What type of conductor is ACSR?
Aluminium conductor steel
Aluminium conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines. The outer strands are high-purity aluminium, chosen for its good conductivity, low weight, low cost, resistance to corrosion and decent mechanical stress resistance.
What is the meaning of ACSR wire?
Aluminum Conductor Steel Reinforced
ACSR – Aluminum Conductor Steel Reinforced is used as bare overhead transmission cable and as primary and secondary distribution cable. ACSR offers optimal strength for line design. Variable steel core stranding for desired strength to be achieved without sacrificing ampacity.
Where ACSR conductors are used?
The ACSR is filled with steel on the inside. So the ACSR conductor is used in the overhead transmission line, in earthing wire, and in long-distance and river crossing works. It can be made with different tensile strengths. Due to the high diameter, a very high brightness range can be achieved.
What is the difference between AAC and ACSR conductor?
ACSR (aluminum conductor steel-reinforced) has a long service record because of its economy, dependability, and strength to weight ratio. AAC (all aluminum conductor) is the most economical bare overhead conductor due to its lighter weight.
What is the advantages of ACSR conductor?
ACSR conductors combine the light weight and good conductivity of aluminium with the high tensile strength and ruggedness of steel. In line design, this can provide higher tensions, less sag, and longer span lengths than obtainable with most other types of overhead conductors.
Why ACSR is better than AAC conductor?
ACSR has lower strength to weight ratio ranging between 88.4:9.4; hence requires lesser spans than AAAC. Lower cost of ACSR is offset due to higher cost of towers etc. Suffers no reduction in strength on temperature rise upto 90 C since it is specially heat treated at 160 C temps.
Which is better ACSR or AAAC?
AAAC are used as a bare conductor cable on aerial circuits that require a larger mechanical resistance than the AAC and a better corrosion resistance than the ACSR. The sag characteristics and the strength-to-weight ratio of the AAAC conductor cable is better than both AAC and ACSR.
