Types of Conductors use for Transmission Line

In this article, you are going to find more about which types of conductors used for the electrical power transmission line.

In overhead power transmission lines suspended by towers and in this type of situation the bare conductor on the transmission line is generally made out by using Aluminium materials. There are various types of conductors which are used transmission line. The most common conductors which use transmission line are Aluminum Alloy Conductors.

When we consider the types of conductors, the following are best conductors use for power transmission lines.

 

• All Aluminum Conductor (AAC)
• All Aluminum Alloy Conductor (AAAC)
• Aluminum Conductor Steel Reinforced (ACSR)
• Aluminum Conductor Aluminum-Alloy Reinforced(ACAR)
• Bundle Conductors

You can find more about these conductors in here.

There are various types of sub conductors which use for Aluminum Alloy Conductors are AAAC-HS, AACSR, ABB and ACAR.

These types of conductors are use for a transmission line for all over the world over four decades.

Normally high voltage transmission line varying from 66kV To 400kV voltage levels.

AAC and ACSR are the most common type of conductors which use in the transmission line.

 ACAR ( Aluminium Conductor Alloy Reinforced)

Aluminium Alloy conductor got great mechanical strength and overall electrical conductivity of the ACSR (Aluminium Conductor Alloy Reinforced) conductivity is between 56% to 60%.

AACSR (Aluminum Alloy Conductor Steel Reinforced)

Aluminum Alloy Conductor Steel Reinforced (AACSR) conductor consist of the high mechanical strength high tensile galvanized steel core covered with Aluminum alloy wires. This type of conductors can use for any rough mechanical circumstances.

ACSR (Aluminium Conductor Steel Reinforced) Conductors

Aluminum Conductor Steel Reinforced (ACSR) Conductors consist of more than seven Aluminum and steel conductors. Center of the conductors comprised galvanized steel and outer layers of the galvanized steel comprise Aluminum conductors. These types of conductors are much use for long spans of transmission lines because these lines got high tensile strength.

AAAC-HS and AAAC_HS type Conductors

The conductor of AAAC-HS consist the heat treatable Aluminium Alloy wire.elongation for this wire is more than 4% and conducting of AAAC-HS wire is normally higher than 52.5%. AA 6201 wire is the most commonly used wire in AAAC-HS type Transmission line conductor. AAAC- HC is also much Like AAAC-HS conductors and UTS of this conductor is varying between 20-26 kg/mm2 and elongation is vary between 2% to 4% .unlike AAAC-HS, AAAC- HC  conductivity is little bit higher which is 56% to 59%.

Bundle Conductors

Bundle conductors are widely used for the transmission line and have its own advantages and disadvantages. Bundle conductor is a conductor which consist of several conductor cables which connected. Bundle conductors also will help to increase the current carried in the transmission line. The main disadvantage of the Transmission line is its having high wind load compared to other conductors.

Conclusion:

Hope that you have got know more information about types of conductors used for transmission lines. Also get know such conductors like AAC, AAAC, ACSR, ACAR, and bundled conductors.
