The main application of ASCR wire and cable is in the overhead transmission lines. The specification and property of the aluminum made it suitable for utilization in this application.
acsr overhead line
Insulation should almost always be utilized as the first line of defense when protecting conductors against electric shock.
When this layer is drawn over the conductor, it becomes the wire, and when the shield and the armor are pulled over the wire, it forms a structure that is known as a cable because it is cohesive.
Antenna cables with XLPE sheaths can be found in a wide variety of applications and can be utilized for a variety of purposes.
Because of their qualities and characteristics, such as the ease with which they can be deployed and maintained, antenna cables are most commonly used for telephone lines and the transfer of electrical power. They are also widely employed in open space installations.
When shopping for cables with overhead lines, make sure to pay attention to the following points.
Conductors for antenna cables can be composed of copper or aluminum.
Aluminum conductors are also an option.
The voltage classes that can be supported by these cables range from 1 to 36 kV. Aluminum cables have replaced copper cables due to the high durability, high cost, and unavailability of copper cables.
Copper cables have excellent strength and conductivity and can be a viable choice for overhead lines. Aluminum cables have replaced copper cables.
Aluminum cables are distinguished by their amazing qualities, which can be attributed to the light weight of the cables as well as their excellent conductive surface.
Overhead wire made of shielded copper
Fixed copper aerial cables offer excellent resilience to the effects of a wide range of climatic conditions and are protected against the effects of moisture by hygroscopic tape.
Because of its high tensile strength and sturdy construction, this cable is regarded as being second only to high voltage cables in terms of quality.
Installation on beams, for use in telecommunication lines, and in mountainous regions are a few of the applications that can make use of this kind of cable
Cable in the air that can support itself
The self-supporting wire that runs overhead is not only simple to install but also provides a high level of safety.
The majority of these cables are only put in place temporarily, and once their purpose has been served, they are removed and replaced with authentic and permanent cables.
These cables have a very low weight and are capable of withstanding voltages of up to 36 kV.
air communication cable
These cables are extremely resistant to the effects of weather, rust, and sunlight on account of the sturdy casing that they have.

Different kinds of aluminum wires for the skies
Aluminum conductor of the AAC cable: Due to the cable's low strength, its use is restricted to the transmission and distribution of electrical power.
On the other hand, because of its high conductivity, it is typically reserved for low voltages and locations in which the electrodes are only a short distance apart from one another.
The conductor made of aluminum alloy AAAC: This cable offers both high resistance and a good amount of strength.
This product performs exceptionally well in coastal environments, which are prone to corrosion.
Buy a cable with an ACSR-type air conductor since it is the most common form of conductor used for power transmission.
This type of conductor is aluminum and it is reinforced with steel.
This aerial cable has a steel core and numerous layers of spiral aluminum wires.
Its resistance to corrosion is superior to that of galvanized or aluminized steel, and it has a good number of layers of spiral aluminum wires.
ACSR and AAAC cables are frequently utilized for high voltage and long distance poles due to their low weight and cost.
High-purity aluminum wire is wound around cores made of aluminum, magnesium, and silicon to create ACAR Aluminum Conductor, Reinforced Alloy, which has superior mechanical strength and electrical resistance.
The use of this product for distribution lines and overhead lines is by far the most typical use.
The benefits of investing in an overhead cable
A novel approach to the delivery of power is represented by antenna cables.
When compared to the conventional bare conductor power distribution system, this system has the advantages of having a low cost of installation, being easy to maintain, having a high operating efficiency, having a high safety and reliability rating, having a low power loss, having stable voltage regulation, and having high economic benefits.
The distribution system is perfect for use in rural areas, and in particular, for installations in locations with challenging topography, such as mountains, dense forests, coastal areas, etc.
It is possible to install these wires without having to fell any trees.
In addition, this cable is widely regarded as the superior option for the task of power distribution in highly populated urban regions.
Because of its insulating characteristics, it is a particularly practical material to employ in locations that are heavily built up and in spaces that are narrow between buildings.
These are also places where it is generally impossible to run bare wires.
In addition, the insulation on the cable protects the user from any potential electric shock.
When shopping for cables, one must keep in mind that doing so with overhead conductors might result in significant financial savings.
A further advantage of having the wires in plain view is that any problems may be located and fixed with minimal effort and speed.
Overhead cables that are dependable and secure
Aerial cables are extremely dependable and built with appropriate insulation that allows them to survive extremes of temperature as well as direct sunlight.
Insulation lessens the likelihood of short circuits and protects against overvoltage and the destruction of transformers caused by lightning strikes.

Installing it also requires very little in the way of additional hardware and accessories.
For electricity distribution systems with an overhead voltage of 15 kV or 25 kV, overhead lines are the optimum alternative for distribution firms since they can be simply run on poles in locations with limited space.
The many positive aspects of aluminum cable
- Aluminum is offered at a price that is more reasonable than copper.
- When compared to other conductors, aluminum is relatively lightweight (given its bulk).
- Simple assembly required
- Lightweight and convenient to carry
- reusable
4 drawbacks associated with the use of aluminum cables
- However, as a downside of aluminum cable, we shall address its relative weakness in comparison to other cables of a similar type:
- Dependence on temperature in terms of dimensions brought forth by a high coefficient of thermal expansion (large longitudinal change in temperature change)
- Due to the high reactivity of metals, it is possible for them to react with air, which results in the formation of a metal oxide layer, which in turn increases resistance.
- Due to its high resistance, aluminum cables need to have a wider diameter than copper cables in order to meet industry standards.
This product will be highly beneficial exactly as the copper model if the issues that have been pointed up above can be resolved.
Obviously, these issues can be resolved by implementing the following reforms:
In order to prevent issues that are brought on by shifts in temperature, cables are typically installed in areas where there is no risk of them becoming too short, and they are not typically utilized for the wiring of the inside of structures.
If you are concerned about the reaction of aluminum with air, you should know that in order to prevent this reaction and fire due to electrical resistance, special insulators are used in the cable cover to minimize the conductors' contact with air.
If you are concerned about the reaction of aluminum with air, you should know that this reaction can be prevented by using special insulators. outdoor.
People also worry about the high resistance of aluminum cables, which can lead to an increase in the temperature of the wires and even a fire; however, there is a workaround for this issue.
Aluminum cables can be insulated to reduce this risk.
In the event that proper tables are utilized in the cable selection process, such as copper-aluminum cable diameter conversion tables, issues of this nature do not emerge.
It is important to keep in mind that the diameter of the aluminum cable in this scenario needs to be greater than that of the copper wire.
