1.Standards
(1)ASTM B416 Standard Specification for Hard-Drawn Aluminum-Clad Steel Wire 
(2)IEC61232 Aluminium-clad steel wires for electrical purposes
(3)AS 1222.2 Part 2: Aluminium Clad (SC/AC)

2.Construction
Aluminum clad steel wire is a piece of round wire made of a round steel core clad with a uniform and continuous aluminum layer. By structure ratio of steel and aluminum, aluminum clad steel wire has different grades, LB14, LB20, LB23, LB27, LB30, LB35 and LB40, with corresponding electric conductivities of 14%, 20.3%, 23%, 27%, 30%, 35% and 40% IACS (IACS stands for International Annealed Copper Standard). Featured by high strength, corrosion resistance and high conductivity, etc.

3.Applications
Aluminum clad steel wire is widely used in coastal areas, volcano areas, salt atmosphere areas and overhead power line used in areas seriously polluted by industrial materials containing SO2, NO and CO2, etc. It's the optimum material for transmission conductor with kilometric span and carrier cable for electrified railways.

4.Features
ACS conductors are similar to conventional ACSR with some very important additional advantages. ACS can operate continuously at high temperatures up to 250C without damage, allowing for a significant increase in conductor current-carrying capacity. ACSS sags less under emergency electrical loadings than ACSR, it is self-damping, and its final sags are not affected by long-term creep of the aluminum.
(1)improved conductivity
(2)better self-damping property
(3)very low sag at high temperature
(4)high current carrying capacity
(5)excellent immunity to vibration fatigue
(6)long term creep of aluminum does not affect final sag
