ACSR or ACSR cable or ACSR conductor used for Overhead electrical distribution and transmission lines for distributing power. 

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

Construction: 
Aluminum alloy 1350-H-19 wires, concentrically stranded about a steel core. Core wire for ACSR is available with class A, B, or C galvanizing; ""aluminized"" aluminum coated (AZ); Or aluminum-clad (AW). Additional corrosion protection is available through the application of grease to the corer or infusion of the complete cable with grease. 

Specifications: 
ACSR bare conductor meets or exceeds the following ASTM specifications: 
B-230 Aluminum Wire, 1350-H19 for Electrical Purposes 
B-231 Aluminum Conductors, Concentric-Lay-Stranded 
B-232 Aluminum Conductors, Concentric-Lay-Stranded, Coated Steel Reinforced (ACSR)

B-498 Zinc-Coated Steel Core Wire for Aluminum Conductors, Steel Reinforced (ACSR/AZ) 
B-500 Zinc Coated and Aluminum Coated Stranded Steel Core for Aluminum Conductors, Steel Reinforced (ACSR) 

 

 

 

 

 

 

 

ACAR conductor aluminum conductor alloy reinforced

Brief Description:

The use of ACAR is a very interesting option to some bare transmission and distribution lines. The wires of Aluminium Alloy 6201 reinforce mechanically the conductor as core having the same role of steel in ACSR, but with much higher ampacity. Its combination with Aluminium 1350 – H19 wires result in a good and interesting balance of mechanical strength and electrical performance.

 

Applications:

ACAR is used as bare cable for overhead transmission and distribution lines and also as bus-bar in substations where is highly suitable considering the mechanical and electrical characteristics. As comparison with ACSR of same weight, ACAR can offers higher ampacity and mechanical strength.

 

Features :

Aluminum Conductor Alloy Reinforced (ACAR)

cable is an excellent conductor choice where current

carrying capacity, higher strength and a lower conductor

weight are critical to the line design.

 

Construction:

Wires of Aluminium 1350-H19 is concentrically stranded on Aluminium Alloy 6201 core. The number of wires of each one depends on the cable design. In some cable constructions the wires of Aluminium Alloy 6201 can be distributed in layers throughout the Aluminium 1350-H19.

 

 

 

   Service Performance

(1).The permissible long-time operating temperature for aerial conductor is 70^oC.

(2).Under the circumstance that rare climate is occuring and ice coverage rate low in heavy ice area,the biggest stress of cable at the lowest point of the sag should not exceed 60% of the short-time destructive power.

(3).When connecting conductors,the conductor beside the connecting tube cant be prominent.Otherwise,the force on the operating conductors will be unbalanced.After connectors are install,the connecting tube should be painted by moisture-proof varnish in order to protect it from corrosion.

(4).Under installaion,the arc downing stress of all the conductors should be the same.With in the permissible distance of crossing buildings or dropping to the ground,the stress can be 10-15% higher than regular stress.

3.Product Performance

(1).The electrical performance of AAC and ACSR is indicated in DCΩ/km(20^oC).The resistivity of the hard aluminum wire for stranded wires is not greater than 28.264 nΩ. m of international standard value.

(2).The rated tensile strength of AAC is denoted with the result of total cross-section of all aluminum conductors multiplied by min.tensile of corresponding size specified in the standard for aluminum wire.
