The electricity industry has been evolving since its inception, including the case of cables. Aerial self-supporting cable has been able to replace the old cables by using technology and solving problems.. Aerial self-supporting cables have received a great deal of attention to reduce the risks to humans and animals. Then first to the definition of aerial cable and then Self-retaining cables (by air) we will pay.
Aerial cable
Overhead cables are cables used in masts and beams of transmission lines and above ground level.. This type of cable uses air as insulation and for this reason, it is less expensive and more common than other cables..
The alloy used in overhead cables is mainly made of aluminum. In some medium and low voltage transmission lines, as well as the connection to the consumer, copper cables are used..
What is an airtight cable?
Aerial self-supporting cables are actually a combination of aerial cables and self-supporting cables. Self-supporting cables in the category of aluminum cables are the best alternative to cables in low voltage power grids..
In self-supporting cables, in fact, six phase conductors, which are made of hard aluminum, are tightly twisted together, which is a feature in accordance with international standards..
benefits Use of aerial self-supporting cable
In the electricity industry, due to the high sensitivity of the work, a product will be successful when it can completely cover the defects of the previous product and provide extraordinary facilities to consumers and employees.. Here are some of the benefits of this type of self-supporting cable:
- Reduce costs in the wooded area
- Significantly reduce the risk of fire in forest areas and prevent animal death
- Ability to install a new line next to the old line and even on a power pole
- Increased freedom of action due to the reduction of the airspace cable distance
- Overhead cables are very inexpensive to maintain compared to other cables.
- High impact resistance of cables
- Reduce unauthorized use of electricity
- Enhance the beauty of the city: In fact, self-supporting cables can be routed through walls or hidden ducts.
- Increase the safety of employees and the general public
- Due to the lightness of the cables, the installation operation is done quickly.
- Can be used in tight spaces
- Can be installed on short bases due to the insulation of conductors
- Resistant to additional voltages caused by lightning
Such advantages in overhead self-supporting cables have led to the necessary measures to collect old cables and use self-supporting cables in most cities..
