One of the common phenomena in electric cables making users extremely confused is that the conductive core of the wire gets oxidised. How to recognize this phenomenon? What is the risk of using an oxidised power cord? What is the cause and how to prevent it? These concerns of customers will be answered by Tran Phu Electric Mechanical shortly in this article.
The oxidised phenomenon of wires
Oxidation occurs on the conductive core of a wire. In this case, the copper core of the wire will be dull, turning to black yellow or all black instead of the usual red yellow. Therefore, the phenomenon of oxidized electrical wire is also called the phenomenon of black copper wire. This situation also proves that the conductor has changed its properties and specifications.

The risk of using oxidised wire
Oxidised wires not only cause loss of aesthetics for the product itself but also have a high potential risk because it no longer guarantees the former quality. When installing this type of wire for use, due to the change of copper material, the wire can be brittle, easy to break, difficult to bend according to the design of the project. Joints from oxidised wires are difficult to link together and quickly disengage. The wire will also sag, slacken when hanging on the pole.
Using oxidised wires has many potential dangers
When the rusting wire is damaged, the electrical conductivity also decreases significantly, causing large power losses. During usage, this wire is very easy to heat, to age the insulation in the long-term which causes the cord to be exposed, leading to serious danger of electric leakage, electric shock, fire, etc.
In the case of an accident, the cost of replacing power lines is high, aside from the complicated remediation. As in the current context, most of the designed projects are installed concealed wiring systems.
In short, using oxidised wires is dangerous which causes damage to money and effort when repairing. Therefore, customers should absolutely not subjectively use these corrosion wires without the commitment of a technician or manufacturer.
Causes and measures to prevent corrosion wires
There are 4 main causes of oxidation.
- Due to poor quality wire
- Due to the mistaken installation of wiring
- Due to the use of electrical equipment not under the design
- Due to the incorrect method of storing wires
Typically, wiring used in the home will be installed following the purpose, location, and user mode. Therefore, the discolouration of the copper conductor possibly is caused because the conductor used is not suitable for the load, producing heat leading the core to oxidize. Besides, this may also occur in the case of improperly positioned wiring or jointing. For these two reasons, consumers should be aware during usage and consult with experts like electricians when installing or repairing electrical appliances in the home, upgrading the electrical system.
As to the cause of oxidised wires due to improper storage methods of electric wires, consumers should keep in mind these manufacturer's comments of the product in the leaflet accompanying:
- Store conductor in a dry place, without corrosive chemicals, without soaking in water.
- Use plastic flexible plugs to seal the ends of wires while waiting for the connector.
- Do not allow the connection terminals to come into direct contact with water (rain), plastering mortar, or moist environment.
- When there are insufficient ends or individual strands, as for multi-strands wire, the good insulating tape must be used to tightly tighten these wires.
The copper material source has a direct effect on the conductor quality
A deeper cause of oxidation is the source of poor quality, impure copper. For this reason, the conductor may have become rusting even when the customer has not used it. Poor quality, counterfeit or fake cords are the products that are most frequently at fault in this situation.
Note for customers when buying power cords
Careful selecting and buying electric cable products is the first task that customers need to perform to prevent oxidation. Currently, on the market, there are many types of poor quality wire, counterfeit and fake goods. Therefore, customers need to be sharp to avoid being deceived.
Particularly for Tran Phu's power cable products, customers are provided with a separate application to support the inspection of genuine goods and many other utilities. Technology integrated with the Tran Phu app will help users lookup for high accuracy information quickly with very simple operations.
Customers can easily install the application to your phone via the following link:
