2. ACSR (Aluminum conductor steel reinforced)
(1), Brief Description
ACSR conductor consists of a solid or stranded steel core surrounded by strands of aluminium (E. C. GRADE).
(2), Application
Widely used in power transmission lines with various voltage levels, because they have such good characteristics as simple structure, convenient installation and maintenance, low cost large transmission capacity. And they are also suitable for laying across rivers valleys and the places where special geographical features exist.

3. ACAR Conductor, Aluminum Conductor Aluminium Alloy Reinforced.
(ACAR) is an excellent conductor choice where current carrying capacity, higher strength and a lower conductor weight are critical to the line design.

4. AAAC, All Aluminum Alloy Conductor
(1). Standard: BS EN 50183, ASTM B399, DIN 48201
(2). Specification: AAAC are composed by bare concentric-lay-stranded aluminium alloy wires.
(3). Application: Used as bare overhead conductor for primary and secondary distribution. Designed utilizing a high-strength aluminum alloy to achieve a high strength-to-weight ratio; Affords better sag characteristics. Aluminum alloy gives AAAC higher resistance to corrosion than ACSR.

5. ACSS, ( Overhead Aluminium Conductor Steel Supported).
(1), Construction
A non-homogenous conductor, is a concentric-lay stranded conductor made from round aluminum 1350-O wires and round, coated steel core wire(s). Steel wires are coated with Class A coating of zinc – 5% aluminum mischmetal alloy. Other Classes of coatings are also available for additional protection from corrosion. Standard, High, Extra and Ultra High Strength steel are also available.
(2), Features
ACSS conductors are preferred over ACSR conductors for specific transmission line applications:
With zinc – 5% aluminum mischmetal alloy coating on steel wires, ACSS conductors can be operated up to 250 ° C.
ACSS conductors carry more current than ACSR conductors due to: Minimum average conductivity of 63% IACS for 1350-O aluminum wires vs. An average conductivity of 61.2% for 1350-H19 aluminum wires in ACSR.
ACSS conductors can be operated up to 250 ° C vs. The maximum operating temperature for an ACSR conductor does not exceed 100 ° C.
ACSS conductors are prone to resist the effects of aeolian vibration due to very little or no mechanical load on the annealed aluminum wires.
Long term creep is not a factor when designing with ACSS conductors.
