If the conductor (copper wire) turns black, will it affect the use of the cable?

Influencing factors

There are many reasons why copper core conductors appear black, the main factors include

1. Oxidation: When the copper core conductor is in the air or at high temperature for a long time, the copper surface will oxidize with the oxygen in the air, resulting in a black color. 2. Pollution: After long-term exposure to a polluted environment, the surface of the copper core conductor will Dust or other contaminants may be present, causing blackening.

Influence

Although the black appearance on the surface of the copper core conductor will not have a direct impact on the conductive performance of the cable, the appearance of black color indicates that the copper core conductor may have quality problems, such as improper production operations and aging problems caused by long-term use. These problems will affect the durability and life of the cable, so they need to be dealt with promptly.

solution

If the copper core conductor appears black, it is recommended to take the following measures

1. Check the production process to avoid quality problems caused by improper operations. 2. Choose high-quality wires and cables to ensure good durability and lifespan of wires and cables 3. Regularly maintain and inspect wires and cables, including checking surface conditions, cleaning, packaging, etc.

The black appearance of the copper core conductor indicates that there may be quality problems in the wires and cables, which will affect the service life of the wires and cables. In order to ensure the durability and life of wires and cables, and to ensure the safety and integrity of people and property, it is recommended to adopt the above solutions to ensure the quality of wires and cables.
