Aluminum Conductor Steel Reinforced (ACSR)

Product Description

Applications(ACSR)
ACSR are available in a range of steel contents ranging from 6% to 40% for additional strength. The higher strength ACSR conductors are commonly used for river crossings, overhead earth wires, and installations involving extra-long spans. The ACSR conductor can, against any given resistance, be manufactured to different tensile strengths, so a high tensile strength combined with its lightweight properties means it can cover longer distances with fewer supports. Due to the greater diameter of the ACSR conductor, a much higher corona limit can be obtained which is advantageous on high and extra high voltage overhead lines.

Advantages:
1.  Simple structure, convenient erection and maintenance
2. Low cost, large transmission capacity
3.Good electrical conductivity and enough mechanical strength, high tensile strength.

Structrue: concentric-lay- stranded
ACSR is concentrically stranded conductor with one or more layers of hard drawn  aluminium wire on galvanized steel wire core. The core can be single wire or stranded depending on the size. Steel core wire is available in Class A , B or Class C galvanization for corrosion protection. Additional corrosion protection is available through the application of grease to the core or infusion of the completed conductor with grease.
