The difference between power cable and overhead cable

Time of Issue:

2021-03-10

　　1. Power cables occupies less land. Generally, they are buried in the soil or indoors, in trenches, tunnels, and the insulation distance between the lines is small. There is no need for poles and towers.

　　2. The power cable has high reliability. It is less affected by climatic conditions and the surrounding environment, with stable transmission performance and high reliability.

　　3. Power cables have more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature, superconducting power cables, etc.

　　4. The distributed capacitance of power cables is larger. The opposite is true for overhead cables.

　　5. The maintenance workload of power cables is less. The opposite is true for overhead cables.

　　6. The possibility of electric shock is small for power cables. The opposite is true for overhead cables.

　The production of wires and cables is completely different from the production methods of most electromechanical products. Electromechanical products usually adopt the assembly of other parts into parts, and the assembly of multiple parts into a single product, and the products are measured by the number of units or pieces. Wire and cable are based on length as the basic unit of measurement. All wires and cables start from the processing of conductors, and add insulation, shielding, cabling, and sheathing layer by layer to the periphery of the conductor to make wire and cable products. The more complex the product structure, the more layers of overlap. We will see various types of wires and cables in our daily lives. Today, let's talk about the process and characteristics of making wires and cables in detail...

What are the advantages of copper core cables compared to aluminum core cables?

With the improvement of people's living standards and the rapid advancement of science and technology, more and more copper core cables are replacing aluminum core cables on the market. Today, I will analyze the advantages of the comparison between the two. 1. Low resistivity: the resistivity of aluminum core cable is about 1.68 times higher than that of copper core cable...
