Types of Transmission Line Conductor | Types of Transmission Line Wire
1) Solid Conductor
aluminum-solid-conductor-in-transmission-line
It is used in the bus of electrical substation but it is used in short distance bus.
2) Hollow Conductor
It is also used in electrical substation bus and it is also used in short distance bus.

Their length cannot be kept longer. Because if they are made longer then it will be very difficult to take them to the substation. Because these wires are difficult to bend easily.
3) Stranded Conductor
Aluminum Stranded Conductor in transmission lines
It is made of thin wire, due to which they can be bent easily and they can be transmitted quite easily from one place to another by wrapping it in a roll.
4) AAC - All Aluminum Conductor Transmission line
All the conductors in this are made of aluminum. That's why AAC wire does not get rusted. Because they do not rust easily, they are used more near water areas.
5) AAAC - All Aluminum Alloy Conductors in transmission line
Even in AAAC wire, all the wires are made of aluminum, but due to aluminum being very flexible, some other metal is mixed in it. Due to which their strength is increased.
They are used in railway crossings and hilly areas.
6) ACSR - Aluminum Conductor Steel Reinforced in transmission line
It is the most commonly used conductor. The wire between it is of Galvanized Steel. Due to which the strength of the ACSR conductor increases significantly.
Due to the use of steel in this conductor, it does not expand much when heated. For this reason, wherever we use the ACSR conductor, we can keep the gap between two electric poles more.
ACSR conductors are used on both high voltage lines and flame voltage lines.
7) ACAR (Aluminium Conductor Alloy Reinforced)
ACAR offers a middle ground between AAC and ACSR, combining elements of both conductor types.
8) AACSR (Aluminium Alloy Conductor Steel Reinforced)
AACSR excels in its high strength-to-weight ratio, making it ideal for applications where conductivity is less critical, such as earth wire applications.
Carbon Fiber Composite Conductors (CFCC)
Type Of ACSR Transmission Line Conductor
1) Dog – The conductor used from 33KV to 66KV is called a dog conductor. Its current carrying capacity is up to 300 amps. It consists of 6 strands of aluminum, and 7 strands of steel.
2) Panther – It is used from 66KV voltage to 132KV voltage. In this, current can be given up to 480 amperes. It consists of 30 strands of aluminum, and 7 strands of steel.
3) Zebra – Zebra conductor is used for 220kV voltage. In this, current can be given up to 735 amperes. Zebra conductor has 54 strands of aluminum and 7 strands of steel.
4) Moose – This conductor is used on 220 kilovolts or 440-kilovolt voltage lines, which can easily withstand current up to 800 amperes.
