What is Overhead Cable？

Many people are confused by the fact that overhead cables are different from ordinary power cables.

Definition of Overhead Cable

Overhead cable (full name overhead insulated cable) is an overhead conductor with an insulation layer and a protective jacket. It is a special kind of cable, the production process of which is similar to that of cross-linked cable, and it is a new way of transmission between overhead conductors and underground cables.

Overhead cable is a cable construction method in which the cable hangs from a pole at a certain height above the ground. Overhead cables are usually single-core.

Compared to underground cables, overhead cables are more susceptible to outside influences, less safe, and less aesthetically pleasing. However, it is easy to erect and has low construction costs, so it is still widely used in places where laying underground cables is difficult.

In the city's old power grid transformation mostly use Overhead cable. Shanghai was the first to use overhead lines from 1 to 10 kV for 100 km. Subsequently, Guangzhou, Beijing, Shenyang, Wuhan, and Dalian used overhead cables in their major cities and tourist attractions.

ZMS Cable, established in 1990, is a global supplier of high-quality cables and cable accessories with a wide range of medium, high and low voltage cables. Depending on the application of the power line, there are overhead cables, rubber cables, welding cables, cross-linked polyethylene cables, PVC cables, bare cables (AAAC, AAC, ACSR, BCC), etc.

Advantages of Overhead Cables

1. High reliability of power supply, good safety.

2. Easy to erect and maintain.

3. Reasonable economy.

Power cables are cables with high-quality insulation material outside the conductor and various protective layers. The function of power cables is the same as the overhead cables, both transmitting and distributing high-capacity electrical energy through the power system.

The Difference between Overhead Cable and Power Cable

1. Power cables can lay in a variety of environments, safe and concealed, not subject to the interference of external climate change.

2. Less maintenance, durable.

3. Power cable structure is more complex, manufacturing processes.

4. Product prices are dozens of times higher than overhead wires. 

5. Power cables focus on the use of power distribution, power consumption side.

Overhead cables focus on the transmission, transformation, distribution part of the generation of power. Because of the cost of power cables and the complexity of the structure, the construction of power projects often uses an overhead power line.
