CCA Ethernet Cable Network Patch Cords
What is CCA ethernet cable?
Copper clad aluminum ethernet cable(CCA ethenet cable) refers to a ethernet cable that is wrapped with CCA conductor of the wire, and then added with an insulation layer(mostly PE material) and a sheath layer(PVC, LSZH, PE material). It can protect the CCA core to a certain extent and improve the strength and corrosion resistance of the wire. Like pure copper network cables, copper clad aluminum network cables can also transmit data.
Characteristics and effects of copper clad aluminum ethernet cable
- 1. Low conductivity. The conductivity of copper clad aluminum is about half that of pure copper, which means that when transmitting signals, the resistance of copper clad aluminum will be relatively large and signal attenuation will easily occur.
- 2. Easily produce electromagnetic interference. The electrical conductivity of copper clad aluminum is not as good as that of pure copper, and it is prone to electromagnetic interference. Especially during high frequency signal transmission, the electromagnetic interference problem of copper clad aluminum is more serious.
- 3. Relatively short service life. The service life of copper clad aluminum ethernet cables is generally about 3-5 years. After long term use, due to the oxidation of aluminum and the decrease in conductivity, faults such as wire breakage are prone to occur.
How to extend the service life of CCA ethernet cables?
In order to extend the service life of CCA ethernet cables, it is recommended to choose ethernet cables made of high copper percent CCA materials. This CCA has good electrical conductivity, which can effectively reduce signal attenuation and avoid electromagnetic interference problems.
In addition, when using ethernet cables, you should pay attention to the following points:
- 1. Avoid excessive bending, twisting and pulling to avoid damage to the core in the wire.
- 2. Avoid being close to electrical equipment and power cords to avoid electromagnetic interference.
- 3. Regularly check the connector of the ethernet cable to ensure that the connection is firm and to prevent the plug from loosening when walking or moving the device.
Advantages of copper clad aluminum ethernet cable
1. Lower price: Compared with pure copper wire, the cost of copper clad aluminum wire is lower;
2. Lighter weight: The density of aluminum is smaller than that of copper, so a copper clad aluminum wire of the same length and specification is lighter than a pure copper wire;
3. Stable electrical performance: The copper clad aluminum wire has been optimized and designed, and its electrical performance is equivalent to that of pure copper wire;
4. Environmental protection and energy saving: The production process of copper clad aluminum wire consumes less energy, and aluminum is a recyclable material.
Distinguish between copper clad aluminum ethernet cable and pure copper ethernet cable
So how do we test that the ethernet cable is made of oxygen free copper?
1. Measure resistance value
ethernet cables made of oxygen free copper have high copper content and contain very trace amounts of oxygen and some impurities. The purity of copper is greater than 99.95%. The resistance of a single piece of oxygen free copper is within 30Ω, and the maximum will not exceed 32Ω.
2. Look at the thread skin
The ethernet cable sheaths made of oxygen free copper are made of new materials both internally and externally. ethernet cable sheaths are divided into new materials and secondary materials. The secondary materials are also secondary recycled materials. The threads of the new material are bright and shiny, and the inner threads can be stretched. The color of the second material is dull and dull, and the inner threads break when pulled.
3. Scrape with a knife
ethernet cables made of ordinary materials are usually plated with a layer of oxygen free copper on the outer layer of the conductor to ensure normal signal transmission, such as copper clad aluminum, copper clad silver, all copper ethernet cables, etc. So use a knife to scrape off the outer layer of the conductor to see if the color inside and outside the conductor is the same.
4. burn with fire
Burn the conductor with fire for about 6 seconds. The copper clad aluminum ethernet cable will soften. The surface of the all copper ethernet cable and the oxygen free copper ethernet cable will oxidize and turn black. Wipe it with a rag or paper towel. You will find that the colors of the inner and outer conductors of the all copper ethernet cable are different (from cable Ph.D.), the color of the inner and outer conductors of oxygen free copper ethernet cables is not much different.
5. Cross Section
If you look closely at the cross section of the conductor, you will find that the cross sections of ethernet cables of different materials are different. The cross section of copper clad aluminum is white, the cross section of all copper has micro white spots, and the cross section of oxygen free copper ethernet cable is Uniform yellow color.
For example, at a short distance of 1 to 5 meters, the ethernet cable material has minimal impact on the ethernet environment, and for home use where ethernet cables can be replaced, short distance copper clad aluminum ethernet cables will not greatly affect the experience.
In fact, if we choose a good supplier and manufacturer, we can test the channel of the CCA ethernet cable to 80 meters and the link test to 90 meters. There is no problem in passing the fluke test to 70 meters. It can be used as a daily ethernet jumper. No problem at all, and the price is quite favorable.
