ACSR conductor (All Aluminum Steel Reinforced conductor)

ACSR conductor consists of a solid or stranded steel core surrounded by strands of aluminium (E.C. GRADE). ACSR Conductor may be manufactured forhaving a wide range of tensile strength as per requirement. The principal advantage of these conductors are high tensile strength and light weight with longer spans as well as with lesser supports. Due to the greater diameter of ACSR Conductor a much higher corona limit can be obtained causing big advantages on high as well as extra high voltage overhead lines.

ACSR conductor:
Aluminum 1350 wires and the steel cores are concentrically stranded and wrapped helically around a central wire. The additional corrosion protection is available through the application of grease to the cores or infusion of the complete cable with grease.

Construction:

1. Aluminum 1350H19 wires, concentrically stranded about a steel core. Standard core wire for ACSR is class A galvanized.
2. Class A core stranding is also available in zinc-5% aluminum-mischmetal alloy coating.
3. For aluminum-clad (AW) ACSR, please refer to the ACSR/AW catalog sheet.
4. Additional corrosion protection is available through the application of grease to the core or infusion of the complete cable with grease.
5. ACSR conductor is also available in non-specular.

Application:
Used as bare overhead transmission conductor and as primary and secondary distribution conductor and messenger support. ACSR offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing ampacity.

1.Transmission and distribution of electric power had large span.
2.Transmission and distribution of electric power with high and very high voltage.
3.Electric power distribution from Power Station to sub cities.
