The Advantages and Functions of Overhead Cables

Overhead cables are often in sight, and if you are on a highway you will no doubt have seen them.

 It is a cable line that is erected on top of a tower or other method, and this type of cable line is usually found in large cities, as the majority of the countryside does not take into account certain standards.

 So what exactly is called a cable line? 

Overhead cable is composed of two or two groups of transmission lines together, and transmission lines are alias cable, so you should now understand what is called overhead cable!

The function of the overhead cable:

The overhead cable to transfer everyone's electricity to each region, and then sent to each subsequent residential area, turned into the household electricity, so the overhead cable is very important for everyone.

Advantages of overhead cable:

1, high reliability of the power supply system, the choice of overhead cable can significantly reduce a variety of short-circuit fault common faults (especially the common short-circuit fault common faults of bare transmission lines), and bare transmission lines compared to the airframe, the equipment failure rate is 4-6 times lower.

2, the power supply system safety factor is good, the choice of overhead cable so that personal safety electrocution accident safety accidents significantly reduced, when the overhead cable in connection with the power supply, when the body or other small animals accidentally touch the surface of the cable line insulation layer, if the cable line does not penetrate, it is not easy to cause adverse effects on people and animals.

3, easy to build and maintain, the overhead cable can be built on all types of towers, can also be built along the wall, special circumstances can also be shuttled in the woods, immediately fixed with gold fixtures immobile on the main pole.

4, reasonableness and effectiveness, although the choice of overhead cable than the choice of empty frame bare transmission line in the price should be more expensive, but cheaper than the general underground installation of the cable line. Therefore, its comprehensive engineering cost is obviously lower, more economic development, and more effective.
