1: Introduction
String cup, sound vibrations are traveling from the speaking end to the receiving end of the cup was the era that led to the invention of overhead cables, replacing the string with wires and poles replacing the cups.
The invention of overhead cables or suspended cables is with the pure intention to ease and facilitate the users. Such cables came into existence to transmit energy from one point to another.
2: What cables include overhead cables?
Following are the types of energy used to transmit;
- Electrical or power cables
- Telephone cables
- or tv cables
3: What are the advantages of overhead cables?
- Easy to install with no intensive or complicated labor training. Its installation cost is much cheaper than others.
- These cables do not produce a spark, which makes it capable of being installed adjacent to or near to trees.
- If a problem occurs, its maintenance is easily managed, making these cables the topmost priority in the market today.
- Our cables’ property of spark control makes it eco-friendly since it prevents the trees from being unnecessarily trimmed.
- During installation, it does not disturb the society, or the existing place as compared to underground wiring might do.
4: Are there any disadvantages associated?
Overhead cables are meant to be weather resistant; sun, rain, wind, etc. if not, it may lead to deterioration. Our cables are insulated with the best shield, helping its performance to increase and not decrease.
The number of poles has to increase with the increase in the weight of the cable, gravitational pull.
If installed haphazardly, it will lower the beauty of the area. Make sure to properly align, plan, and mark the areas to be installed.
5: What is overhead cable- Power line?
The power cables’ primary purpose is the distribution of electrical energy. Places that were left dark are now lit with brightness thanks to overhead cables.
These are inexpensive, convenient, and efficient solutions for transmitting electrical energy in abundance.
These power cables consist of conductors made from aluminum or wires made from copper are used when medium and low voltages are generated for transmission.
Selection of overhead power cable is made in three categories, ranging in voltages;
| Low voltage |
< 1000 volts |
Used in residential, commercial or for the purpose of utilities |
| Medium Voltage |
In between 1000 Volts – 69000 Volts |
Used in urban and rural areas |
| High Voltage |
100000 Volts or between 115000 and 138000 Volts |
Used to transmit electric power to many consumers |
| Extra high |
345000 volts to 800000 volts |
Used to cover long distances |
| Ultra-high |
>800000 volts |
Super fast and super powerful, 5x more power is transmitted in over a 6x more distance |
6: What is the Classification by length?
The length of an overhead cable plays a vital role in selecting a suitable type of cable. Generally, our cables are classified into three measures, which are as follows.
Short: These cables have a range of less than 60 Km.
Medium: These cables have a range of less than 250 Km but more than 80 Km.
Long: the cables having a length of more than 250 Km are specified in this category.
7: What are the Specifications?
IEC 61089: This is the standard provided for round wire over a concrete layer.
EN 50183: For wires having a material of aluminum, magnesium, silicon as alloys
BS 183: The list of specifications for wire, when made of galvanized steel, mostly used as earthing wire
BS: These are the specifications provided for when the copper wire is in use as a material for overhead cables.
Conductors
Copper, a material, has traditional values for ages. It is in use for overhead cables for a reasonable period.
It has the properties of strength, durability, flexibility, tensile strength, and high resistance to corrosion. But it has only one down factor and that is its cost.
Due to cost-effectiveness, copper is now in need of a substitute, here aluminum comes in handy.
Aluminum has all the essential properties, which makes it a compatible choice for replacement.
Aluminum in its properties makes up half the weight of copper, making it a low-cost choice, a feasible and economical choice.
Aluminum, when reinforced or mixed with alloys gives it double the strength making it the best economical, feasible choice
8: What are the Types of conductors?
There are three types of conductors available; AAC, ACSR, and AAAC.
- AAC– All Aluminum Conductor have no alloys mixed in it, purely aluminum properties, makes it a suitable choice for distribution of electric power at a local level.
It is used over wooden poles, transmission towers.
Its usage can vary to the transmission of extra high voltage for the distribution of power.
AAC (all aluminum conductor) is the most economical bare overhead conductor due to its lighter weight. It offers easier handing during installation and the use of simpler fittings. The wire is corrosion resistant due to its homogeneous construction.
The aluminum wires are twisted in a helix which each layer has more than the latter.

- ACSR– Aluminum Conductor Steel Reinforced has a mechanical strength more than All Aluminum Conductor.
The combination of aluminum’s high conductivity rate with the strength of the steel makes it an economical choice
It creates aesthetically pleasing wires with lesser sags and higher resistance due to the reinforced layer.
ACSR is used in all kinds of transmission towers variating in spans. These can transmit extra-high-voltage.
It consists of steel as its central core with aluminum alloy strands surrounding it helically. To prevent it from corrosion, it has a protective layer of zinc.
But when it comes to selecting AAAC and ACSR, AAAC is much preferred since no reinforced steel is involved.
But for clients who prefer reinforcement, our company provides the best of it with no errors or complaints.

Chapter 10: What is the communication cable?
Communication cable is also known as Power Line Communication (PLC).
PLC is solely meant to fulfill the purpose of communication. Instead of hearing one another voice, you can transfer data, any data, with the blink of an eye.
Nowadays, instead of having a separate cable, communication cable is infused with the power cable, aiming two shots from one arrow, both efficient and convenient.
Chapter 11: What are the properties of an overhead cable?
Overhead cables, however, ease may it can be hazardous to health or human life.
If not placed correctly in height, its magnetic flux may pull you away towards itself from the ground, proper considerations and calculations must be given a priority.
The properties of overhead cables are as follows;
It should have high tensile strength.
It should be resistant to corrosion and adverse effects of nature, wind storm, hail, sand storm, rain.
It should be adequately insulated for no loss of power; input should more or less be equal to output.
It should have high flexibility.
