Commonly used ACSR Conductors in India

by Helios A. Digital Media Marketing Executive

Aluminum Conductor Steel Reinforced (ACSR) is a type of high capacity ad high strength conductor. ACSR conductors are typically used in the overhead power line. High purity aluminum is used on the outer strands.

The reason why aluminum conductor is chosen because of its conductivity, low weight, as well as low cost. All the ACSR conductors used in the transmission and distribution line are given animal names and these are commonly used ACSR conductors.

Commonly, ACSR comprises of galvanized steel core of 1 wire or 7 wires or 19 wires and it is surrounded by concentric aluminum strands.

ACSR Weasel Conductor: Weasel conductor is usually used as a bare overhead transmission conductor. The material used in the conductor is aluminum and steel. It is commonly used for the primary and secondary distribution system and as a messenger conductor. Weasel conductor is used for voltage level up to 11 kV and its size has a nominal Al cross-sectional area of 30 sqmm.

ACSR Rabbit Conductor: ACSR Rabbit conductor has a nominal Al cross-sectional area of 50 sqmm. It is used for HT overhead applications. It has 6 aluminum strands of 3.35 mm diameter and 1 steel strand of 3.35 mm diameter. It has an inner core which is of stranded steel with a higher tensile strength than others. This increases the strength and supports the conductor’s weight. So it is possible for the conductor to resist wind, snow and other weather. Besides, the high strength can enable a longer span.

ACSR Dog Conductor: ACSR Dog conductor has a nominal aluminum cross-sectional area of 100 sqmm. It has high robustness and strength. Steel present in the inner core is higher in strength than aluminum, which allows for increased mechanical tension to be applied to the conductor. This type of conductor is suitable for extra-long spans and can resist any damage due to climatic changes.

ACSR Wolf Conductor: ACSR Wolf conductor has a nominal aluminum cross-sectional area of 150 sqmm. Wolf conductor has better connection and transmission properties when compared to ordinary Aluminum conductors. These conductors are used in High Tension overhead transmission of voltage up to 33 kV.

ACSR Panther Conductor: ACSR Panther conductor has a nominal aluminum cross-sectional area of 200 sqmm. The diameter of the aluminum wire is 30/3.00mm, and the stranding steel is 7/3.00mm. When compared with other type conductors, panther conductor has obvious advantages for its economical price, high tensions, and favorable weight. These conductors are used for transmission of voltage up to 33 kV.

ACSR Zebra Conductor: ACSR Zebra conductor has a nominal aluminum cross-sectional area of 420 sqmm. The zebra conductor has 54 aluminum strands and 7 steel strands of 3.18 diameters each. These conductors are used in High Tension overhead transmission for voltage range above 33 kV.
