ACSR conductor IEC61089 A1/S1A 120/20mm2 (al26/2.38, st7/1.85)
Aluminum Conductor Steel Reinforced (ACSR) conductor are stranded conductors and the central strand is made up of steel and the outer strands are made up of aluminum. The aluminum strand serves the purpose of transmitting the voltage. That means the aluminum layer acts as a conductor.
APPLICATION
ACSR conductors are known to have more strength and conductivity and are are popular among different conductor configurations for transmission of voltage. ACSR conductors are used almost extensively in all countries to transmit huge amounts of voltage from one end to another. Due to their stranded nature, they are easy to transport, unlike in solid conductors that break during transportation and handling issues.
REFERENCE STANDARD
Basic design to BS 215-2 / BS EN 50182 / IEC 61089 / ASTM B 232/B 232M / DIN 48204 / JIS C 3110 standards.
