"Fenjiang" copper core cable has more advantages than aluminum core cable

"Fenjiang" cable, copper core raw materials are selected from Tianjin Dawu, Zhengwei Group, Jiangxi Copper (14.
77 +0.
07%, buy) and many other domestic non-ferrous metal complete industrial chain as the leading group companies to provide high-precision, high-purity, impurity-free high-quality raw materials
.
Therefore, the copper core cable of "Fenjiang" has more advantages than the aluminum core cable:

1.
Low resistivity: The resistivity of aluminum core cable is about 1.
68 times
higher than that of copper core cable.

2.
Good ductility: the elongation rate of copper alloy is 20~40%, the elongation rate of electrical copper is more than 30%, while the aluminum alloy is only 18%.

3.
High strength: the allowable stress at room temperature, copper is 7~28%
higher than aluminum.
Especially the stress at high temperatures, the difference between the two is even
greater.

4.
Fatigue resistance: aluminum is easy to break after repeated bending, but copper is not easy
.
In terms of elasticity indicators, copper is also about 1.
7~1.
8 times
higher than aluminum.

5.
Good stability and corrosion resistance: the copper core is oxidation and corrosion resistant, while the aluminum core is easily oxidized and corroded
.

6.
Large ampacity: Due to low resistivity, the copper core cable of the same section is about
30% higher than the allowable ampacity (maximum current that can be passed) of the aluminum core cable.

7.
Low voltage loss: Due to the low resistivity of the copper core cable, the same
current flows through the same section.
The voltage drop of the copper core cable is small
.
Therefore, the same transmission distance can ensure higher voltage quality; In other words, under the allowable voltage drop conditions, the copper core cable transmits electric energy to a long distance, that is, the power supply coverage area is large, which is conducive to network planning and reduces the number
of power supply points.

8.
Low heating temperature: Under the same current, the heat generation of the copper core cable of the same section is much smaller than that of the aluminum core cable, which makes the operation safer
.

9.
Low energy consumption: Due to the low resistivity of copper, the low power loss of copper cables compared to aluminum cables is obvious
.
This helps to improve the efficiency of power generation and protect the environment
.

10.
Anti-oxidation and corrosion resistance: The connector of the copper core cable has stable performance and will not cause accidents
due to oxidation.
The joint of the aluminum core cable is unstable, and accidents often occur due to oxidation that increases the contact resistance and
heats up.
Therefore, the accident rate is much
larger than that of copper-core cables.

11.
Convenient construction: (1) The copper core is flexible and the allowable bending radius is small, so it is convenient to bend and easy to penetrate the pipe; (2) The copper core is fatigue-resistant, and repeated bending is not easy to break, so the wiring is convenient; (3) The mechanical strength of the copper core is high, and it can withstand large mechanical tensile forces, which brings great convenience to the construction and laying, and also creates conditions
for mechanized construction.

Although aluminum core cables and cheap, the copper cables of "Fenjiang" have outstanding advantages
in cable power supply, especially in the field of underground cable power supply.
The underground use of "Fenjiang" copper core cable power supply has the characteristics of
low accident rate, corrosion resistance, high reliability, convenient construction and maintenance.
This is also the reason why copper cables are mainly used in the power supply of underground cables in China
