer is low, and the price of copper wire transformer is high. Aluminum wire transformer can save production cost.

How to connect copper wire and aluminum wire, and what are the connection methods of copper wire and aluminum wire?

1. Copper wire and aluminum wire cannot be directly connected. Copper wire and aluminum wire are made of different materials, so their properties are different. If you want to connect them together, you need special treatment.

2. When connecting single-strand copper and aluminum wires with small cross section, connect them with copper wires before connecting them with aluminum wires.

3. When connecting multiple large-section copper and aluminum wires, copper-aluminum transition pipe or copper-aluminum transition clamp should be adopted.

4. If the aluminum wire is connected to the copper terminal of the switch, the copper-aluminum transition nose should be adopted.

Introduction of calculation method of aluminum plate weight

When designing and producing products and purchasing aluminum plates, we need to calculate the cost price of materials. Aluminum plates are usually settled by weight. Here we will explain the calculation of aluminum plate weight, hoping to help friends in need.

When calculating the weight of aluminum plate, we need to know what the actual size of aluminum plate is. A friend with conditions can measure the thickness of aluminum plate with vernier caliper, which is the most accurate degree. It doesn't matter if it doesn't, especially for aluminum plates above 4 mm. Put the aluminum plate on the plane, measure its thickness with a ruler close to the aluminum plate, and record the measurement results. The length and width can be measured with a tape measure. Measure along both sides of the aluminum plate and record the measurement results.

Calculation method 1 of aluminum plate weight

Weight =2.71× length (m)× width (m)× thickness (mm)

The density of aluminum plate is 2.71.

For example:

1m long * 2m wide * 3mm thick aluminum plate.

The calculation method is 1 * 2 * 3 * 2.71 = 16.26kg.

Calculation method 2 of aluminum plate weight

Calculation formula weight of aluminum plate = thickness * width * length * density of aluminum plate

2. Density of aluminum plate Density of aluminum: 2.702g/cm³. Density of aluminum plate: the density of pure aluminum plate is 2.71g/cm³, and that of alloy aluminum plate is 2.68g/cm³.

3. The volume of an aluminum plate with a length of 72.8mm, a width of 38.0mm and a thickness of 3.0mm is V: V = 72.8 * 38.0 * 3.0 (mm) = 8299.20 (mm) = 8.29920 (cm). The mass of the aluminum plate is 8.29920 * 2.71g = 22.4991.
