What kind of network cable should be used in different situations?

Network wiring is divided into family wiring and project wiring.The demand for transmission of family wiring is not high, but the demand for the price is higher, the amount is less.Project engineering wiring requirements must meet the national standard products, there must be quality inspection report, environmental inspection report and other requirements, transmission data must be guaranteed, need to pass acceptance test.The dosage is relatively large.

Network cables are classified by material.

1, 4 cord iron 4 cord aluminum network cable(CCS Cable): poor transmission quality, it is easy to appear attenuation.The 100-meter resistance is about 50 ω, and the maximum transmission is about 60 meters.Identification method: use a magnet to attract the network cable, if it is sucked, on behalf of iron.

2, Copper clad copper wire(CCC Cable): also known as the bronze wire, the conductor of the bronze wire belongs to the copper of recycle.100 meters resistance is about 40 ω, about 80 meters can be transmitted, strong oxidation resistance, long service life.Identification method: because the surface is plated with a layer of oxygen free copper, the surface can not see what is different, but with fire, the oxygen free copper layer on the surface of the whole copper will soon melt away.

3,Copper coated aluminum network cable(CCA Cable): the material of copper coated cable is coated with a layer of oxygen-free copper on the surface of aluminum or aluminum/steel alloy core.The resistance of 100 meters is about 28 ω, which is cheap and good to sell. It can transmit about 100 meters, and has poor oxygen resistance and short service life.That is, the tensile strength is low.Identification method: with fire, if the core of the network cable quickly soften (this identification method is very practical), it proves that the copper core of the network cable contains aluminum.

4, high conductivity aluminum network cable: a kind of high performance copper, aluminum and silver alloy network cable.Small resistance, long transmission, resistance of 100 meters is about 20 ω, can be transmitted 120 meters, but poor resistance to oxygen, life is not long.This kind of network cable is subdivided into three kinds: copper coated aluminum (aluminum in the middle, the surface is a thin oxygen-free copper layer), high conductivity aluminum network cable (aluminum surface copper plating), copper coated silver (aluminum, full copper plating layer).Identifying method: Also use fire

5, copper coated silver wire: the main material is imported aluminum, interior and exterior leather are made of new materials.Resistance of 100 meters is about 15 ω, can transmit 150-180 meters, but poor resistance to oxygen, life is not long.Because copper coated silver can be transmitted far, we can generally use it in ADSL, computer room, supermarket and warehouse. There is no problem in general network transmission.Identification method: copper coated silver wire which also has a small amount of aluminum components, and aluminum is easy to be oxidized.It will probably be oxidized after four or five years of use.

6, oxygen free copper network cable(Pure Copper Cable): both inside and outside are new material, shiny is new material, can pull fine is new material.Kelan network cables are wang Yang copper core.Anaerobic copper cable 100 meters resistance is about 10 ω, about 120-150 meters can be transmitted, signal transmission distance is far, packet loss rate is low, so in the network engineering, network HD monitoring engineering and home decoration go dark line are recommended to use anaerobic copper, network stability is guaranteed, oxidation resistance is strong, long life.Identification method: in the process of burning, only the surface oxidation, wipe with paper, or restore yellow.It is important to choose the oxygen free copper cable: the resistance of the oxygen free copper cable is the least, and oxidation resistance.
