What are The Advantages and Functions of Overhead Cables?
Overhead cable is often in sight, and if you are on a highway you will no doubt have seen it. It is a cable line that is erected on top of a tower or other method. This type of cable line is usually found in big cities, as the majority of the countryside does not take into account certain standards. So what exactly is called overhead cable? Overhead cable is composed of two or two groups of transmission lines together, and transmission lines are alias overhead lines, then you should now understand what is called overhead cable!
The Role Of Overhead Cables
The overhead cable transmits everyone's electricity to each territory and then is sent to each subsequent residential community, into household electricity, so the overhead cable for everyone is very important.
The Advantages Of Overhead Cables
1. High credibility of the power supply system, the choice of overhead cable can significantly reduce a variety of short-circuit fault common failures (especially the common short-circuit fault common failures of bare transmission lines in the airframe), compared with bare transmission lines in the airframe, the equipment failure rate is 4-6 times lower.
2. Good safety factor of the power supply system, is the choice of overhead cable so that personal safety and electrocution accident safety accidents significantly reduced. When the overhead cable in connection with the power supply, when the body or other small animals accidentally touches the surface of the cable line insulation layer if the cable line is not penetrated. It is not easy to cause adverse effects on both people and animals.
3. Convenient to build and overhaul, the overhead cable can be built on all types of towers, but also along the wall, in special cases can also be shuttled in the woods, immediately fixed immovably in the main pole with gold fittings.
4. Reasonable and effective, although the choice of overhead cable than the choice of bare transmission lines in the airframe should be more expensive, but cheaper than the general underground installation of cable lines. Therefore, its comprehensive engineering cost is lower, has more economic development, and is more effective.
ABC cable can include one or two additional conductors for public lighting and control pair.
Aerial bundled cable is widely used for temporary distribution of street lighting and secondary pole service cables.
The aerial bundled cables (ABC) for overhead distribution systems has been a good solution.
Types of Overhead Cable—Aerial Bundled Cable
Aerial cables are widely used in power transmission at home and abroad.
AAC, AAAC, and ACSR form part of the family of overhead conductors, transmission conductors, and power distribution conductors.
The conductors are manufactured with ridges for phase identification.
