AACSR Conductor Overhead Bare Conductor Transmission Line

AACSR Conductor – The full name: Aluminum Alloy Conductor, Steel Reinforced. These homogeneous conductors in aluminium alloy show many advantages i.e lightness, high breaking load allowing long spans, simplificity of the accessories and lastly easy recycling. These conductors are suitable for the long spans network. Used as bare overhead transmission cable and as primary and secondary distribution cable. AACSR offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing Ampacity.

Construction

AACSR is a concentrically stranded conductor composed of one or more layers of 6201 -T81 aluminum alloy wire stranded with a high-strength coated steel core. The core may be single wire or stranded depending on the size.

The proportions of aluminum alloy and steel can be varied to obtain the relation between current carrying capacity and mechanical strength best suited to each application.

Core wire for AACSR is available with Class A, B or C-galvanized; "aluminized" (AZ): or aluminum clad (AW).

Additional corrosion protection is available through the application of grease to the core or infusion of the complete cable with grease.
