Introduction to the Characteristics of Overhead Cables

First understand what an overhead cable is. As the name suggests, overhead cables are cables erected in the air. Any tower can be erected with overhead cables. In special situations, you can even erect overhead cables on trees. Its land occupation rate is low. Its cost is also relatively cheap. This is a cable suitable for transporting current over long distances. It is usually used in remote areas and areas with low population density.

Characteristics of Overhead Cables

1 The transmission is more stable and reliable when running power supply

The failure rate of overhead cables is much lower than that of overhead bare conductors

2It is safer to run when power is supplied

Overhead cables have more insulating sheaths than overhead bare wires. During operation and use, the overhead cable greatly reduces the possibility of personal injury or death due to electric shock. As long as the cable is not damaged, people or animals will not be hurt even if they accidentally touch the insulating surface of the cable.

3 Easy to install and easy to maintain

Overhead cables can also be erected without towers. This greatly reduces the construction cost, and at the same time increases the ease of erection of the overhead cable, and the construction is very convenient. Overhead cables do not require special maintenance in terms of maintenance, which also reduces the maintenance cost of cable lines.

4High performance-price ratio

Although the price of ZMS overhead cables is higher than that of overhead bare wires. However, combined with its service life and the reduction in construction and maintenance costs, the cost performance of overhead cables is higher than that of overhead bare wires.
