How to prevent oxidation of copper conductors in cables?

Facing copper conductor oxidation is a problem that many cable industries will face in the manufacturing process, because once the copper conductor is oxidized, it will cause the performance of the cable to decline, power transmission and other problems, which will have a certain impact on the reliability of the cable. So, what are the reasons for the oxidation of copper conductors? How to deal with copper conductor oxidation? The next blog post will tell you about the corresponding measures.

Application of Copper Conductor in Cable

Copper wires are widely used in the electrical field because of their good electrical conductivity and ductility. Copper conductors play an important role in power transmission, industrial production, construction, transportation, new energy and other fields.

1. Power transmission: Copper wires are usually used in power systems. Copper conductors can withstand higher current loads and longer cable distances while reducing power loss. The use of copper conductors in power systems can also improve the reliability of power systems.

2. Industrial production: Copper wires are used in industrial production to transmit power and signals. In automation systems, communication systems, computer systems and other fields, copper wires can transmit high-speed and high-precision signals.

3. Construction: Copper conductor PVC insulated wires are widely used in construction fields, such as power supply systems and municipal engineering. Copper conductors are able to withstand extremely high loads while also increasing the safety and reliability of buildings.

4. Transportation: Copper conductors are widely used in the field of transportation, such as automobiles, railways, aviation and other fields. Copper conductors can withstand high temperature, high pressure and high strength application environments, improving the safety and stability of transportation systems.

5. New energy field: In the field of new energy, such as solar energy, wind energy and other fields, copper wires can withstand the application environment of high voltage and high current, and improve the production efficiency and reliability of new energy.

 

What are the reasons for the oxidation of copper conductors?

The main reason for the oxidation of copper conductors is that the oxygen in the air reacts with copper to form copper oxide, which makes the surface of copper conductors black. At the same time, moisture will also promote the occurrence of oxidation reactions, resulting in oxidation of copper conductors. In some special environments, such as high temperature, high humidity, etc., the copper conductor will oxidize faster.

 

How to deal with copper conductor oxidation?

1. The oxidation rate of copper conductors is closely related to the ambient humidity, so it is very important to keep the manufacturing workshop or equipment dry. Dehumidification equipment or desiccant can be used to control the humidity of the environment and avoid long-term exposure of copper conductors to humid environments.

2. During the manufacturing process, vacuum packaging or inert gas protection can be used to isolate the copper conductor from air contact and prevent oxidation. In addition, some copper products that have not been used for a long time can be coated with oil or wax to isolate the air.

3. Use a suitable copper rod processing technology on the surface of the copper conductor, such as continuous annealing, stranding, etc., to form a passivation film on the surface of the copper conductor to prevent oxidation.

4. The acid-base environment will accelerate the oxidation of copper conductors. Therefore, in the process of manufacture and use, copper conductors should be avoided from contacting acid and alkali substances, such as acid, salt, alkali, etc.

5. The use of antioxidants on the surface of copper conductors can effectively slow down the oxidation rate. Antioxidants react with copper to form a protective film that prevents oxygen and moisture from coming into contact with copper conductors.
