Abstract

An insulating paper-clad copper-clad aluminum flat wire is provided with a flat aluminum conductor inside, and the flat aluminum conductor is tightly covered with a copper conductor layer, and the copper conductor layer is tightly covered with an insulating paper layer. The copper-clad aluminum flat wire used in the utility model can reduce the AC impedance (resistance) generated by high-order harmonics, and the AC resistance is the main basis for the carrying capacity. According to the principle of skin effect, the surface unit area of the flat wire The current passing through is larger than the current passing through the inner area of the flat wire, that is to say, the inside of the conductor with a large cross-sectional area is smaller than the current passing through the surface of the flat wire in the same area, so the inner conductor of the flat wire and the outer conductor of the flat wire are used Different metal compositions are the most reasonable and economical. The beneficial effect of the utility model is that it has the advantages of low cost, light weight, excellent and stable electrical conductivity, and is suitable for technical fields requiring excellent electrical conductivity.

Description

Insulated paper-clad copper-clad aluminum flat wire

technical field

The utility model relates to a conductor, in particular to an insulating paper-clad copper-clad aluminum flat wire with light weight, low cost, oxidation resistance, excellent mechanical properties and load resistance.

Background technique

In recent years, affected by the international market, the price of copper has soared all the way, which has made the cost of copper-based raw material products continue to increase and the weight is heavy. As a result, companies that use copper as a conductor to produce flat wires are facing tremendous pressure. Due to the disadvantages of high cost and heavy weight of wires, efforts to develop a conductor with low cost and light weight while ensuring the performance of similar products are the goals of development and research by relevant industries.

Utility model content

The main technical problem to be solved by the utility model is to overcome the above-mentioned defects in the prior art. The utility model provides an insulating paper-clad copper-clad aluminum flat wire, which has low cost, light weight, and excellent and stable electrical conductivity. Advantages, suitable for technical fields requiring excellent electrical conductivity.

The technical scheme that the utility model solves its technical problem adopts is:

An insulating paper-clad copper-clad aluminum flat wire is characterized in that a flat aluminum conductor is arranged inside, and the flat aluminum conductor is tightly covered with a copper conductor layer, and the copper conductor layer is tightly covered with an insulating paper layer.

The utility model is an insulating paper-clad copper-clad aluminum flat wire, which is provided with a flat aluminum conductor inside, and the outside is tightly covered with a copper conductor layer, and the copper conductor layer is wrapped with an insulating paper insulating layer. The utility model uses a copper-clad aluminum flat wire to reduce the The role of AC impedance (resistance) generated by high-order harmonics, and AC resistance is the main basis for carrying capacity. According to the principle of skin effect, the current passing through the surface unit area of the flat wire is larger than the current passing through the internal area of the flat wire. That is to say, the inside of the conductor with a large cross-sectional area has a smaller current than the surface of the flat wire in the same area, so it is most reasonable and economical to use different metal compositions for the inner conductor of the flat wire and the outer conductor of the flat wire.

The beneficial effect of the utility model is that it has the advantages of low cost, light weight, excellent and stable electrical conductivity, and is suitable for technical fields requiring excellent electrical conductivity.
