What Should You Know About ACSR Conductors?
Posted by Dhruv Sharma on January 5th, 2022
A stranded conductor with hard drawn 1350-H19 aluminium wire on a galvanized steel wire is known as Aluminium Conductor Steel Reinforced (ACSR). For corrosion resistance, steel core wire is galvanized. Grease adds to the rusting. The proportion of steel and aluminium in ACSR conductors is determined by the application\'s mechanical strength and current carrying capacity. ACSR conductors are cost-effective and have a strong strength-to-weight ratio. ACSR moose conductor combines aluminium\'s low weight and superior conductivity with steel\'s high tensile strength. ACSR allows overhead conductors to have greater tensions, less sag and longer span lengths.
Palriwal Industries Pvt Ltd manufactures ACSR conductors that fulfil all national and international standards.
Aluminium Conductor Steel Reinforced (ACSR) is the full form of ACSR conductor. As the name implies, the conductor is made up of both aluminium and steel. The inexpensive cost and nearly identical resistivity of aluminium to copper is why aluminium is chosen as a conductor here. This conductor is made of steel to increase its strength, which is important because ACSR conductors are used in power transmission lines.
What Are the Types of ACSR Conductors?
Weasel Conductor
Seven strands make up the weasel conductor. Six of the strands are aluminium, while one is steel. A weasel conductor has a diameter of 2.59 mm for each strand. The conductor has a 7.77 mm overall diameter and a 30 mm area. The Weasel conductor\'s current carrying capacity is 144A, and its breaking load is 11.12 kN.
Rabbit Conductor
The ACSR rabbit conductor is made up of seven strands. Six of the seven strands are made of aluminium, while one is made of steel. Each strand in a Rabbit conductor is 3.35 mm in diameter. The conductor\'s total diameter is 10.05 mm, and its area is 50 mm. Weasel conductor has a breaking load of 18.25 kN and a current-carrying capability of 152A. The diameter of the strands differs between rabbit and weasel conductors, which affects all the conductor\'s qualities.
In 11KV lines, a Rabbit conductor is utilized. As a result, it\'s utilized to send power from the Power Substation to the Distribution Transformer.
Dog Conductor
There are 13 strands in the dog conductor. Six of the 13 strands are made of aluminium, while the other seven are made of steel. Aluminium strands have a diameter of 4.72 mm, whereas steel strands have a diameter of 1.57 mm. The conductor\'s total diameter is 14.15 mm, and its area is 100 mm. The dog conductor\'s breaking load is 32.41 kN, and its current carrying capacity is 239A.
Panther Conductor
A total of 37 strands makes up the panther conductor. Thirty of the 37 strands are aluminium, while the remaining seven are steel. Each strand is 3.0 mm in diameter. The conductor has a 21.0 mm overall diameter. The dog conductor\'s current carrying capacity is 395A, and its breaking load is 89.67 kN.
In 33KV lines, a Panther conductor is also utilized. It is used to transport electricity from a power generation plant to a power substation, and it is more efficient than a dog conductor.
