New Applications for Copper-Clad Steel and Copper-Clad Aluminum Wire

The characteristics and application of copper clad steel wire

1. Characteristics of Copper Clad Steel Wire

Copper-clad steel wire is a composite wire with a steel wire as the core and a layer of copper on the surface.

Copper-clad steel wire has both the following points in performance:

  1. High strength of steel
  2. Mechanical properties of high temperature resistance
  3. High electrical conductivity with copper
  4. High conduction efficiency
  5. Low material cost
  6. High tensile breaking force
  7. Light weight
  8. Wear resistance

Advances in technology and materials have made current copper-clad steel wire easier to draw and process than ever before.

Currently due to high energy prices and material prices. And there is an emphasis on reducing weight, which makes copper-clad steel conductors a good solution for many uses.

Any copper conductor that allows a reduction in diameter as long as improve the strength is a potential replacement for copper clad steel.

2. Applications of Copper Clad Steel Wire

Copper-clad steel wire, it is an ideal product for contact wire using in electrified railways.

In the cable industry, it can replace copper conductor wires as distribution lines or telephone subscriber lines in the communication industry.

In addition, there is another kind of aluminum-clad steel wire with high-carbon steel wire as the core body.

And the periphery is evenly coated with a layer of pure aluminum, which is mainly used for overhead high-voltage transmission and transformation power grids.

Copper-clad steel conductors have been used for many years where robustness is important.

For example, geophysical cables used to connect downhole instrumentation equipment in oil fields.

New uses for copper-clad steel wire continue to develop and evolve in the field.

Although there are many potential new uses of copper-clad steel wire, we use most of them in geophysical and other applications.
New uses of the same broad class of cables for different purposes.

The characteristics and application of copper clad aluminum wire

1. Characteristics of Copper Clad Aluminum Wire

The United States, Britain and other countries in Europe and the United States began to study and apply copper-clad aluminum materials as early as the 1960s.

Japan and other countries have also been developing related materials and entered the practical stage.

Make copper-clad aluminum the third conductor after copper and aluminum.

Since the surface of aluminum is extremely easy to oxidize, the oxide film produced is extremely difficult to remove.

This results in large contact resistance and inability to solder, which seriously affects the popularity of aluminum instead of copper.

The development of copper-clad aluminum has successfully created a turning point for aluminum to replace copper.

As early as the early stage of development, copper-clad aluminum was only used in the wiring of building wires abroad, as well as high-frequency cables and shielded wires for radio and television communications.

Due to the industrialization of the production of copper-clad aluminum conductor materials, the country can gradually meet the needs of mass production.

In addition, copper-clad aluminum has the advantages of light weight, relatively low cost, and stable price.

This overcomes the disadvantages of high copper cost and fluctuating prices.

Therefore, its application range is getting wider and wider.

It has gradually been widely used in motors, enameled wires of transformers, busbars, wires and cables.

Moreover, it is very popular among users and manufacturers.

2. Applications of Copper Clad Aluminum Wire

Because the process and materials of copper clad aluminum have made remarkable progress.

Materials previously difficult to draw into wires smaller than 0.005in.

At present, it has been able to be drawn into 0.005in thin wire in daily production for commercial use.

Such advances offer the potential for revolutionary new uses.

Soaring copper prices have made these new uses economically attractive.

Copper-clad aluminum is the same as copper and aluminum as a conductor.

Theoretically, it can be applied to many occasions.

For example:

  1. Copper-clad aluminum flat wire or busbar can be used in power and electrical industry, such as busbar.
  2. Audio and high frequency video cables, such as CATV wires and shielded wires.
  3. Various motor rectifiers and transformer winding wires.
  4. Engineering wire and cable conductors.
  5. Conductors for power cables, etc.

But the real best use occasion is the field of audio and high frequency video cables.

In addition, some engineering machinery wires and cables are also widely used.
